Control Network A control network is a Local Area Network (LAN) that connects controller devices such as autonomous controller FCNs/FCJs or PLCs, and VDS data servers. The reliability and real-time operation are required by this type of network that performs critical communications continuously over the network. Field Network A field network is a small and slow network connecting FCNs/FCJs and intelligent filed devices or remote I/O devices. Typical examples are FF-H1, PROFIBUS, DEVICENET and Ethernet. FCNs/FCJs support FF-H1 and Ethernet in R1.11 and later. Control System Information Network A control system information network is a LAN that connects VDS data servers, VDS HMI servers (commonly exist on the same PC with VDS data server) and HMI clients. On a small system, the level of control system information network can be submitted by connecting VDS HMI servers and HMI clients to control networks. Information Network (Intranet) An information network is a backbone of intra-company information system LAN. Wide Area Network (WAN, Internet) A WAN is a network that spans geographically dispersed area, such as public line or internet; a variety of network are available through public switched phone networks, leased lines, satellites, IP networks, etc. FCN-500, FCN-100 An FCN-500 and an FCN-100 are a controller of the module mount type that is connected to control networks, with highly reliable features, allowing to duplex the control network, CPU, power supply and internal bus for connecting I/O module. FCN-RTU An FCN-RTU (Low power Autonomous controller) is a compact controller assembled with a CPU module with built-in analog, digital I/O, communication ports, and a base module. Eight arbitrary I/O modules can be installed. FCJ An FCJ is an all-in-one type controller that is connected to control networks, and can be installed in devices at sites. It is possible to duplex control networks. FCJ cannot be enhanced with I/O modules since it has a built-in I/O interface. In addition, it cannot duplex the CPU, power supply and internal bus for connecting I/O module. Other functions are same with FCN. Field Devices (supporting field networks) These are intelligent field devices supporting field networks. These devices support FF- H1 and Ethernet. PLC Other suppliers' PLCs supporting Ethernet communication can be connected to control networks. VDS Data Server A VDS data server acquires control data from controllers on control networks, providing upper computer such as VDS HMI servers with abstracted data.

VDS HMI Server A PC equipped with Web-based HMI server functions. Normally, HMI servers and data servers run on the same PC. On some large scale systems, they can run on separate PCs. HMI (VDS Viewer) An HMI is a Web-based VDS HMI client device that provides operation and monitoring windows. A PC equipped with Java VM (Virtual Machine) is used. Configuration PC A configuration PC is a PC that creates and downloads control logics of FCN/FCN- RTU/FCJ or field devices, and configures devices. You use this PC with installing configuration tools, to connect to control networks when starting up the system. You can install configuration tools on a PC on which VDS runs, to reduce the number of PCs. The configurations other than the basic network settings (IP addresses) of FCN/FCN- RTU/FCJ can be made from remote PCs connected via routers.

1.2 Autonomous Controller FCN/ FCJ This chapter explains network interfaces of the autonomous controller FCN/FCJ.

FCN-500, FCN-100 and FCJ have two or four (FCN-500 with NFCP502 only) Ethernet network interfaces. If you do not duplex the control network, use only network interface1. Alternatively, they can be used as two or four separated networks. Each port is 10/100 Mbps and 1 Gbps (FCN-500 only), supporting full-duplex and auto negotiation functions. FCN-RTU has one Ethernet network interface. Except for the duplex function, the function of the FCN-RTU is the same as the FCN. Table Ethernet Interface CPU Model Network Interface Baud Rate NFCP501 2 ports 10/100 Mbps, 1Gbps NFCP502 4 ports NFCP100 2 ports NFCP050 1 port 10/100 Mbps NFJT100 2 ports

1.3 VDS This section explains the network interfaces of VDS.

The network interface cards used on a PC on which VDS is implemented, can be general-purpose ones supporting Fast Ethernet. STARDOM realizes duplexed control networks by software; therefore, it is not required that you use the same suppliers' network cards for both of them.

TIP Some suppliers' network adapters provide duplexed networks by themselves with two identical network adapters mounted. However, you cannot use the supplier-provided duplex function for STARDOM control network.

1.4 Network Devices Use hubs or routers to connect controllers and VDSs. Generally, there are two types of hubs: repeater hub and switching hub. Choose the optimum according to the feature of network, with consideration especially given to the performance and the wiring distance.

Important

Do not use 10 Mbps hubs or repeater hubs with the STARDOM system.

Hubs and Routers Repeater Hub The hub has the repeater function to connect two or more cables such as 10BASE-T, 100BASE-TX or 1000BASE-T. The repeater function is to relay transmission signals; it performs waveform shaping to the signal received from one segment, amplifying it to the given level to send to all other segments. This type of hub is used for connecting different media segments each other, lengthening the distance of the same segments or supporting the increase of the connecting nodes. Do not use repeater hubs with the STARDOM system, because trouble with performance may occur. Many repeater hubs do not support auto negotiation, and problems frequently occur when connecting to other devices. Switching Hub A switching hub has bridging features, enabling to store a received packet in the buffer, analyzing the destination address, and then forwarding it to the necessary port. Unlike repeater hubs, switching hubs do not relay frames to all segments, which enables to distribute loads of the network. In addition, some switching hubs have other varieties of features including the auto-negotiation, optical interface, 1 Gbps Ethernet interface, VALN, SNMP, STP, port mirroring, and Layer 3 switch. Router A router is a network device to transmit packets over networks based on the information of network layers. Routers have a function to route communication frames. Routers are used for connections between network domains or connections to WAN or other media. Recently, the routers with multi-functions such as security functions, firewall, and redundant network functions are generally used.

Main Functions of Network Devices This subsection explains the main functions and features of network devices for reference purposes to choose the optimum network device. Full-Duplex Full-duplex enables the transmission of data in two directions simultaneously (send and receive), avoiding the collision of the two. With Fast Ethernet, 200 Mbps bandwidth is enabled.

TI 34P02K25-01E Jun. 6, 2018-00

<1. Devices Overview> 13

Auto Negotiation The auto negotiation is a function to confirm the communication method to be employed between two ports connected to cables, through FLB Bursts signals. The selection between interfaces with different speeds (10 Mbps, 100 Mbps or 1 Gbps: FCN-500 only) or between different communication modes (half-duplex or full-duplex) is automatically performed. The communications between two devices should be one of the following combinations of communication speeds and communication modes. Table Combinations of Communication Speeds and Communication Modes 10M Half 10M Full 100M Half 100M Full 1G Full Auto 10M Half X - - - - X 10M Full - X - - - - 100M Half - - X - - X 100M Full - - - X - - 1G Half - - - - - X Auto X - X - - X

X: Possible -: Impossible

FCN/FCJ supports the auto negotiation features only. Therefore, specify auto negotiation (recommended) or 100 Mbps Half Duplex for a target connecting device of FCN/FCJ. Supporting 1 Gbps A switching hub with a port which supports data transfer rates of 1 gigabit per second. It is effective to use this hub for high-speed link between switches or between a switch and a server or to a backbone. 1000BASE-X, standardized in IEEE802.3z and 1000BASE-T, standardized in IEEE802.3ab are provided. For detailed specification, refer to the corresponding standards. VLAN VLAN is a function to divide a LAN logically within a switch. It imposes restrictions on the scope of forwarding broadcast packets, and divides logical groups, in which communications are established, enabling to construct a network so that each group may be connected to the separate switches. VLAN also realizes highly efficient network through the function to forward broadcast packets only within the same VLAN. SNMP SNTP is a switching hub with SNMP features to mange a network. SNMP is effective for monitoring networks or tracking down the source of failures remotely. Layer3 Switch Layer3 switch is a switching hub with routing functions implemented in the hardware. Faster routing operations and relatively reasonable prices than usual routers are attained in this switching hub.

Track Usage Record of Network Devices Track Usage Record of Hubs The following products were used for labo test of STARDOM. Table Track Usage Record of Hubs Manufacturers Product names/type names Remarks Cisco Catalyst2912/24 XL-EN Switching hub with management features Cisco Catalyst2950-24 Switching hub with management features 3Com SuperStack 3 Switch 3300SM 3C16985 Switching hub with management features Allied Telesis CentreCOM FS708XL Switching hub Allied Telesis CentreCOM FS708EXL Switching hub Allied Telesis CentreCOM FS808TPV1 Switching hub HP ProCurve Switch 2512/2524 Switching hub,0-55 °C

TIP • It takes several tens of seconds for switching hubs with management features to start a packet relay operation, because the initialization processing is generally carried out after they are turned on. Therefore, if an FCN with duplexed CPUs is connected to such a switching hub and if the FCN and the switching hub are turned on simultaneously, the APC (All Program Copy) processing may fail when the FCN is turned on. In this case, turn on the switching hub first. After the initialization processing of the switching hub is finished, turn on the FCN. • By default, the spanning tree protocol (a function to automatically set usual routes or routes when making detours in networks with multiple routes) is configured to Cisco’s switching hubs. In this case, hubs do not forward data to relevant ports for about 30 seconds after devices connected to the hubs were turned on. In order to avoid this problem, cancel the configuration for using the spanning tree protocol.

Cables Please avoid unplugging cables attached to a device by fixing it to a rack or other furniture, or taking other measures. Generally used LAN cables are listed as follows. UTP Cables A UTP cable is the most commonly used unshielded twisted pair cable. Use category 5 or higher UTP cables. There are 4-conductor cables and 8-conductor cables; the both type can be used. Make a choice between a cross cable and straight cable according to the intended purpose. Generally, a straight cable is used when the connection is made between a node and a hub; a cross cable is used when the connections are made between only hubs or only nodes. Refer to the manual of each network device because the specification may differ by the device. Select generally used RJ-45 type plugs for the connectors of both ends. STP Cables In environments with much noise, use shielded twisted pair (STP) to reduce the effects of noise. However, conditions of usage may differ by the network device; use the cable on your own authority referring to the manual of the network device in use. Optical Fiber Cables It is recommended to use this type of cable when you lengthen distances, wire between separate buildings or use the device in the environment with much noise. The following LAN standards are provided for the use of optical fiber cables: 10BASE-FL, 100BASE- FX, 1000BASE-SX and 1000BASE-LX. Each standard defines the type of optical fiber and maximum distances. For the detailed specification, refer to manuals of the network device in use or manuals of IEEE802 or the standard itself. Media converters having optical interfaces or switching hubs supporting optical interfaces are needed because optical interfaces have not been mounted on FCNs/FCJs. Specifications of Major Cables Specifications of major network cables are shown below.

Installing Network Devices Power Dispatching When the power of one of network devices such as a hub is shut down, the entire communications of all devices attached to the network device stop. You should determine the power routing considering the scope of effects as described above. In the case where the reliability is severely required, it is recommended to prepare backup powers, or duplex network devices, each of which be powered via separate routing. Selecting Devices As far as possible, install network devices including a hub for each area, with minimum number of wirings among the area. Choose network devices according to the purpose, among several types e.g., devices for mounting to a 19-inch rack, to a desktop or to a wall. For the number of ports, it is recommended to choose a hub with more ports than you actually use at present, in consideration of the future expansion or the use as a port for monitoring when failures will occur. According to the environment (temperature, moisture, dust, noise, etc.) where the network device is installed, select the optimum one. Checking LED Display LEDs for checking statuses are implemented on each network interface of FCN/FCJ. Generally, LEDs are also implemented on ports of network adapters and network devices. When finished connecting the cable, you need to check if the Link light flashes, and Act, Send, Rcv and other lights flash while communication is performed. Table Network Interface LEDs of FCN/FCJ Colors Names Contents Yellow LINK Connection is normal Orange ACT Send/receive

For the LED displays of hubs or network adapters, refer to the manual of each device since the number and role of each LED differ by the device. Communication Test When you finished setting the device and connections, check if the communication is normally established by executing Ping command or other methods. Replacing Network Devices You can replace network devices such as hubs, cables or routers on-line. The communication stops while the device is replaced; however, it starts again when you connect the cable after the replacement. If the control network is duplexed, the network has the feature to switch communication paths automatically, enabling to change the device maintaining the communication. Please follow the right steps to change the device checking the messages notifying the failure or the recovery of the network.

Restrictions on total distances of networks According to the 1000BASE-T/100BASE-TX/10BASE-T standards, cables of up to 100 meters can be used. It is possible to extend the total distance via hubs on many levels with cascade connections. However, if a repeater hub is used, the following restrictions are applied to total distances: • If a repeater hub is used with 100BASE-TX cables The total distance is up to 205 meters, with up to 2 levels in cascade connections, within 100 meters for cable lengths between devices and within 5 meters for cable length between hubs (IEEE802.3u Standard). • If a repeater hub is used with 10BASE-T cables: The total distance is up to 500 meters, with up to 4 levels in cascade connections and within 100 meters for cable lengths between devices. If the 1000BASE-T is used, or a network requires a total distance exceeding these restrictions, use switching hubs or routers to configure such a network.

1.5 Communication Protocols This chapter explains the communication protocols used in the devices that configure STARDOM system.

STARDOM system uses Ethernet for control networks and the upper control system information network. For network layers and transport layers, the industry-standard TCP/IP is employed. Communications between VDS Data Server and FCN/ FCN-RTU/FCJ For communications between VDS data server and FCN/FCJ, a communication protocol based on Fast Ethernet and TCP/IP is employed. Time Synchronization FCN/FCJ has SNTP client functions and time adjusting functions as standard features, enabling to synchronize times among nodes. In the FCN-500, it is possible to execute the SNTP function as a standard feature. In the FCN-100 and FCJ, it is possible to execute the SNTP function by installing a time synchronization server portfolio. Utility Communications Configuration tools for defining FCN/FCJ or field network devices and designing control logics, establish communications with FCN/FCJ using dedicated protocols. More specifically, the tools download definitions of devices defined on Resource Configurator or other configuration tools, download control logics created on Logic Designer, and execute maintenance communications of control logics using Logic Designer. Communications between VDS Data Server and VDS HMI Server OPC-DA is employed for communications between VDS data server and VDS HMI server, or VDS data server and other computers. Communications between VDS HMI Server and HMI Client HMI client does not require any software other than Java Runtime Environment. For communications between HMI client and VDS HMI server, HTTP uses only. Network Features of FCN/ FCN-RTU/FCJ FCN/FCJ normally supports the protocols needed to communicate with open network devices: receiving and sending mails, HTTP, FTP, TELNET, and other protocols.

2. Network Features of STARDOM This chapter explains basic network features of STARDOM system.

2.1 Varieties of Basic Configurations Several examples of basic network configurations are shown in this section. Small Two-layered System (Standard) In this type of network, the control system information network connecting HMI clients and the broadcast domain of the control network connecting controllers are separately configured. This is one of the standard system configurations of STARDOM. Generally, two network adapters are mounted on a VDS data server; one is used for control network, and the other is used for control system information network. Upper Computer HMI HMI

For routing, use VDS as a router or set a local router between the control system information network and the control network. In consideration of the features of a control network, performing real-time and reliable communications, you should not include frames unnecessary for the network by routing.

Medium Scale Two-layered System This medium scale system consists of several VDSs. A VDS HMI server collects and consolidates data from VDS data servers, giving these data to HMI clients. You can implement VDS HMI data server functions on one of VDS data servers.

In the following cases, it is recommended to connect several VDS data servers. • Many controllers to be connected • Many data points • Controllers are distributed in remote areas

2.2 Network Basic Definitions (IP Address Settings) This section explains IP address settings of FCN/FCJ and VDS connected to control networks of STARDOM.

Rules for IP Address Allocation STARDOM’s control networks can take two types of configurations: single and duplex. Moreover, CPUs can be duplexed in the FCN500 and FCN-100, where an IP address is allocated to each of the duplexed CPUs. The rules for IP address allocation in each configuration are described below:

TIP Not add 0 to the top of the IP address. When you add 0, it is treated as octal. It becomes the error or the wrong address. It is checked closely with Windows 10 and Windows 7. Example, "192.168.01.08" is an error. "192.168.01.011" is recognized as "192.168.1.9".

Single Network Configuration [If the FCN-500 and FCN-100 does not use a configuration of duplexed CPUs, and FCN-RTU] There are no restrictions on the IP addresses that can be used.

[If the FCN-500 and FCN-100 uses a configuration of duplexed CPUs] Arbitrary IP addresses can be set to both the control side CPU and the standby side CPU of the FCN-500 and FCN-100. Use the Resource Configurator and specify an IP address for the control side CPU. Then, select the “Detail…” button of the “General” tab under “CPU Module”, remove the tick for “Auto” in the IP address checkbox for the standby side CPU, and explicitly specify an IP address for the standby-side CPU.

TIP • If there are multiple control system network domains, change the respective network addresses. e.g. Domain 1: 192.168.0.0 Domain 2: 192.168.1.0 • When the FCN has duplexed CPUs, the IP address of the standby side CPU is, by default, automatically allocated on the basis of the IP address of the control side CPU according to certain rules as explained in the “IP Address Decision Rules” section in “2.6 Duplexing Control Network” Therefore, if the default IP address of the standby side CPU is used as it is, specify a value for the IP address of the control side CPU in such a way that the value will not contradict the IP address of the standby side CPU. In a single network configuration, the default value for the IP address of the standby side CPU can be changed by the Resource Configurator. Therefore, if you wish to designate an arbitrary IP address for the control side CPU, change the default value for the IP address of the standby side CPU, too.

TI 34P02K25-01E Jun. 6, 2018-00

<2. Network Features of STARDOM> 24

Duplexed Network Configuration [If the FCN-500 and FCN-100 don’t use a configuration of duplexed CPUs] Use class C private addresses of IPv4. The setting procedures of IP addresses are explained as follows:

• Set an address in the range of 192.168.x.1-192.168.x.254, in which “x” is should be at three intervals in the range of 0-252. • Set a subnet mask to 255.255.255.0. • Specify the address of a default router connected to the control network for the default gateway. If you do not connect a router to the control network, it is not needed to specify the address. • Example of IP address settings VIP address: 192.168.3.1 Subnet mask: 255.255.255.0 Default gateway: none This setting reserves 192.168.4.1 and 192.168.5.1 for physical IP addresses.

[If the FCN-500 and FCN-100 use a configuration of duplexed CPUs] Use IP addresses according to the same rule as in the case of not using a configuration of duplexed CPUs. However, IP addresses must be within the range of 192.168.x.1 – 192.168.x.126. An IP address for the standby side CPU will be automatically allocated within the range of 192.168.x.129 – 192.168.x.254.

TIP • When several network domains exist, different addresses should be set to each of them. e.g. Domain 1: 192.168.0.0 Domain 2: 192.168.3.0 • It is recommended to define each IP address allocation depending on the device; for example, the controller's IP addresses begin from 192.168.x.1 and the VDS's IP addresses begin from 192.168.x.101, etc. • In a duplexed network, IP addresses for PIP-A, PIP-B and the standby side CPU cannot be changed because they are automatically allocated. • The FCN/FCJ allows a configuration of separated networks (in which two network interfaces are used as separate networks). However, in this separated network configuration, use the same concept as in the case of a single network configuration to decide IP addresses. • VIP means a virtual IP address. For details, see “Various IP Addresses” in “2.6 Duplexing Control Network.”

Network Configuration of the FCN/ FCN-RTU/FCJ The FCN-500 (with NFCP501 CPU module), FCN-100 and FCJ have two network interfaces on each CPU. These network interfaces can take the following three network configurations: • Single network configuration (in which network interface 2 is not used) • Duplexed network configuration • Separated network configuration (connected to two separated networks)

The FCN-500 (with NFCP502 CPU module) has four network interfaces on each CPU. These network interfaces can take the following four network configurations: • Single network configuration (in which network interface 2/3/4 are not used) • Duplexed network configuration (network interface 1 and 2) • Separated network configuration (connected to four separated networks) • Duplexed network (network interface 1 and 2) and Separated network (network interface 3 and 4) configuration

The FCN-RTU has one network interface on the CPU, It’s a single network configuration. And a single CPU use only.

Each configuration is set in the “Network Group” combo box of the “Basic Configuration” tab in the CPU Module Setting window of the Resource Configurator. The overview of how each network configuration works is described below:

Separated Network Configuration In a separated network configuration, network interface 1 of the FCN/FCJ is used for a control network, while network interface 2 (network interfaces 2/3/4 in NFCP502 only) is used for a network independent of the control network: for example, network interface 2 can be connected to a dedicated PLC network by PLC communication. However, when connecting PLCs or PCs to the FCN/FCJ via a network, the network must be configured to avoid having influences on FCN/FCJ control by communication load lead from other devices.

SEE ALSO Refer to “2.7 Cautions for Network Configuration” when connecting devices other than VDS and FCN/FCJ devices to the network.

This network configuration has the following restrictions: • No routing can be performed between network interface 1 and network interface 2 (network interface 1/2/3/4 in NFCP502 only). • With respect to FCN/FCJ communications using the communication function block, network interface 1 allows communications via routers (communications to separate subnets), while network interface 2 does not. (FCN/FCJ: Only for System R1.80 or Earlier) Separated networks are configured as follows:

IP Address Settings to FCN/FCJ You can configure IP addresses to an FCN/FCJ on Resource Configurator as follows:

1. Connect a PC on which Resource Configurator is installed to FCN/FCJ, and start Resource Configurator on the PC. Resource Configurator and FCN/FCJ must be connected on the same broadcast domain. The IP addresses cannot be set via a router.

2. To the network interface1 of FCN/FCJ, connect an Ethernet cable. IP addresses cannot be correctly configured if you use the interface2.

3. Start FCN/FCJ in IP addresses setting status. If the LED is flashed as in the table below, FCN/FCJ is in that status. Table Flashing Statuses of LED LEDs Statuses HRDY High speed flashing CPURDY Low speed flashing CTL Lighted out

TIP In FCN-500 and FCN-RTU, IP addresses are written to an on-board flash memory on CPU module. An CPU module, to which IP addresses has never been configured, becomes IP address setting status automatically when powered on. If an IP address is reconfigured to an CPU module that already has IP addresses, reboot from the maintenance window on a Web browser in IP addresses setting status, or press a shutdown switch of FCN-500 or FCN-RTU. For the detailed sequence, see the corresponding manuals or online-help files. In FCN-100 and FCJ, IP addresses are written to an FCN/FCJ system card (Compact Flash). An FCN/FCJ system card, to which IP addresses has never been configured, becomes IP address setting status automatically when powered on. If an IP address is reconfigured to an FCN/FCJ system card that already has IP addresses, reboot from the maintenance window on a Web browser in IP addresses setting status, or press a shutdown switch of FCN/FCJ. For the detailed sequence, see the corresponding manuals or online-help files.

4. Select [File] and then [Set IP Address] from the menu of Resource Configurator to display the IP address setting dialog.

5. On the IP address setting dialog, configure IP addresses and subnet mask corresponding to the displayed MAC address. Configure a default gateway as necessary. When you finished all settings, click [OK].

TIP The IP address setting window of Resource Configurator is displayed using the BOOTP protocol; if FCN/FCJ with no IP addresses is connected, Resource Configurator displays MAC address of the FCN/FCJ on its IP address setting window. The duplicated IP addresses due to incorrect-inputs must be carefully avoided.

With these settings, the IP address settings of the single control network configuration have been completed. If you are to have the duplexed or separated control network configuration, perform the following settings: 6. Use the Resource Configurator to connect to the FCN/FCJ and configure a control network. For detailed operation methods, see the “Network functions” section on the [FCN/FCJ Setting] – [CPU Module Setting] page of the Resource Configurator’s online help and set a duplexed or separated network configuration.

IP Address Settings to VDS You will set IP addresses to a PC onto which you will mount functions of VDS (VDS data server, VDS HMI server, and HMI client).

Configure the same network addresses of FCN/FCJ to the network interface of VDS data server connected to the control network. If you do not use the duplexed control network function, configure the IP addresses according to the Windows standard procedures. VIP (Virtual IP Address) Settings If you use the duplexed control network function, you need to start FCN/FCJ connection setting tool to configure virtual IP addresses (VIP).

Creating HOSTS Files The correspondences between IP addresses connected to a control network and host names are managed in HOSTS files. The HOSTS files are referred for host name resolution while communicating.

TIP HOSTS files are used for managing each node with the logical name. If you set nodes to be managed with only IP addresses, it is possible to omit the procedure to create HOSTS files.

VDS HOSTS files of VDS exist in the following directory. %windir%\system32\drivers\etc Using editors like notepad, input host names and IP addresses of all nodes connected to the control network.

2.3 Communication Performances A STARDOM system collects and monitors data from controllers via networks. Therefore, it is important to estimate communication performances of the network. This chapter details the approximate scale of a standard STARDOM system and how to estimate communication loads.

Standard System Scale The approximate calculation of data (data object number, data point number) and communication time (data acquisition time, starting time) are indicated in the table below: Table Approximate Traffic Types Items Specifications Amount of data per FCN/FCJ At most 3200 points/sec At most 400 objects/sec, Data number per VDS data server At most 6400 points/sec VDS data server Communication time per object and FCN/FCJ At most 50 ms (accessing a single object, 100 Mbps) Communication time per 100 objects At most 400 ms (accessing several objects, 100 Mbps) At most 400 objects/sec, Amount of data per VDS data server At most 6400 points/sec VDS data server At most 1600 objects/sec, and VDS HMI server Amount of data per VDS HMI server At most 25600 points/sec Communication time per object 100 ms or less

VDS HMI server HMI clients per VDS HMI server At most 50 clients and HMI client Communication time per object 100 ms or less

Necessity of Network Load Calculation It is necessary to calculate network load factor accurately when you construct a large- scale system or employ low band including wide area network as the communication infrastructure. For a small high-speed network system, the accurate calculation is not always necessary, however, it is recommended to estimate approximate network load factor.

Estimating Network Load It is possible to estimate network load by calculating the entire traffics passed through hubs, nodes, and ports of hubs (see the figure below). It is necessary to estimate the amount considering features of two types of hubs: switching hubs and repeater hubs. A repeater hub forwards frames received from a port to all ports; therefore, traffics received by and forwarded to all ports of hubs should be calculated. On a switching hub, a unicast communication between two ports is not forwarded to other ports. As indicated in the figure below, calculate traffics that may be passed through each port of hubs. In a general configuration, it is presumed that communication loads center on the port connected to VDS data server or the port connecting switching hubs.

Reducing Network Load If it becomes clear that the network is overloaded as the result of calculating network load factor, the following methods can reduce the load. • Leave only data needed to be referred and window needed to be displayed • Lengthen the interval of updating data • Employ a switching hub and configure the system so as to minimize collisions on communications between devices • Configure the system so as to minimize communications between switching hubs • Employ broadband network configurations for the loaded part of the network; e.g. supporting gigabit, or employing port aggregation (a function to use multiple ports for the connection of two hubs and to enable high throughput using them as one network connection). • Divide a broadcast domain using the VLAN or Layer3 switch. • Use a switching hub with higher data forwarding performance. • Distribute the loads to several VDS data servers. • Distribute the loads to several FCNs or FCJs.

Network Load Factor Calculation (Steady State) A network load factor can be calculated from total traffic per second. R (%) = 100 * (VDSD + OPCD + HMID + FCXD + PLCD + ETCD) / A ...... (1) The steady-state network load factor (R) should fall within the following range. R (%) < 20 ......

Network Load Factor Calculation (Startup) VDS and HMI perform communications differently at startup and at steady state. In some cases, a startup can consume longer time; you should additionally calculate each starting time. Starting Time of VDS Data Server This subsection explains the calculation of communication time, through calculating traffic occurs when the first communication starts (a session is established) between FCN/FCJ and VDS data server. The communication to establish a session includes uploading time of database (ADLST.csv) for accessing data, and reading time of messages. The communication time can be calculated as follows: VDSST [s] = (SesOp + DataNum * 100 + MsgNum * 160 [byte]) / A ...... (20) SesOp: time for establish connections DataNum: number of data items MsgNum: number of messages per second A: transmission rate on a line (byte/sec) To simplify, it is assumed that the amount of database per a point of data be 100byte and the overhead to communicate a message be 160byte. While starting up, VDS data server reads all messages managed by FCN/FCJ. When calculating communication time, you need to consider that VDS data server reads off the maximum number of messages (MaxMsgNum). Starting Time of HMI Client Through calculating traffic occurs during the time between starting of HMI client (by starting of VDS Viewer) and being ready for monitoring data on HMI, the communication time can be calculated. Actually, in addition to the communication time, the time for authorizing each logon and displaying graphics are added. The communication time should be considered as an approximate guide for starting time of HMI client. The communication time can be calculated as follows: HMIST [s] = (HMID(STT) + HMID(APP) + HMID(GRA) ) / A + HMID(INT) ...... (22) HMID (STT) HMID (STT) is the traffic on HMI client from invoking a server on a VDS Viewer to logging on. HMID (STT) = 20 [kbyte] ...... (23) HMID (APP) HMID (APP) is the traffic that occurs when displaying a graphic window only for the first display of the window. HMID (APP) = 500 [kbyte] ...... (24) HMID (GRA) HMID (GRA) is the size of a graphic file (.sgr). For a typical graphic window, the following should be assumed as an approximate value. HMID (GRA) = 100 [kbyte] ...... (25)

TI 34P02K25-01E Jun. 6, 2018-00

<2. Network Features of STARDOM> 44

HMID (INT) HMID (INT) is the time from the completion of downloading a graphic display program till the completion of a display. While this time depends not on communication time but on the PC’s CPU performance, the following should be assumed as an approximate value: HMID (INT) = 20 [sec] ...... (26) If displayed again using the same Viewer, the following should be assumed as an approximate value: HMID (INT) = 5 [sec]

2.4 Security This chapter explains the security features on STARDOM networks.

Security on Control Networks For communications between VDS data server and controllers, the original idea is applied to the design of session management and database, to prevent wiretapping activities, passing-off, and tampers from outside of the networks.

Security Features between VDS Data Server and VDS HMI Server For communications between VDS data server and VDS HMI server, DCOM is employed ensuring security functions working with the Windows-system user management.

SEE ALSO For the detailed information on security functions, see "VDS/ASTMAC Security"(IM 34P02D12-01E).

Security at Wide Area Network Considering the features of HMI client that can be set on remote offices via a LAN or WAN, it is furthermore important to ensure security functions for this type of network. Between VDS HMI server and HMI client, an authorization was given by user name and password at logging on of the user. The typed password is encrypted before transmission. If you use a WAN, the security control described above is insufficient. You should connect routers supporting VPN, which allows communication frames to be encrypted, preventing wiretapping activities, tampers and other accesses from outsiders. In addition, a firewall should be implemented between external networks and internal networks to minimize accessing from outside; basically, only HTTP communications to HMI server are authorized. Counter measure by VPN and/or firewall is necessary for remote direct access to FCN/FCJ by InfoWell package and remote maintenance purpose to reduce risk.

SEE ALSO For cases of installing firewalls and VPN routers, see "3.12 Operation with Remote HMI".

Features Duplexing of STARDOM control network is attained by general-purpose network adapters, device drivers, network devices (switch, cable, etc.) based on TCP/IP protocol. Each node has several network interfaces and controls communication paths between them by routing table. For applications, the duplexed network is invisible because they communicate using each node name or IP address. It is outstanding for short switching time between network paths and seamless switching for applications. In addition, you can connect devices that do not have the duplexed network function like PLCs to the duplexed control network.

Two Networks In duplexed STARDOM network, there are two routes for nodes engaged in communications: the above-mentioned Network-A and Network-B. Two respective networks are on an equal basis. Which network is used for data communications is determined in each node (peer-to-peer) engaged in communications. Therefore, if we focus on a certain VDS, there can be a situation in which Network-A is used between the VDS and a controller, while Network-B is used between the VDS and another controller. However, if a node is activated in a situation where both network cables of the node are properly connected to networks, Network-A is generally used. Single Interface Device A single interface device is the node that has only a single network interface for control networks or does not have STARDOM duplexed network function. Dual Interface Devices Dual interface device is the node that has dual network interfaces for control networks and STARDOM duplexed network function. It refers to FCN/FCJ and VDS which has configured duplexed network function. Interface A The first network interface on each node is referred to as interface A. Network interface of a single interface device is interface A. On VDS, the network interface to which VIP and PIP-A are configured is interface A. On FCN/FCJ, network interface1 is interface A. Interface B The second network interface on each node is referred to as interface B. Network interface of a single interface device does not have interface B. On VDS, the network interface to which PIP-B is configured is interface B. On FCN/FCJ, network interface2 is interface B.

Various IP Addresses For realizing the duplexed network, it is necessary to configure virtual IP addresses and physical IP addresses for nodes. An application simply recognizes virtual IP addresses. Physical IP addresses are used for maintenances of communication paths through the duplexed network function. If you do not use the duplexed network function, the distinction between virtual and physical IP addresses is not needed; replace virtual IP addresses to IP addresses for understanding this manual. Virtual IP Address (VIP) VIP is the typical IP address defined by a node. Resource Configurator defines this IP address. General applications communicate using node names and VIP. A VIP is configured for a network interface for which PIP-A is configured.

TIP If the control right is alternated when CPUs are duplexed in the FCN, VIPs move from the original control side to the new control side in conjunction with the control right. Accordingly, general applications are not required to duplex the CPU of FCN.

Physical IP Address (PIP) PIP is the IP address configured in network interfaces and created automatically based on rules defined in advance. Physical IP Addresses A (PIP-A) PIP-A is the IP address configured to interfaces on interfaces A sides. PIP-A of each node is set so as to be identical network address. General applications do not realize this address. Physical IP Addresses B (PIP-B) PIP-B is the IP address configured to interfaces on interfaces B side. PIP-B of each node is set so as to be identical network address and different from the one of PIP-A. General applications do not realize this address.

IP Address Decision Rules Physical IP addresses (PIP-A, PIP-B) when FCN/FCJ networks are duplexed or the IP address of the standby side CPU when CPUs are duplexed in the FCN are decided according to certain rules, depending on the virtual IP address (VIP) to be set by a user to the FCN/FCJ. The IP calculation rules are described below. Necessary Information Prior to Deciding IP Addresses Although IP addresses are usually expressed as four decimal numbers such as 192.168.1.1, they are internally treated as 32-bit binary numbers. For the notation of 192.168.1.1, a 32-bit number is divided into four 8-bit numbers from the top, each of these being converted into decimal numbers and connected with a dot (.). This address becomes C0A80101 if expressed in hexadecimal notation. An IP address is divided into a network address and a host address according to its subnet mask.

TI 34P02K25-01E Jun. 6, 2018-00

<2. Network Features of STARDOM> 63

A subnet mask is set as 255.255.255.0. A network address is decided by an IP address and a subnet mask are respectively converted into binary numbers and a “logical AND” of each bit is performed. If an IP address is 192.168.1.1 and a subnet mask is 255.255.255.0, they are converted into hexadecimal numbers of C0A80101 and FFFFFF00 respectively. Thus, the network address is C0A80100 = 192.168.1.0. A host address is an address after a network address. If an IP address is 192.168.1.1 and a subnet mask is 255.255.255.0, it is 01 as a hexadecimal number and 1 as a decimal number. Physical IP addresses (PIP-A, PIP-B), when FCN/FCJ networks are duplexed, or IP addresses of two CPUs, when CPUs are duplexed, are decided by using network addresses and host addresses of the virtual IP address (VIP). Rules for Deciding the PIP of a Single CPU and the Duplexed Network Configuration of an FCN/FCJ In a single CPU and duplexed network configuration of an FCN/FCJ, physical IP addresses (PIP-A, PIP-B) of FCN/FCJ are decided on the basis of the virtual IP address (VIP) according to the following rules: [PIP-A] • Network address: a value obtained by adding 1 to the VIP’s network address • Host address: the same value as the VIP’s host address [PIP-B] • Network address: a value obtained by adding 2 to the VIP’s network address • Host address: the same value as the VIP’s host address If these rules are applied to a VIP of 192.168.0.1 and a subnet mask of 255.255.255.0, hexadecimal network addresses are C0A80100 and C0A80200 for PIP-A and PIP-B respectively, while hexadecimal host addresses are 01 for both PIP-A and PIP-B. Their IP addresses are shown in the table below: Table IP Addresses when an FCN/FCJ Network is Duplexed IP Address (Hexadecimal) VIP 192.168.0.1 (C0A80001) PIP-A 192.168.1.1 (C0A80101) PIP-B 192.168.2.1 (C0A80201)

TIP • In a duplexed network configuration, use class C private addresses of IPv4 and set a subnet mask to 255.255.255.0. • In a duplexed network configuration, PIP-A/B cannot be changed via the Resource Configurator. Therefore, set the values to a VIP so that no contradictions will occur to PIP-A/B in the above rules.

Rules for Deciding the IP Address of a Duplexed CPU and a Single Network Configuration of FCN-500 and FCN-100 In a duplexed CPU of FCN-500 and FCN-100 and single network configuration or a separated network configuration of an FCN, the IP address of the standby side CPU is decided on the basis of the IP address of the control side CPU according to the following rules: • Network address: the same value as the network address of the control side CPU • Host address: a value obtained by setting the most significant bit of the host address of the control side CPU as 1 If these rules are applied to an IP address of 192.168.1.1 with a subnet mask of 255.255.255.0 for the control side CPU in a single network configuration, the network address remains C0A80100 and the host address is 81 (10000001 in the binary notation) in the hexadecimal notation with respect to the IP address of the standby side CPU. Thus, the IP address of the standby side CPU is C0A80181 = 192.168.1.129. IP addresses of control side/standby side CPUs are shown in the table below: Table IP Addresses of Control Side/Standby Side CPUs IP Address of Control Side CPU (Hexadecimal) IP Address of Standby Side CPU (Hexadecimal) 192.168.1.1 (C0A80101) 192.168.1.129 (C0A80181)

In this configuration, the IP addresses of two duplexed CPUs are alternated every time they switch from the control side to the standby side and vice versa.

TIP • In a single network configuration or in a separated configuration, there is no distinction between the virtual IP address (VIP) and the physical IP address (PIP). IP addresses are simply treated as those of the control side/standby side. • The IP address of the standby side CPU when CPUs are duplexed in the FCN-500 and FCN-100 is, as mentioned above, the value obtained by setting the most significant bit of the host address of the control side IP address as 1. For the IP address of the control side CPU, therefore, use a host address whose most significant bit is 0. For example, if a subnet mask is 255.255.255.0 and 1 to 126 (01 to 7E in the hexadecimal notation) is used for the host address of the control side CPU, the host address of the standby side CPU becomes 129 to 254 (81 to FE in the hexadecimal notation). • In a single network configuration or in a separated configuration, the standby side CPU’s IP address decided according to the above rules can be changed via the Resource Configurator.

Rules for Deciding the IP Address of a Duplexed CPU and a Duplexed Network Configuration of FCN-500 and FCN-100 (FCN/FCJ: System R1.85 or Later) In a duplexed CPU and a duplexed network configuration of FCN-500 and FCN-100, the PIP-A/B of control side/standby side CPUs are determined on the basis of the FCN’s VIP according to the following rules: [PIP-A of the control side CPU] • Network address: a value obtained by adding 1 to the VIP’s network address • Host address: the same value as the VIP’s host address [PIP-B of the control side CPU] • Network address: a value obtained by adding 2 to the VIP’s network address • Host address: the same value as the VIP’s host address [PIP-A of the standby side CPU] • Network address: a value obtained by adding 1 to the VIP’s network address • Host address: a value obtained by setting the most significant bit of the VIP’s host address as 1 [PIP-B of the standby side CPU] • Network address: a value obtained by adding 2 to the VIP’s network address • Host address: a value obtained by setting the most significant bit of the VIP’s host address as 1 As described above, host addresses of the PIP-A/B of the standby side CPU are the values obtained by setting the most significant bit of the VIP’s host address as 1. If this is applied to a VIP of 192.168.1.1 with a subnet mask of 255.255.255.0 (the host address is 01 in the hexadecimal notation), the PIP-A/B host addresses of the standby side CPU become 81 in the hexadecimal notation (10000001 in the binary notation) or 129 in the decimal notation. If these rules are applied to a VIP of 192.168.0.1 with a subnet mask of 255.255.255.0, PIP/A and PIP-B are decided as in the table below: Table IP Addresses of Control/Standby side CPUs IP Address of the Control side CPU IP Address of the Standby side CPU

(Hexadecimal) (Hexadecimal) VIP 192.168.0.1 (C0A80001) < to be allocated to the control side CPU > PIP-A 192.168.1.1 (C0A80101) 192.168.1.129 (C0A80181) PIP-B 192.168.2.1 (C0A80201) 192.168.2.129 (C0A80281)

In this configuration, VIP, PIP-A and PIP-B allocations of two duplexed CPUs are changed every time CPUs switch from the control side to the standby side.

TIP • In a duplexed network configuration, use class C private addresses of IPv4 and set a subnet mask to 255.255.255.0. • The IP address of the standby side CPU when CPUs are duplexed in FCN-500 and FCN-100 is, as mentioned above, the value obtained by setting the most significant bit of the VIP’s host address as 1. For the VIP, therefore, use a host address whose most significant bit is 0. A VIP's host address uses the value from 1 to 126 (01 to 7E in the hexadecimal notation), and a PIP-A/B's host address of the standby side CPU becomes 129 to 254 (81 to FE in the hexadecimal notation). • In a duplexed network configuration, PIP-A/B cannot be changed via the Resource Configurator. Therefore, set the values to a VIP so that no contradictions will occur with PIP-A/B in the above- mentioned rules. • FCN/FCJ: For system R1.85 or later, PIP is calculated automatically by the control side CPU/standby side CPU. FCN/FCJ: For system R1.80 or earlier, PIP is calculated automatically by the position of the implemented CPU (left side/right side).

Important

Rules for IP address allocation differ between the FCN/FCJ system R1.80 or earlier and the system R1.85 or later. Accordingly, there is no communication compatibility between the FCN/FCJ system R1.80 or earlier and the system R1.85 or later. Therefore, if you use a FCN/FCJ system R1.85 or later, use the following versions. • VDS/ASTMAC: R5.40.10 or later • FCN/FCJ: R1.85.01 or later • Duplexed network program for FCN/FCJ OPC server: R1.85.01 or later

Rules for Deciding the IP Address of a Duplexed CPU and a Duplexed Network Configuration of an FCN-100 (FCN/FCJ: System R1.80 or Earlier) In a duplexed CPU and a duplexed network configuration of an FCN-100, the PIP-A/B of left/right CPUs are determined on the basis of the FCN’s VIP regardless of the control side/standby side according to the following rules: [PIP-A of the left CPU] • Network address: a value obtained by adding 1 to the VIP’s network address • Host address: the same value as the VIP’s host address [PIP-B of the left CPU] • Network address: a value obtained by adding 2 to the VIP’s network address • Host address: the same value as the VIP’s host address [PIP-A of the right CPU] • Network address: a value obtained by adding 1 to the VIP’s network address • Host address: a value obtained by setting the most significant bit of the VIP’s host address as 1 [PIP-B of the right CPU] • Network address: a value obtained by adding 2 to the VIP’s network address • Host address: a value obtained by setting the most significant bit of the VIP’s host address as 1 As described above, host addresses of the PIP-A/B of the right CPU are the values obtained by setting the most significant bit of the VIP’s host address as 1. If this is applied to a VIP of 192.168.1.1 with a subnet mask of 255.255.255.0 (the host address is 01 in the hexadecimal notation), the PIP-A/B host addresses of the right CPU become 81 in the hexadecimal notation (10000001 in the binary notation) or 129 in the decimal notation. If these rules are applied to a VIP of 192.168.0.1 with a subnet mask of 255.255.255.0, PIP/A and PIP-B are decided as in the table below: Table IP Addresses of Right/Left CPUs IP Address of the Left CPU (Hexadecimal) IP Address of the Right CPU (Hexadecimal) VIP 192.168.0.1 (C0A80001) < to be allocated to the control side CPU > PIP-A 192.168.1.1 (C0A80101) 192.168.1.129 (C0A80281) PIP-B 192.168.2.1 (C0A80201) 192.168.2.129 (C0A80381)

In this configuration, VIP allocations of two duplexed CPUs are changed every time CPUs switch from the control side to the standby side and vice versa. However, PIP-A and PIP-B are fixed for use without being changed.

Internal Operations in the Duplexed Network Function This section explains the internal operations in the duplexed network function of STARDOM. Network Status Table (NSTBL) Network functions of FCN/FCJ or VDS connected to a control network manage statuses of network interfaces (network statuses) of each node as a network interface status table (NSTBL). For nodes with the duplexed network function, information of standby side network interface is also managed. All VDSs and FCNs/FCJs have NSTBLs used for algorisms of network failure, switching between network paths, network recovery, etc. NSTBL contains the following information: Table Example of Network Status Table Device Network Path Information VIP PIP-A PIP-B Index Network-A Network-B 1 192.168.0.1 192.168.1.1 192.168.2.1 OK OK 2 192.168.0.2 192.168.1.2 192.168.2.2 OK OK 3 192.168.1.130 192.168.2.130 OK OK

Diagnostic Communication Frame Duplexed network function of FCN/FCJ or VDS connected to a control network performs periodically multicast transport of network interface statuses as diagnostic communication frames, for updating NSTBL. The diagnostic communication frames store NSTBL managed by the node. A node that received diagnostic communication frames of other node updates its NSTBL based on the information stored in that frame. Diagnostic communication frames are transmitted by each dual interface individually.

The default diagnostic communication interval is 500ms. The two consecutive failures of diagnostic communications are recognized as a failure, making switching time 1000 to 1500 ms when diagnostic communication interval is 500ms. Diagnostic communication frames are sent in conjunction with the number of duplexed devices (such as FCNs or VDSs) to a network and are received by the devices. These devices process frames every time they are received: the greater the number of duplexed devices, the greater the reception processing of diagnostic communication frames, thereby increasing the load on CPUs. Therefore, if the number of duplexed devices is substantial, the transmission cycle of diagnostic communication frames should be extended. The table below provides a guide for the number of devices and diagnostic cycles. Table Guide for the Number of CPUs and the Diagnostic Cycles Number of CPUs Diagnostic Cycle (msec) Remarks Up to 12 500 Default value for diagnostic cycles 13 to 25 1,000 26 to 37 1,500 38 to 50 2,000 51 to 62 2,500 63 to 75 3,000 76 to 87 3,500 88 to 100 4,000 101 to 112 4,500 113 to 125 5,000 126 to 137 5,500 138 to 150 6,000 151 to 162 6,500 163 to 175 7,000 176 to 187 7,500 188 to 200 8,000 201 to 212 8,500 213 to 225 9,000 226 to 237 9,500 238 to 248 10,000

Note: The number of CPUs is the total number of FCNs/FCJs/VDSs in a network which uses the network duplex function (if CPUs of an FCN are duplexed, the number of CPUs is 2).

SEE ALSO For the communication load of diagnostic communication frames, see "2.3 Communication Performances".

Network Failure A network failure is the status where one of dual network paths is unavailable. The network failure is managed per node. If diagnostic communication frames cannot be received from a node, the network path to the node is recognized to be failed, which is notified to the operator as a message. The cause of failures can be as follows: failure of network interface of own node, failure of network interface of the destination node, failure of network devices (hubs and cables) on the network path between the two nodes, communication jamming due to the temporary noises, etc. Switching between Network Paths If a network failure to a node is detected, Routing Table is automatically changed, switching immediately over another of dual network paths. Network Recovery The node that detects a network failure continues to monitor the failed network. If the recovery is detected, the message notifying the network recovery is sent to the operator.

Supporting Duplexed CPU of FCN-500 and FCN-100 When a control side CPU (controlling the system) of FCN-500 and FCN-100 fails, the control right is moved to a standby side CPU (: this side always equalizes with the control side and in waiting status to receive the control right in the case that the control side fails). The equalization between the control side and standby side is performed via the control network. The CPU that newly acquires the control right continues to communicate, by succeeding the network information (virtual IP addresses, host names, etc.) of the CPU that previously had the control. Other nodes that had been communicated with FCN-500 and FCN-100 whose CPU was switched, detect the switching between network paths, switching over another path automatically. Communication of the control network will stop for 1 to 3 seconds. This function ensures operations for applications of the nodes that had been communicated with the FCN-500 and FCN-100. Host Name and IP Address A host name and IP address (VIP) with duplexed CPU is consistent and can be recognized as a single device for applications of a client (e.g. VDS). When the switching takes place between CPUs in FCN-500 and FCN-100, the VIP is also moved to the CPU that takes control immediately. Standby Side CPU Network Interface Status The network interface statuses of the standby side CPU are always checked and the results are reflected to NSTBL.

“Duplexing” Setting and “Separated” Setting When duplexing communications of FCN/FCJ using an application, the network can be configured in the following two ways.

• Duplexed network configuration • Separated network configuration

For STARDOM, it is recommended to use the “duplexed network function provided on STARDOM” and “duplexed network configuration” that allows for “duplexing communications using an application.”

SEE ALSO For the “duplexed network configuration” and “separated network configuration,” see “Duplexed Network Configuration” and “Separated Network Configuration” sections in “2.2 Network Basic Definitions (IP Address Settings).”

2.7 Cautions for Network Configuration

Connecting other devices on to network The communication loads between FCN/FCJ and other devices such as PLC, field devices, PC may influence the control function shown in the following table. Table Influences on FCN/FCJ Communication Protocol Protocol Method Effects on FCN/FCJ Unicast Communications to one Communications to any devices other than FCN/FCJ never specific node adversely affect FCN/FCJ. Multicast Communications to one specific group of nodes Broadcast Communications to all As communication processing has high priority, all types of nodes in the network communication frames, including irrelevant ones, are received by the FCN/FCJ. When broadcast communication loads are too high, the control processing of the FCN/FCJ is influenced (for example, processing delay can occur).

The broadcast communications increase the communication loads, so that connecting FCN/FCJ to the network with broadcast communications should be avoided. If the connections are required, separate broadcast domain via router or VLAN shown in the following documentation.

SEE ALSO For the use of routers, refer to the following: 1. “Figure Example of a Single Network Configuration” and “Figure Example of a Separated Network Configuration” in “2.2 Network Basic Definitions (IP Address Settings)” 2. “3.6 Connecting Routers to Control Networks”

CAUTION

1. The broadcast communications are also used as ARP (Address Resolution Protocol). If a number of devices using ARP are connected to the network, the massive broadcast communications may occur. 2. Even if under not frequent broadcast communication environment, the massive broadcast communication might occur due to the abnormal condition of devices. Therefore the switching HUBs with the broadband suppression function are recommended to be installed.

<3. Examples of Network Configurations> 90

Configuration of Routing Information You need to perform default gateway settings to the devices connected to control networks that communicate to upper networks.

SEE ALSO For the configuration of default gateway, see "2.2 Network Basic Definitions (IP Address Settings)".

You need to add routing information besides default gateway settings when connecting two or more routers to a control network and configuring routers to switch according to the target device. In this case, don't change the routing information dynamically from external equipment and specify routing information statically as in the example of this chapter. How to Configure FCN/FCJ 1. Click the link of [Edit] in "System File Setting" from the maintenance menu. Select "IP Routing File" on the system configuration file window and click [OK].

2. On the IP routing file edit window, add the routing information in the following format. net :Subnet mask gateway host gateway "net" is the keyword that indicates the is a network; "host" is the keyword that indicates the is a host. Specify names or IP addresses for and . If a subnet mask is omitted, the subnet mask for the destination IP address class is used. e.g. net 172.20.3.0 :ffff0000 gateway vds01 net 192.168.9.0 gateway 192.168.0.252 host hmi10 gateway 192.168.0.252 How to Configure VDS Add routing information using the ROUTE command on the DOS command window. e.g. ROUTE -P ADD 192.168.99.0 MASK 255.255.255.0.192.168.6.10

3.7 Connecting Several Control Networks to VDS When connecting devices other than FCN/FCJ (e.g. PLC), you may well connect to another network, separating physically from the network connecting to FCN/FCJ. Thereby communications with devices other than FCN/FCJ using exclusive protocols (e.g. MELSEC-NET, FL-NET) can be guarded from external perturbations arise from the communications to FCN/FCJ.

3.11 Duplexing Communications between FCN/FCJ and FCN/FCJ in Different Segments The following explains a typical configuration example of duplexing communications between FCN/FCJ and FCN/FCJ located in different segments via routers.

Important

To duplex communications between FCN/FCJ and FCN/FCJ located in different segments, an application program is required to switch communication paths. For the communication switching application program, place two CONNECT function blocks that specify IP addresses for network A and B, for each connection destination. It requires two channels with one connected device. The maximum number of channels for FCN/FCJ communication prepared for each FCN/FCJ is 15. When using communication switching application program, pay attention to the number of channels.

Figure Example of Remote Operation

• As a WAN, you can use ISDN, leased line, frame relay or inexpensive internet. If you perform operation and monitoring remotely, choose an optimum WAN after due consideration of traffic at operation and monitoring, available network infrastructure, etc. To realize a full-scale operation, it is recommended to employ high-speed infrastructure, assured bandwidth, depending on the scale of operation. • For connection part of a WAN, routers supporting protocols for connecting telephone lines, ISDN, leased lines, etc. are needed. If necessary, consider the installation of a firewall, VPN (Virtual Private Network) to acquire the needed security and band. Firewalls protect against external unauthorized accesses and tampering. VPN protects against wiretapping activities and passing off. For the network securities, follow the network policy of your company. • For communication band of the part of WAN, calculate the actual traffic and employ the infrastructure with excess capacities. Consider the traffic when starting HMIs or time when events are concentrated as well as steady communication load when collecting data.

SEE ALSO For the estimation of traffic, see "2.3 Communication Performances".

• For infrastructures of WAN, use services provided by manufacturers of communication infrastructure of each area (e.g. in Japan, NTT). WAN may be suspended due to accidents or engineering works. You can set backup WAN or duplex routers as necessary. See manuals of the router in use for the detailed procedures.

3.16 Connecting FCN/FCJ and VDS via WAN You may want to install VDS and FCN/FCJ in remote places connected via a WAN (leased line, telephone line, ISDN, etc.). It is difficult to completely ensure communications between VDS and FCN/FCJ via WAN, because 100 Mbps Ethernet is assumed to be used for communications between them; in addition, a general WAN cannot guarantee band or response time and operation test with a WAN is not performed at developing process. Example of Construction The following figure indicates an example of construction. Note that this example only illustrates reference information, of which operations are not guaranteed.

Notes for Communication Performances In the example above, VDS data server acquires data of remote FCN/FCJ. Between a WAN and the connecting part, routers according to the infrastructure are installed. The communications between VDS data server and FCN/FCJ include steady data acquisitions as well as uploading of definition data at starting-up, and concentrations of events. Therefore, you should employ the infrastructure with excess band for the WAN to correspond to the traffic during starting-up and event concentration, in addition to the steady state.

SEE ALSO For the estimation of communication performances, see "2.3 Communication Performances".

Configurations Be sure to configure the default gateway of remote FCN/FCJ and VDS correctly.

<3. Examples of Network Configurations> 116

Duplexing WAN Part The part of router and WAN can be duplexed using a duplexed network function of the router. As shown in doted lines in the figure above, connect backup routers to HUBs-A and to the WAN for the backup side. The WAN on the primary side and on the backup side should be physically different. With that configuration, if the WAN (or the router supporting WAN) fails, the path is switched automatically over another one. For a duplexed network function of a router, see the manual of each router.

TIP Because the communication band on a WAN is not completely guaranteed, the STARDOM duplexed control network function does not apply to the part of the WAN network.

Configurations Be sure to configure the default gateway of the remote FCN/FCJ and VDS correctly.

3.18 Synchronizing Times among Nodes To synchronize times of event occurrences, you need to synchronize times among nodes of the control network. On STARDOM, the time between nodes can be synchronized using SNTP (Simple Network Time Protocol; refer to RFC2030), a general technology for the time synchronization function of Ethernet. The accuracy of the synchronization is assumed to be 1 second or shorter, which is because VDS uses a PC and Windows for the platform, and Ethernet and TCP/IP for the communication protocol. Example of Construction The following figure indicates an example of construction when synchronizing times on control network.

<3. Examples of Network Configurations> 118

How to Configure the Time Synchronization Function SNTP has server and client functions. Server functions allow transmission of their own times. Client functions allow reception of the time for synchronization of their own times. It is also possible to run server and client functions simultaneously in order to send (relay) the time received from another SNTP server to other machines. SNTP configuration methods in different system configurations are described below:

[If a STARDOM system is connected to the intranet of a company] As shown in the above configuration example, simultaneously run SNTP server functions and SNTP client functions in the VDSs to receive the time from the SNTP server in the company for delivery to the FCNs/FCJs.

TIP In the domain environments of Windows operating systems, time in client PCs is automatically synchronized. Therefore, if PCs operating VDSs have been used in such domains, the SNTP client functions of these VDSs have already been running. In such cases, run SNTP server functions of the VDSs and send the time to the FCNs/FCJs.

[If a STARDOM system is independent of the intranet of a company] One of FCN-500, FCN-100 or FCJ will be used as an SNTP server. Other FCNs/FCJs or VDSs receive the time from this time master machine. If FCN-500 is used as SNTP server, enable SNTP server in maintenance page. If FCN- 100 or FCJ is used as SNTP server, install the time synchronization server portfolio license to them.

TIP Windows 10/Windows 7 allows the operation of SNTP client functions or the simultaneous operation of the SNTP client and server functions, but not the operation of SNTP server functions only. Therefore, a single Windows 10/Windows 7 machine cannot become the time master.

[When multiple FCNs/FCJs are used exclusively] One of FCN-500, FCN-100 or FCJ will be used as an SNTP server. Other FCNs/FCJs receive time from this time master machine. If FCN-500 is used as SNTP server, enable SNTP server in maintenance page. If FCN- 100 or FCJ is used as SNTP server, install the time synchronization server portfolio license to them. Basic Operations of SNTP Time synchronization communications are performed between SNTP client functions implemented on each node and SNTP server connected to a network. There are two approaches for time synchronization communications: multicasting time to network from SNTP server functions, and inquiring time to SNTP server from SNTP client, that is a client-server (unicast) mode.

TI 34P02K25-01E May 31, 2017-00

<3. Examples of Network Configurations> 119

Adjusting Time on FCN/FCJ FCNs/FCJs have SNTP client functions installed as standard features. Moreover, FCN/FCJ has a function to adjust OS time gradually (smooth adjustment) for synchronizing with times received by SNTP clients, preventing skips or reverses of time. By default, it performs time synchronization of unicast communication every 100 seconds; it performs smooth adjustment for the difference of 5 sec or less; and it does not perform any adjustments for the difference of 500 ms or less. These parameters can be configured in the maintenance homepage on a Web browser. In addition, installation of a time synchronization server portfolio on an FCN/FCJ makes it possible to run SNTP server functions. Adjusting Time of VDS VDSs use the time synchronization function of Windows operating systems. To enable SNTP client/server functions, as following.

• To enable SNTP client functions, use the following methods: 1. Click the [Control Panel] - “Clock, Language, and Region” - “Date and Time” from the start menu. "Date and Time” is displayed. 2. Click the [Change settings] button of “Internet Time” tab. "Internet Time Settings” is displayed. 3. Select the [Synchronize with an Internet time server] check box and specify a server. 4. Click the [Update now] button. 5. Check the message “The clock was successfully synchronized with time, on .” 6. Click the [OK] button to finish the setup.

TIP A PC is synchronous once per a week by initialization of Windows. If time slips large in a day, specify the synchronous every day. (1) Click the [Control Panel]-[Administrative Tools]-[Task Scheduler] from the start menu. (2) Open the [Task Scheduler Library]-[Microsoft]-[Windows]-[Time Synchronization], and right-click the [properties]. (3) Click the [Triggers] tab. (4) Click the [Edit] button. (5) Select the [On a schedule] on “Begin the task”, and click the [Daily] on “settings”. (6) Click the [OK] button, and close all the windows.

• To enable SNTP server functions, check "Time Delivery" on the "Time Synchronization” tab in the FCN/FCJ connection setting tool. Notice that if this function is used on Windows, SNTP client functions need to be already enabled. After the above settings have been entered, restart the PC.

TI 34P02K25-01E May 31, 2017-00

<3. Examples of Network Configurations> 120

Connecting to External SNTP Server As necessary, configure settings to perform the time synchronization with your standard SNTP server or an external standard SNTP server. In the example above, the time is synchronized between SNTP server in a company and VDS.

TIP SNTP servers are managed in a tree structure on the Internet. They can be generally accessed. However, in view of loads on public SNTP servers, it is not practical that all computers acquire time from public SNTP servers. Therefore, it is recommended that an SNTP server in your company be used for VDSs. If you wish to use an external SNTP server, refer for example, to the information that is available at http://www.ntp.org/. In some connecting methods to the Internet, SNTP packets may be blocked by firewalls or other systems.

3.19 Using Hand-held Devices in a Field You can monitor operations, perform adjustment and maintenance of a device at a site by connecting hand-held devices to control networks via a wireless LAN. Example of Construction The following figure indicates a system with a wireless LAN.

Hand-held Hand-held HMI HMI

Figure Example of Network Connecting Hand-held Devices and Wireless LAN Wireless LAN As a typical wireless communication, you can use the wireless LAN standardized by IEEE802.11. In the example above, the radio wave called spread spectrum (SS) is used as the infrastructure mode. The SS mode provides high confidentiality and is resistant against noise. Prepare additional access points or exclusive communication cards. How to Set Wireless Devices Install access points for the IEEE802.11 wireless LAN for each site as in the example. Connect the access points to hubs (with dual network, to HUBs-A). Install IEEE802.11 wireless LAN adapters on hand-held devices. If the access points and hand-held devices are physically remote, or radio waves are not well received due to obstructions, install several access points to use roaming functions. IEEE802.11b communications are performed with radio waves of 2.4 GHz; be careful if the devices using the same band exist in the same area. Securities Comparing to a cable LAN, a wireless LAN is more vulnerable to tapping and unauthorized accesses; you need to install security functions including encipher or user authorization systems. You can use build-in security functions of hand-held devices. Band Note that the speed of a wireless communication is slower than the one with cables. As the maximum communication speed, 11 Mbps (a logical value) can be obtained with 802.11b devices; 54 Mbps (a logical value) can be obtained with 802.11a or 802.11g devices. Estimate communication loads using examples in "Communication Performances" of chapter 2 and choose a wireless LAN device leaving some extra capacities.

Reliability Duplexing can be attained by installing several access points. For the detailed procedures of installation, see the instruction manual of each wireless device.

TIP Duplexed network function of STARDOM on the part of wireless LAN is not guaranteed in performances and reliabilities.

3.20 Connecting Remote Sites Using Wireless Devices You may want to connect remote sites, e.g., between buildings, factories or bases where cable communication infrastructures are not prepared or communication cables cannot be installed (at sea, in a desert, forest, etc.). In these conditions, it is relatively easy and inexpensive to install networks with wireless technologies. Typically, install antennas at two remote sites to communicate using territorial or communication satellite. According to your communication equipment and infrastructure of your area, choose the optimum communication infrastructure. (This document does not cover the specific communication infrastructures.)

Figure Example of Remote Connection with Wireless Devices

Install wireless devices and antennas at two remote sites. Connect the wireless devices to hubs (to HUBs-A with duplexed network) connected to STARDOM devices. For the types and procedures of installation, see the instruction manuals of each device. Securities A wireless LAN is more vulnerable to tapping and unauthorized accesses; you need to install security functions including encipher or user authorization systems. Most of hand- held devices have built-in security functions. Read the manuals of the device in use carefully to configure the device properly. Communication Band Estimate communication loads to choose a wireless LAN infrastructure leaving some extra capacities.

Reliability Duplex the system by installing several wireless devices or antennas if necessary. For the detailed procedures of installation, see the instruction manual of each wireless device.

TIP Duplexed network function of STARDOM on the part of wireless LAN is not guaranteed in performances and reliabilities. Installing wireless devices for communications between a VDS and a controller is not guaranteed. If you actually employ these configurations, be sure to check operations in advance and construct the system on your own authority.

Figure Example of Connecting FCN/FCJ and VDS Data Server to ASTMAC

When connecting ASTMAC and VDS on the same network, you can view various data on ASTMAC (data, trends, reports, and messages) via VDS data server; and data on VDS (data, trends, reports, and messages) via ASTMAC. Notices When Setting IP Addresses STARDOM devices have rules to decide IP addresses. Therefore, when connecting the VDS or FCN/FCJ to the existing ASTMAC system, you should check if the scope of IP addresses on the VDS or FCN/FCJ is not used on the ASTMAC system. If they are duplicated, you should change the settings of the IP addresses.

SEE ALSO For the rules of IP addresses on STARDOM, see "2.2 Network Basic Definitions (IP Address Settings)" and "2.6 Duplexing Control Network".
