General information
1 General information ENCS-3m - is a reliable software and hardware platform for building remote control sys- tems for substation and power plants.
Remote terminal unit (RTU) ENCS-3m is designed to create geographically distributed systems:
— at the field level installed devices (ENIP-2, ENB series) which support measurement parameters values, monitoring digital signals and control by digital outputs to switch- gears and mechanism;
— all this devices are connected to RTU ENCS-3m via RS-485/232 lines or local net- works.
RTU ENCS-3m collect, consolidate and distribute necessary data to a top level of con- trol systems. To control data traffic from field level devices ENCS-3m uses absolute and relative apertures. Timestamps of data are assigned by field devices.
ENCS-3m build on 32bit ARM microcontroller and providing continuous operation for remote control systems. To increase reliability system ENCS-3m support warm standby.
ENCS-3m use hard real-time algorithm, and thus provides high performance and relia- bility.
ENCS-3m polls devices according IEC 60870-5-101, Modbus and etc. ENCS-3m support up to 10 ports for device polling.
ENCS-3m allows setup up to 16 channels to transmit data to upper level using 2 LAN and RS-232/RS485 ports. 2 RTUs ENCS-3m are connected through CAN-bus to support warm standby in pair.
RS-485 interface, RS-232, Ethernet can be distributed by the user between data collec- tion from field devices and transmission of information to the top level.
To communicate with the field devices are preferred protocol IEC 60870-5-101, which provides for the regulation of traffic between the RTU and devices, and allows to send a data with timestamp directly from the sources of their formation.

Features
3 Features
3.1 Device poll and sync time ENCS-3m provides polling of the field level devices and produces filtering false frames received from devices. The resulting filtered data is stored in RAM and are available for the rest of the program RTU modules.
Starting polling performed on all ports in a one time. Thus, all the data obtained from the field level devices have the same meanings recorded for a time
If the device has an internal clock, ENCS-3m provides time synchronization within the IEC 60870-101 protocol, as well as through the proprietary protocol for some meters.
3.2 Telecontrol ENCS-3m can transmit command according to IEC 60870-5-101 (Single command (<45>), Double command (<46>)) and Modbus (Force single coil (05).
For Modbus you can choose type of retranslation Single command (<45>) from top level to Modbus command (05) for field level device.
3.3 Spontaneous transmission Spontaneous transmission mode involves the transfer option under certain conditions: change the value of the parameter is outside the redistributions predetermined value (setpoint or aperture). The value of tolerance can be set both in absolute and relative terms (as a percentage of the current value). Also two setpoints can be specified, at the intersection where the parameter is queued for transmission. This algorithm mode is used to control the voltage when it is necessary to pass a parameter at the exit of some of its frame.
3.4 Cyclic transmission The RTU may transmit parameters to the top level at predetermined intervals (default 2 min.).
3.5 Background scan Background scan has lowest priority for transmitting and start only when data buffer according to IEC 60870-5-101–2006 (IEC 60870-5-104–2004) is empty.

For writing new firmware to ENCS-3m use special update utility “ES Boot- loader”. In addition, you can download it from our web site.
For the search the RTU in local network, use software «ES Find IP».
5.7 Data transmission
RTU ENCS-3m provides continuous polling of devices connected to the ports and data transfer to the top level through the channels. RS-232, RS-485 can be port or chan- nel. Ethernet can be used as both the ports and the channels. GPRS can be only chan- nel.
All data can be transmitted on 16 channels simultaneously. In RS-232, RS-485 can be arranged up to 10 channels, via Ethernet interfaces and GPRS - up to 16 channels. Each of the 16 channels individually configurable.
For the channel is also available RS-TCP function, the so-called a «through channel», through which one can connect directly to one of the polled devices.
Server mode
If ENCS-3m channel configured as a server, ENCS-3m awaits client connection. You need to configure the client's IP-address and TCP-port. Once connected, the client starts the exchange of the selected protocol for this channel. In case of breaking TCP-session ENCS-3m expects of recovery session.
If the client IP-address specified as 255.255.255.255, the available connection from any IP-address.
Client mode
If ENCS-3m channel is configured as a client, then ENCS-3m on the socket initiates a connection with the specified settings in the IP-address of the remote server. After opening the remote connection server (open TCP-session) ENCS-3m ready to exchange the chosen protocol for this channel. In case of breaking TCP-session ENCS-3m provides session restoration.
In client mode, you must specify the server's IP-address and port, which should connect. If you want to use routing in a different subnet, the ENCS-3m can be installed up to 16 routing rules for TCP-packets, which include the interface name, IP network address, network mask, and gateway address.

This companion standard presents sets of parameters and alternatives from which sub- sets have to be selected to implement particular telecontrol systems. Certain parameter values, such as the number of octets in the COMMON ADDRESS of ASDUs represent mu- tually exclusive alternatives. This means that only one value of the defined parameters is admitted per system. Other parameters, such as the listed set of different process in- formation in command and in monitor direction allow the specification of the complete set or subsets, as appropriate for given applications. This Clause summarizes the pa- rameters of the previous Clauses to facilitate a suitable selection for a specific applica- tion. If a system is composed of equipment stemming from different manufacturers, it is necessary that all partners agree on the selected parameters.
