Introduction to Real-Time Ethernet II By Paula Doyle, a doctoral researcher with the Circuits and Systems Research Centre at the University of Limerick in Ireland INTRODUCTION IEEE 1588 defines two separate types of clocks: In “Real-Time Ethernet I”, we introduced the basic ordinary and boundary. Boundary clocks (BC) are concepts of Ethernet’s capacity to deliver a real-time employed in devices such as hubs or switches—where (RT) communication system. “Real-Time Ethernet II” more than one PTP communication path (port) exists. introduces some of the RT solutions available to Ordinary clocks exist in devices having a single port— e.g., normal network devices. Each BC port can act as industry today*: PROFInet, EtherCAT and ETHERNET Powerlink. It also provides an introduction to a single a master or ordinary clock in its own segment. standard, IEEE 1588 that is growing in popularity PTP is for networks that support multicasting but amongst RT Ethernet developers to provide sub- keep multicasts within a subnet and where each local microsecond synchronization accuracy of distributed clock fulfills exacting requirements.

Ethercat the New Standard for Measurement Applications Central Backbone for Distributed Systems
C5.2 EtherCAT The new standard for measurement applications Central backbone for distributed systems Dr. Kessel, Jens-Achim ADDITIVE Soft- und Hardware für Technik und Wissenschaft GmbH Max-Planck-Str. 22b, 61381 Friedrichsdorf Abstract In the past years EtherCAT has become a world wide accepted new standard in automation and control. In November 2003 the EtherCAT Technology Group (ETG) was founded and it has grown up to about 900 members from 45 countries in January, 2009. EtherCAT was designed and developed as an open high performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet technology to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs. Once the new standard was introduced for automation and control, it became interesting, too, to use Eth- erCAT also for distributed systems in measurement applications. This paper takes a focus on the special properties of EtherCAT with respect to the usability in measure- ment applications. It shows the capabilities of EtherCAT as a powerful backbone, replacing classical net- works based on CAN or ProfiBUS. In particular aspects of synchronisation and real-time-processing in combination with the compact data packaging are interesting for measurement applications with a big number of distributed analog channels. E.g. in applications where torque and speed of rotating parts are picked up just to measure, to detect or even to prevent oscillations, it is very important to synchronize the sampling of data at the distributed converter modules. Only this allows then to calculate exact phase in- formation from the measured signals and evaluate and prepare the data according to the requirements of an application on top. -

Based on published material it shows the technical principles of the various approaches and tries to put these into perspective. The content given represents my best knowledge of the systems introduced. Since the company I work for is member of all relevant fieldbus organizations and supports all important open fieldbus and Ethernet standards, you can assume a certain level of background information, too. The slides were shown on ETG Industrial Ethernet Seminar Series in Europe, Asia and North America as well as on several other occasions, altogether attended by several thousand people. Among those were project engineers and developers that have implemented and/or applied Industrial Ethernet technologies as well as key representatives of some of the supporting vendor organizations. All of them have been encouraged and invited to provide feedback in case they disagree with statements given or have better, newer or more precise information about the systems introduced. All the feedback received so far was included in the slides. You are invited to do the same: provide feedback and – if necessary – correction. Please help to serve the purpose of this slide set: a fair and technology driven comparison of Industrial Ethernet Technologies.

16 1.6 . LAN Topology Most Computers in Organizations Connect to the Internet Using a LAN. These Networks Normally Consist of A
1.6 . LAN Topology Most computers in organizations connect to the Internet using a LAN. These networks normally consist of a backbone which is a common link to all the networks within the organization. This backbone allows users on different network segments to communicate and also allows data into and out of the local network. Figure 7 shows a local area network which contains various segments: LAN A, LAN B, LAN C, LAN D, LAN E and LAN F. These are connected to the local network via the BACKBONE 1.Thus if LAN A talks to LAN E then the data must travel out of LAN A, onto BACKBONE 1, then into LAN C and through onto LAN E. Figure 7. Interconnection of local networks Networks are partitioned from other networks with a bridge, a gateway or a router. A bridge links a network of one type to an identical type, such as Ethernet, 16 or Token Ring to Token Ring. A gateway connects two dissimilar types of networks and routers operate in a similar way to gateways and can either connect to two similar or dissimilar networks. The key operation of a gateway, bridge or router is that they only allow data traffic through that is intended for another network, which is outside the connected network. This filters traffic and stops traffic, not intended for the network, from clogging-up the backbone. Most modern bridges, gateways and routers are intelligent and can automatically determine the topology of the network. Spanning-tree bridges have built-in intelligence and can communicate with other bridges. -
