Chapter 1:
Introduction
This chapter introduces the PACSystems RX3i IEC 61850 Ethernet Communication Module,
or ECM850 for short. The final pages of this chapter are a glossary that define many of the
terms and acronyms used in the manual.
Chapter 2, Installation explains how to install an ECM850, how to complete port
connections, and how to update the module firmware. It also explains how to install the
ECM850’s Universal Serial Bus (USB) port
driver and describes how the module synchronizes
its internal clock with the RX3i CPU.
Chapter 3, Configuration explains how to complete and download the configuration for
ECM850s, (IEC 61850 Clients), add Intelligent Electronic Devices (IEDs). and select protocol
variables for monitoring and control. This chapter describes how to use PLC Protocol
Variables (PPVs) in RX3i controller applications. It also describes different configuration
mechanisms: online and offline configuration, configuring specific protocol features like
report control block, polling etc.
Chapter 4, IEC 61850 Client System Operation describes I/O scan operation and application
program blocks for use with the ECM850. This chapter also provides an overview of IEC
61850 communications between the ECM850 and IEDs (IEC 61850 servers). This chapter
defines system constraints with regard to PPV usage, memory usage, and other criteria for
using the ECM850 in control applications.
Chapter 5, Diagnostics explains the power-up and reset process, LED blink patterns, status
reporting, and fatal error reporting. It also describes faults and corrective actions.
The Appendices provide reference information about the ECM850 not required for typical
applications.
Appendix A, ECM850 Command Line Interface Support describes an interface to the
ECM850 used primarily for diagnostics and troubleshooting.
Appendix B, IEC 61850 I/O Performance Examples presents several IEC 61850 network I/O
configurations with the measured I/O performance for each as an aid to computing
estimated I/O performance in other scenarios.
Appendix C, Protocol Implementation Conformance Statements (PICS),
Appendix D, Model Implementation Conformance Statement (MICS), and
Appendix E, Protocol Implementation eXtra Information for Testing (PIXIT) collectively
provide details of the ECM850’s abstrac
t communication service interface (ACSI) and other
information required to demonstrate conformance to the IEC 61850 standard.
