Emerson PACSystems RX3i IC695ECM850 Ethernet Communication Module

The PACSystems RX3i IEC 61850 Ethernet Communication Module, catalog number IC695ECM850. or ECM850.

connects a PACSystems RX3i controller to an IEC 61850 network, enabling the controller to act as an IEC 61850 Client

and communicate with Intelligent Electronic Devices (IEDs, IEC 61850 Servers) on the network using the IEC 61850

protocol.

Features of the RX3i ECM850 include:

• Support for the following IEC 61850 client features:

o Multiple connections to IEC 61850 servers by TCP/ IP

o Read and write of data / dataset values

o Control Model: all models

o Reporting by exception: buffered and un-buffered reporting

Note: Refer to the PICS, MICS and PIXIT appendices in GFK-2849 for details.

• Supports 10/100/1000Mbps copper, 100/1000Mbps multi-mode fiber, and 100/1000Mbps single-mode fiber

• Supports star (switched), and linear (daisy-chain) network topologies.

• Supports operation in hot standby redundant system

• Supports secure firmware upgrade using Winloader software utility.

• Built-in Command Line Interface (CLI) using the Micro-B USB port.

• Simple Network Time Protocol (SNTP) client support (Multicast and Broadcast)

Sweep Impact of ECM850

The impact of the ECM850 on RX3i CPU sweep time is a function of the number of ECM850 modules in the RX3i

hardware configuration (four maximum) and the I/O data size configured for each ECM850 module. The table below

shows the measured sweep impact of a single ECM850 module for a range of I/O data sizes. Use the data in this table

to calculate expected impact on RX3i CPU sweep times. The configured IO Data size will be available in the message

zone of the IEC 61850 Configurator after configuration validation.
