Companies can improve productivity of legacy equipment with the new ProSoft IEC 61850 client communication module for ControlLogix systems from Rockwell Automation. The module allows ControlLogix control systems to interface with 61850 intelligent electronic devices (IEDs) to deliver critical equipment control and energy consumption information. This visibility can help management teams immediately improve production efficiency and optimize power use. The module also supports up to 40 IEDs on a parallel redundancy protocol (PRP)-enabled network and up to 225 input/output (I/O) connections. It features a generic object-oriented substation event (GOOSE) publisher to support GOOSE messaging. The GOOSE publisher provides a mechanism to interlock relays or load shed using the IEC 61850 communications network, and it helps eliminate hard wiring to the I/O modules.
