High-Performance Network Interface for Series 90-70 PLCs

The GE IC697CMM741 Ethernet controller module provides a direct network interface for Series 90-70 programmable controllers. This module connects the PLC to an IEEE 802.3 CSMA/CD LAN, enabling high-performance data exchange . System integrators choose this module for its flexible media options and robust communication protocols.

Technical Specifications and Network Interfaces

This Ethernet controller plugs into a single slot in the IC697 PLC rack and features a standard 15-pin AUI port for transceiver attachment . Users can connect to various 10 Mbps media, including 10Base5 (thickwire), 10Base2 (ThinWire), 10BaseT (twisted pair), and 10BaseF (fiber optic) . The module also includes a 9-pin serial port (RS-232) for local connection to a Factory LAN System Manager (GSM) terminal . Battery-backed RAM retains the communication software for a minimum of six months during power outages .

Software and Protocol Support

The GE IC697CMM741 implements communication protocols above the Ethernet data link layer in software, allowing users to choose between TCP/IP or MMS/OSI protocol stacks . This flexibility enables integration with a wide range of automation devices and multi-vendor networks . Users can load or upgrade the software via RAM load, and the module retains the software through its battery-backed memory .

Physical Design and Diagnostics

The front panel features three LED indicators providing clear visual feedback on the module’s status: MODULE OK (power-on diagnostics), ONLINE (network connectivity), and STATUS OK (operational condition) . A restart button on the module forces either a restart of the Ethernet controller or a restart and reload request . The compact dimensions of 2.9 cm x 27.9 cm x 17.8 cm and weight of 0.6 kg allow easy installation in standard PLC racks .

System Integration and Applications

You can integrate this Ethernet controller module into GE Series 90-70 programmable controller systems for direct PLC attachment to Ethernet LANs . The module supports comprehensive station management and diagnostic tools for system monitoring . Applications include factory automation, process control, and other industrial environments requiring high-performance network communication. The transceiver must be IEEE 802.3-compatible with the SQE option enabled .
