GE Fanuc IC697CMM742 TCP/IP Ethernet Interface Module

The GE Fanuc IC697CMM742 is a sophisticated Ethernet interface module designed for the Series 90-70 PLC rack. This module serves as a bridge between the industrial controller and local area networks, allowing high-speed data transfer across a plant floor. It supports vital communication protocols including SRTP (Service Request Transport Protocol) and Ethernet Global Data (EGD). These capabilities allow the PLC to interact seamlessly with HMI software, SCADA systems, and other controllers. By implementing this module, users can achieve efficient real-time monitoring and advanced data logging in complex automation environments.

Versatile Interface Options and Protocols

The IC697CMM742 offers diverse physical connection possibilities to accommodate various network infrastructures. It includes ports for 10BaseT (twisted pair), 10Base2 (thin coax), and AUI transceivers. Furthermore, the module features built-in RS-232 and RS-485 serial ports for auxiliary communication tasks. Because it supports both configuration-based and logic-based EGD, the module provides engineers with flexible methods for exchanging global variables. This multi-protocol approach ensures compatibility with legacy hardware while supporting modern networked architectures.

Technical Specifications

Reliable Operation and Diagnostics

System reliability remains a core component of the IC697CMM742 design. The front panel includes a dedicated restart button, which allows technicians to reinitialize the network stack without cycling power to the entire PLC rack. A comprehensive set of LED indicators—Module OK, LAN Online, Serial Active, and Status OK—provides instant visual feedback for troubleshooting. For hardware protection, the unit contains a replaceable fuse for the AUI transceiver port. Additionally, users can scale their network capacity by installing up to four of these interfaces within a single Series 90-70 CPU rack.
