GE Fanuc IC697CMM742 Ethernet Interface Module

The GE Fanuc IC697CMM742 is a Type 2 Ethernet communication module specifically built for GE Series 90‑70 PLC rack systems. It acts as an independent network co‑processor, establishing 10Mbps IEEE 802.3 Ethernet link for PLC controllers, handling multi‑protocol data exchange and offloading network tasks from the main CPU to improve overall system response performance.

This single‑slot VME module comes with three alternative network ports plus dual serial ports for local configuration and firmware upgrade. Equipped with status LED indicators for rapid on‑site diagnosis, it supports pre‑loaded upgradable firmware. Widely deployed as spare communication hardware for legacy GE 90‑70 automation system maintenance, replacement and network retrofitting projects in heavy‑industry sites.

FAQ

1. Q: Can IC697CMM742 work without GE 90‑70 CPU?
   A: It must be inserted into 90‑70 series PLC backplane rack, cannot operate as standalone communication hardware.
2. Q: What are typical module failure phenomena?
   A: PLC cannot connect via Ethernet, EGD data loss, LAN link alarm, unresponsive remote programming access.

3. Q: How to complete commissioning and diagnosis?
   A: Observe module LED status indicators; configure IP address and EGD table via programming software, upgrade firmware through RS‑485 serial port when needed.
