Product Role & System Fit
The GE IC697CMM742-GH is a communications interface module designed to bring Ethernet networking capability to GE Fanuc Series 90-70 PLC systems, a hardware family widely deployed in industrial automation applications over several decades. While newer PLC platforms integrate Ethernet communication directly into the CPU, older Series 90-70 racks rely on modules such as the IC697CMM742-GH to connect controllers to industrial Ethernet networks.
Installed in any available slot on a Series 90-70 rack, the IC697CMM742-GH interfaces with the rack’s backplane and provides physical Ethernet connectivity through multiple port types — including standard twisted-pair (10BaseT), coaxial (10Base2), or AUI interfaces. This flexibility lets engineers tailor networking to existing cabling infrastructure and avoid costly redesigns.
By incorporating the GE IC697CMM742-GH, Series 90-70 PLC installations can communicate over Ethernet using standard TCP/IP and other IEEE 802.3 protocols — enabling integration with SCADA systems, HMI workstations, plant historians, and remote monitoring tools. This networking capability is particularly useful when modern supervisory systems must interface with legacy control architectures without replacing core CPUs.
