GE IC697CMM742-LL

The module installs in a single slot of any IC697 rack and bridges the PLC CPU to a 10 Mbps Ethernet LAN. Three physical network interfaces—10Base-T RJ-45, 10Base2 BNC, and 15-pin AUI—provide flexible cabling options. An onboard RS-232 Local Station Manager port (RJ-11) and RS-485 software port (15-pin D-SUB) are available for configuration, diagnostics, and firmware updates.
