GE Fanuc IC693CMM321-CC Ethernet Controller Module

The GE Fanuc IC693CMM321-CC Ethernet controller module provides 10/100 Mbps Ethernet connectivity for GE Fanuc PLC networks, serving as the Ethernet interface in Series 90-30 and RX3i racks. It features an RJ-45 connector with auto-MDI/MDIX, supports standard TCP/IP and GE Fanuc Ethernet messaging protocols, and auto-negotiates between 10 Mbps and 100 Mbps while signaling Link/Activity and Speed for diagnostics. Mounted as a backplane plug-in module and powered by the backplane’s industrial logic supply, it is designed for industrial ambient temperatures and enables reliable controller communication and data exchange between PLCs, HMIs, SCADA servers, and higher-level control systems across discrete manufacturing, process plants, water/wastewater, power utilities, and material handling networks. Common replacements include GE Fanuc IC693CMM321, IC695ETM001, and Allen-Bradley 1756-EN2T, reflecting its role as a standard Ethernet interface in GE Fanuc Series 90-30 and RX3i installations.
