GE Fanuc IC693CMM321-DE Ethernet Controller Interface Module

The GE Fanuc IC693CMM321-DE Ethernet controller interface module provides 10/100 Mbps Ethernet connectivity for GE Fanuc Series 90-30 PLCs, delivering reliable network access for PLC programming, remote I/O communication, and real-time data exchange with HMIs, SCADA servers, and higher-level systems. It uses a single RJ-45 port with auto-MDI/MDIX and supports auto-negotiation between 10 and 100 Mbps, running standard TCP/IP alongside GE Fanuc Ethernet messaging protocols, and it exposes status via Link/Activity and Speed LEDs so technicians can quickly verify link health. Housed as a backplane plug-in module, the IC693CMM321-DE is powered from the Series 90-30 backplane and is designed for an industrial ambient operating environment, making it suitable for deployment in demanding manufacturing, process, or utility facilities where robust Ethernet connectivity is required. Used to connect PLCs to programming tools, remote I/O networks, HMIs, and supervisory systems, this module supports common replacements in GE Fanuc architectures and is typically found in discrete manufacturing lines, process plants, water treatment, power utilities, and material handling networks that depend on real-time data exchange.
