Product Overview

The GE Fanuc IC693CMM321 Ethernet Interface Module adds Ethernet networking capability to Series 90-30 PLC baseplates. It enables PLC data exchange with supervisory systems and plant networks, supporting integration with HMI/SCADA platforms, distributed control architectures, and Ethernet-based diagnostics or maintenance tools.

Installed on the Series 90-30 rack, the module provides network communications and status indication for reliable operation in industrial automation environments. Connection limits and feature availability can depend on the installed CPU firmware revision.

Typical Use Scenarios

The IC693CMM321 is used to network Series 90-30 PLCs to operator stations and higher-level systems for monitoring and control. Common deployments include manufacturing lines, utility panels, process skids, and material handling systems where Ethernet connectivity is required for HMI screens, SCADA polling, data collection, and remote diagnostics.

It is often selected for retrofit projects to add Ethernet connectivity while keeping the installed Series 90-30 I/O and baseplate architecture unchanged.
