Description
1. Product Title
GE Fanuc IC693CMM321 – TCP/IP Ethernet Coprocessor Communication Module for Series 90-30 PLC
2. Product Overview
The IC693CMM321 is a dedicated Ethernet coprocessor communication module exclusively developed by GE Fanuc for the classic Series 90-30 PLC control system. Installed in standard slots of the CPU main rack or expansion backplane, IC693CMM321 acts as an independent network gateway to break the communication limitation of the PLC’s native serial port, realizing high-speed data interaction between the local PLC, HMI touchscreens, SCADA upper monitoring systems, remote peer PLC controllers and third-party industrial network devices. It adopts client-server dual working mode and supports up to 16 concurrent server connections, executing data read/write and cross-controller linkage via the COMMREQ ladder logic function block. Built-in multi-group status LED indicators and a dedicated reset/test button simplify on-site network fault diagnosis, while industrial-grade electrical isolation effectively suppresses electromagnetic interference and avoids communication packet loss or network disconnection caused by harsh field wiring environments.
