GE IC693CMM321 – Series 90-30 Ethernet Interface Communication Module

In stock

Product Introduction:

The IC693CMM321, designed by GE Fanuc (Emerson Automation), is a high-performance single-slot Ethernet communication module for the GE Series 90-30 PLC platform. It functions as a critical communication gateway, enabling the PLC to connect directly to industrial Ethernet networks for real-time data exchange with HMIs, SCADA systems, remote I/O, and other PLCs. It integrates Ethernet and serial communication ports, supporting multi-protocol data transmission to meet diverse industrial networking demands.

Key Features

Multi-Protocol Communication: Supports TCP/IP, Modbus TCP, and SRTP protocols, enabling seamless integration with third-party devices and systems.
Client/Server Capability: Operates as both a client (initiates communication via ladder logic COMMREQ blocks) and a server (responds to requests from HMIs/SCADA).
Dual Serial Ports: RS-232 for module configuration and RS-485 for program loading and serial device communication.
LED Diagnostic Indicators: OK (module status), LAN (Ethernet activity), SER (serial communication) LEDs for real-time fault monitoring.
Non-Volatile Memory: Retains network configuration settings during power cycles, eliminating reconfiguration needs.
Daisy-Chain Support: AAUI ports allow daisy-chaining up to 8 devices without additional network switches.
Robust Industrial Design: Withstands vibration, shock, and wide temperature ranges for deployment in harsh environments.
