Ethernet Interface Module for Series 90-70 PLC Systems

The GE IC697CMM742-HK functions as an Ethernet communication interface for the Series 90-70 programmable logic controller platform. This module connects the PLC CPU rack directly to Ethernet local area networks. Its design supports high-speed data exchange with SCADA systems, HMIs, and peer PLCs .

Multi-Protocol Communication and Connectivity

This Ethernet interface module features three physical network ports for flexible media connectivity . It supports TCP/IP, SRTP, and Ethernet Global Data protocols for deterministic data exchange . The module also handles Modbus TCP and EtherNet/IP for multi-brand system integration . Moreover, its AUI port accepts external transceivers for legacy media like 10Base5 or 10BaseF . Consequently, this module bridges both modern and legacy industrial network infrastructures.

Diagnostic and Maintenance Features

The IC697CMM742-HK includes four front-panel LEDs for real-time status monitoring . These indicators display module health, network link, and communication activity. A front-panel pushbutton enables local restart and diagnostic mode selection . Additionally, preloaded firmware simplifies installation and supports easy upgrades. For this reason, maintenance personnel can quickly diagnose and resolve network issues.

Physical Specifications and Environmental Ratings

This single-slot module occupies one standard position in the Series 90-70 rack . It measures 3.8 cm x 29.2 cm x 22.9 cm and weighs approximately 0.5 kg . The module operates from a dual-voltage backplane supply at +5 VDC and +12 VDC . Furthermore, it reliably functions from -20 °C to +70 °C in industrial environments .
