Product Overview

The Emerson GE Fanuc IC697CMM742 is an Ethernet communication module developed for Series 90-70 PLC systems that require reliable TCP/IP network connectivity. Installed directly into the PLC rack, this module enables high-speed data exchange between the controller and plant-level networks. It supports standard industrial Ethernet communication used for supervisory control, data acquisition, and peer-to-peer controller messaging.

By integrating this module, Series 90-70 PLCs can communicate with HMI stations, SCADA platforms, and other PLCs without additional gateway hardware, simplifying system architecture and improving data transparency.

Hardware Parameters

The IC697CMM742 is designed to support multiple network media types and communication protocols commonly used in legacy and mixed-generation automation systems. Its architecture allows flexible configuration while maintaining deterministic communication behavior.

Key technical characteristics include:

• Support for TCP/IP-based industrial communications

• Compatibility with SRTP and Ethernet Global Data protocols

• Ethernet physical interfaces including 10BaseT twisted pair, 10Base2 thin coax, and AUI transceiver connection

• Integrated RS-232 and RS-485 serial ports for auxiliary device communication

• Typical backplane current consumption of approximately 1.8 A at 5 VDC

• Operating temperature range from 0°C to 55°C

• Front-panel diagnostics with LED indicators and manual restart pushbutton

• Capability to install up to four communication modules in a single Series 90-70 CPU rack

A replaceable fuse on the AUI interface provides additional protection for external transceiver hardware.

Industrial Applications

The IC697CMM742 is commonly used in industrial automation systems requiring Ethernet-based monitoring and control. Typical applications include manufacturing execution systems, process monitoring networks, material handling controls, and distributed PLC architectures.

It supports real-time data sharing between controllers using Ethernet Global Data and reliable request-response communication with supervisory systems using SRTP, making it suitable for both legacy upgrades and ongoing Series 90-70 system maintenance.
