I/O modules

Connect Your PLC to the Network

The IC69CMM321 Ethernet interface module seamlessly integrates Series 90-30 PLCs into your industrial network. This module from GE Fanuc (now part of Emerson) enables direct communication with HMIs, SCADA systems, and remote I/O. Consequently, it facilitates robust data exchange and control across your distributed automation architecture.

Communication Ports and Key Features

This module provides three distinct physical ports for maximum flexibility. The AAUI network port connects the IC69CMM321 directly to a 10BASE-T Ethernet LAN. Additionally, an RS-232 RJ-11 serial port serves as the dedicated Station Manager interface. Furthermore, an RS-485 15-pin D-type port functions as the Software Loader port for configuration tasks.

The IC69CMM321 supports both client and server device operations on the network. It can handle up to sixteen simultaneous server connections for multi-point communication. Four status LEDs (OK, LAN, SER, STAT) provide immediate visual feedback on module and port activity.

Technical Specifications and Compatibility

Designed as a single-slot module, the IC693CMM321 fits standard Series 90-30 racks. For full functionality, you need a Series 90-30 CPU with version 6.50 or higher. Earlier CPU versions from 5.03 to 6.04 support only a single SRTP connection.

Integration and Operational Notes

You will typically need an appropriate AAUI cable or external transceiver for network connectivity. This module efficiently bridges the Series 90-30 platform to modern Ethernet-based supervisory systems. It is a key component for implementing remote diagnostics and program management.
