GE Fanuc IC695CMM004 Serial Communications Module

The GE Fanuc IC695CMM004 provides high-density serial connectivity for the PACSystems RX3i control platform. This module features four independent serial ports to manage diverse industrial protocols simultaneously. It acts as a bridge between the central processor and external field devices. Furthermore, the unit supports a mix of RS-232, RS-422, and RS-485 electrical interfaces. Each port utilizes an RJ45 connector for easy cabling and maintenance. This hardware is essential for integrating legacy equipment into modern automated networks. It also expands the communication reach of a single RX3i system significantly.

Protocol Support and Port Functionality

This communications module handles a wide array of industry-standard serial protocols. It supports Modbus Master and Slave modes for broad device compatibility. Furthermore, users can implement DNP3, CCM Slave, and custom Serial I/O configurations. Every port operates individually with its own baud rate and parity settings. Because each channel is isolated, the module prevents ground loops between connected devices. This protection ensures signal integrity in electrically noisy environments. Moreover, the hardware facilitates point-to-point and multi-drop network topologies.

System Capacity and Expansion

The PACSystems RX3i architecture allows for massive serial port expansion via this module. A single CPU rack can host up to six IC695CMM004 units. Consequently, one controller can manage up to 24 unique serial links. This capability makes it ideal for large-scale power metering or drive synchronization. Furthermore, the module integrates seamlessly with Proficy Machine Edition for rapid configuration. The system also supports field firmware updates to add new features or security patches. This flexibility ensures the long-term viability of the communication infrastructure.
