Description

The IC695CMM002 is a high-density Serial Communications Module engineered for the GE Fanuc PACSystems RX3i platform. This module provides two independent, software-configurable serial ports through RJ-45 connectors, supporting RS-232, RS-422, and RS-485 interfaces. It serves as a critical gateway for integrating legacy field devices and third-party instrumentation into modern control architectures. Optimized for high-availability environments such as power generation, oil and gas, and wastewater treatment, the module minimizes system downtime by providing stable, high-speed data throughput. Its ability to support up to six modules per rack allows for extensive expansion in complex industrial communication networks.

Features

• Two independent, software-configurable serial ports.
• Supports RS-232, RS-422, and RS-485 physical interfaces.
• Protocol support includes MODBUS Master/Slave, DNP3 Master/Slave, CCM Slave, and generic Serial I/O.
• Adjustable data framing parameters: parity (Even, Odd, None), data bits (7 or 8), and stop bits (1 or 2).
• Selectable baud rates up to 115.2K bps.
• Integrated LED diagnostics for Module OK, Port Fault, and Port Status.

Applications

The IC695CMM002 is widely utilized in industrial automation systems requiring integration with serial-based field instrumentation. Typical applications include power generation control, oil and gas pipeline monitoring, and wastewater treatment facility management where legacy serial connectivity must be bridged to the PACSystems RX3i backplane.

Installation Guidelines

• Ensure the RX3i rack power is disconnected before inserting or removing the module to prevent electrical damage.
• The module occupies a single slot in the RX3i backplane; ensure it is fully seated and the locking lever is engaged.
• Use shielded twisted-pair cabling for RS-422/485 connections to minimize EMI interference in industrial environments.
• Maintain proper grounding of the serial cable shields at one end to prevent ground loops.
• Ensure adequate ventilation around the rack to maintain operating temperatures within the 0 to 60 deg C range.
• Handle the module using ESD-safe practices to protect internal circuitry.

FAQ

Does this module require external converters for RS-485?

No, the IC695CMM002 supports RS-232, RS-422, and RS-485 natively through its software-configurable ports, eliminating the need for external signal converters.

How many modules can be installed in a single RX3i rack?

The system supports up to six IC695CMM002 modules per rack, depending on the specific backplane and power supply configuration.
