GE Fanuc PACSystems RX3i IC695CMU310-DM Serial Communications & Redundancy Control Module
The GE Fanuc IC695CMU310-DM is a PACSystems RX3i communication and central processor module engineered for demanding process automation and marine/offshore applications. Operating over high-speed PCI 2.2 bus architecture within the RX3i Universal Backplane, the IC695CMU310-DM delivers deterministic control, integrated serial communication handling, and native support for Max-ON hot-standby redundancy systems.
The unit integrates two isolated serial channels (RS-232 and RS-485) directly on the front fascia, providing point-to-point and multidrop field connectivity for marine alarm monitoring systems (AMS), generator power management systems (PMS), burner management controls, SCADA interfaces, and RTU telemetry networks. Hardware revision suffix -DM provides enhanced backplane bus arbitration, expanded indexed array handling, and firmware-stabilized flash write endurance under harsh electrical transit conditions.

Key Features
- Dual Isolated On-Board Serial Interfaces: Independent RS-232 and RS-485 ports support Modbus RTU Master/Slave, SNP/SNP-X, and C-programmed Serial I/O protocols without consuming auxiliary expansion channels.
- High-Speed Execution Engine: Powered by a 300 MHz 32-bit x86 microprocessor paired with 10 MB battery-backed user execution RAM and 10 MB non-volatile flash storage.
- Dual-Architecture Backplane Interface: Interfaces via high-density 3U PCI 2.2 bus for high-bandwidth process data routing while maintaining legacy GE Fanuc Series 90-30 serial backplane bridge synchronization.
- Max-ON Hot-Standby Support: Hardware-level coordination for bumpless switchover architectures across mission-critical redundant controller pairs.
- Ruggedized Noise Suppression: 1500 V RMS optical and magnetic isolation on serial lines to eliminate ground loop voltage spikes in harsh marine switchboard and propulsion environments.
Applications
- Marine Power Management Systems (PMS): Load-dependent start/stop, blackout prevention, and bus-tie synchronization interfacing via Modbus RTU to marine switchgear protection relays.
- Offshore Vessel Alarm & Monitoring (AMS): Main propulsion telemetry aggregation, bilge/ballast valve sequencing, and exhaust gas scrubber monitoring.
- Turbine & Auxiliary Boiler Control: Fuel-gas loading systems, dual-fuel burner sequencing, and steam header pressure balancing.
- SCADA & Remote Telemetry Units (RTU): Distributed communications gateway linking legacy Series 90-30 racks to plant-wide supervisory networks.
- Water/Wastewater Remote Lifting Stations: Multi-drop telemetry networks handling long-distance differential RS-485 serial communication to peripheral flow and level instrumentation.

Frequently Asked Questions
Can the IC695CMU310-DM replace an IC695CMU310-AA or -AB without rewriting logic?
Yes. The IC695CMU310-DM is backwards-compatible with all earlier hardware and firmware iterations within the CMU310 series. The logic developed in Proficy Machine Edition / PAC Machine Edition automatically downloads and runs without ladder or structured text alterations.
What is the maximum transmission distance for the COM2 RS-485 port?
Using certified marine-grade low-capacitance twisted shielded pair cable (such as Belden 3105A or equivalent 22 AWG), COM2 supports cable runs up to 1,200 meters (4,000 feet) at baud rates up to 19.2 kbps. At high speeds (115.2 kbps), keep runs below 300 meters and maintain line termination.
Why does the module take up two slots when only one backplane connector appears active?
The high-speed PCI bus protocol requires thermal venting and trace clearance for the internal 300 MHz processor and dual serial transceivers. The housing spans two slots to manage heat dissipation in unventilated IP54/NEMA 4X industrial enclosures.
Does COM1 RS-232 provide +5 VDC power on Pin 9?
No. Unlike some legacy Series 90-30 CPU ports, the RX3i IC695 series COM1 RS-232 interface is strictly signal-isolated and does not supply 5 VDC on the 9-pin interface. If you are using external RS-232 to RS-485 converters, power them from an external 24 VDC auxiliary loop or supply logic power from Pin 5 on COM2.
What causes a red blinking “PORT FAULT” LED?
A blinking red status indicates a protocol or physical link mismatch: incorrect baud rate, incorrect parity bit selection, framed checksum/CRC failures, or wiring reversal on the RS-485 A/B differential lines. Double-check that Pin 10 (RD A / Data -) and Pin 11 (RD B / Data +) match the slave equipment nomenclature.
