GE Fanuc IC695CMM004LT – 4-Port Serial Communications Module | PACSystems RX3i Platform
Engineering Background: The IC695CMM004LT is a factory-sealed, low-temperature-rated variant of GE Fanuc’s proven IC695CMM004 serial communications module, purpose-built for the PACSystems RX3i backplane architecture. Designed for mission-critical industrial environments where legacy serial protocols (Modbus RTU, SNP, SRTP) must coexist with modern PLC control infrastructure, this module delivers deterministic, multi-port serial connectivity without compromising RX3i rack integrity.
Product Positioning: Targeted at automation engineers integrating third-party serial devices—drives, HMIs, barcode scanners, weighing systems, and legacy PLCs—into GE PACSystems RX3i control networks. The LT suffix designates extended low-temperature operation, making it suitable for outdoor enclosures, cold-storage facilities, and northern-climate installations where standard modules may fail.

Engineering Advantages
- 4 Independent Ports: Each port is individually configurable for RS-232 or RS-485, eliminating the need for multiple single-port modules and reducing rack slot consumption.
- LT Temperature Rating: –40°C lower operating limit covers the most demanding cold-climate and outdoor enclosure deployments where IC695CMM004 (standard) cannot be specified.
- Protocol Flexibility: Native Modbus RTU master/slave support enables direct integration with thousands of third-party field devices without gateway hardware.
- Backplane-Powered: No auxiliary 24 VDC wiring required; simplifies panel design and reduces failure points.
- Proficy ME Integration: Full configuration and diagnostics within GE’s Proficy Machine Edition IDE; no proprietary tools required.
- Port Isolation: Optical isolation between ports prevents ground-loop faults from propagating across the serial network.
System Architecture & Signal Flow
The IC695CMM004LT occupies a single universal slot in any IC695CHS-series backplane. The RX3i CPU communicates with the module via the high-speed backplane bus; the module’s onboard processor handles protocol framing, baud-rate generation, and error detection independently, offloading the CPU. Each of the four RJ-45 ports presents a configurable RS-232 (DTE) or RS-485 (2-wire or 4-wire) interface to field devices. Port configuration is performed entirely within Proficy Machine Edition hardware configuration—no DIP switches or jumpers required. Firmware updates are applied over the backplane without module removal.

Technical FAQ
Q: Is IC695CMM004LT a drop-in replacement for IC695CMM004?
A: Yes. The LT variant is electrically and firmware-identical to the standard IC695CMM004; the only difference is the extended low-temperature operating rating. No hardware configuration changes are required.
Q: Can each port run a different protocol simultaneously?
A: Yes. Each port is independently configured in Proficy Machine Edition and can run a different protocol (e.g., Port 1 as Modbus RTU Master, Port 2 as SNP Slave) simultaneously.
Q: What is the maximum cable length for RS-485?
A: Up to 1,200 m (4,000 ft) at 9,600 bps with proper termination resistors. Cable length decreases at higher baud rates per EIA-485 standard.
Q: Does this module support Modbus TCP?
A: No. IC695CMM004LT is a serial module only. For Modbus TCP, specify the IC695ETM001 Ethernet module.
Q: What warranty is provided?
A: Konmask.com provides a 90-day functional warranty on all modules. Extended warranty options available on request.
