GE Fanuc IC695CMM004 Serial Communications Modules PACSystems RX3i

Product Overview

Configured for multi-channel serial data routing in PACSystems RX3i platforms, the GE Fanuc IC695CMM004 (IC695CMM004 Serial Communications Module) provides direct physical/electrical execution. The module provides point-to-point and multipoint communication interfaces, converting physical serial layer currents and potentials into standardized data matrices managed directly by the primary system central processing unit via the universal backplane.

Hardware Specifications

Industrial Control & Deterministic Backplane Communication

The processing infrastructure relies on fixed bus tracing rules to execute data exchange alongside main rack assets. The interface adapts cleanly to various configurations, maintaining predictable transmission variables when balancing systemic I/O density scaling profiles across expansion chassis layers. Port configurations and internal data translation loops operate via the central engineering workstation to sustain structural firmware flash compatibility during low-latency messaging updates across standard networks like Profinet or EtherNet/IP deterministic networks.

Frequently Asked Questions

Q: How does the IC695CMM004 module acquire its necessary operational logic voltages?

A: The hardware operates entirely on internal supply routing, drawing 550 mA from the +3.3 VDC universal backplane rail. It does not utilize the +5 VDC bus line or require any external DC input terminal supply connections.

Q: Can all four serial ports be utilized to transmit different industrial automation protocols concurrently?

A: Yes, each port is configured independently through the software workstation. Ports can run distinct baud rates, flow control parameters, parity schemes, and operational modes (such as Modbus RTU Master and custom ASCII string parsing) simultaneously.

Field Installation Guidelines

• Chassis Engagement: Turn off all primary rack power supplies prior to slot alignment. Guide the module into any available open slot on an RX3i Universal Backplane (IC695CHSxxx). Press down until the upper and lower latch arms engage fully to verify backplane grounding contact.
• Line Termination Bounds: When wiring Port 3 or Port 4 for long-distance RS-485 network legs, attach external 120 Ohm resistors across the positive and negative differential signaling pairs at the terminal end to block line noise reflections.
• Shield Grounding Methods: Secure all twisted-pair communication cables with braided shield layers. Connect the shield line exclusively to the enclosure ground terminal bar at the module end to minimize ground potential looping errors.
• Communication Wiring Paths: Route serial interface conductors through dedicated, enclosed panel trays away from high-power three-phase motor supply lines and heavy contactor systems to mitigate electromagnetic noise transfer.
