GE Fanuc IC693CMM311 Series 90-30 Communications Control Module
The GE Fanuc IC693CMM311P, also cataloged as the IC693CMM311 Communications Coprocessor Module, operates as a dedicated hardware component for serial data communication within Series 90-30 PLC platforms. The hardware acts as an intelligent communication interface, offloading serial protocol processing from the central processing unit. Equipped with two isolated female 25-pin D-shell serial ports, the module routes field data from supervisory networks, human-machine interfaces, and remote telemetry units into the internal PLC register structures over the backplane bus.

Profinet / EtherNet/IP Deterministic Networks and I/O Density Scaling
The IC693CMM311 handles serial-to-parallel conversion cycles to interface legacy serial structures with the backplane bus. When bridging data from Modbus RTU loops into high-level architectures, the module executes point-to-point register mapping to ensure data availability on upstream Profinet or EtherNet/IP deterministic networks. This integration prevents communication bottlenecks during high I/O density scaling phases across decentralized systems. System parameterization and data block allocations are maintained inside the register tables via initial configuration software files, maintaining complete firmware flash compatibility with modular CPU assemblies.
Frequently Asked Questions
Q: Can the IC693CMM311 be positioned in a remote or expansion baseplate chassis?
A: No. The IC693CMM311 must be installed exclusively on the primary Series 90-30 CPU baseplate. The expansion baseplate interfaces lack the direct parallel processor bus channels needed to execute the high-speed data block transfers required by the coprocessor architecture.
Q: Is it possible to execute hot-swap maneuvers with this communication module?
A: No. The Series 90-30 platform does not feature hot-swap hardware support. Removing or inserting the module while the backplane is supplied with +5 VDC can cause bus faults, drop communication links abruptly, or damage the internal logic gate arrays due to power transients.
Field Installation Guidelines
- Chassis Slot Selection: Turn off all power to the target rack. The IC693CMM311 can occupy any slot on the CPU baseplate with the exception of the dedicated slot 0 reserved for the power supply and the slot dedicated to the CPU. Secure the top and bottom hooks to the chassis frame before fully engaging the backplane plug.
- Port 2 Configuration and Wiring: When utilizing Port 2 for multi-drop RS-485 or RS-422 networks, external hardware configurations require the IC693CBL305 Wye cable adapter or a custom-pinned 25-pin D-shell connector to split out differential wire signals.
- Shield Grounding Protocol: Terminate the outer braided shield of the serial cables directly to the metal housing shell of the 25-pin connector. This links the field line shield to the frame earth ground, diverting high-frequency electro-magnetic transients away from the optical isolation barrier.
- Line Termination: For long-distance RS-485 multi-drop topologies operating at 19.2 kbps, place a 120 Ohm termination resistor across the differential receive lines at the final node of the network segment to counter line signal reflection.
