Description
The GE Fanuc IC693CMM311N, also cataloged as the IC693CMM311 Communications Coprocessor Module, operates as a dedicated hardware component for offloading serial protocol execution and high-speed data transmission from the main CPU within Series 90-30 PLC systems. Installed directly into a modular CPU baseplate slot, the module processes multi-point serial communications across independent RS-232 and RS-485 interfaces via SNP, CCM, and Modbus RTU Slave protocols without increasing CPU scan cycle times.

Backplane Bus Communication Velocity & I/O Density Scaling
Interfacing directly with the Series 90-30 logic backplane, the IC693CMM311N maintains backplane bus communication velocity by executing serial message framing, checksum verification, and protocol handshakes asynchronously. Dual independent serial ports enable simultaneous multi-drop and point-to-point topologies across expanded rack setups. Internal optical isolation barriers protect internal backplane traces from ground loop currents and transient voltage surges on serial field loops.
Frequently Asked Questions
Q: Is the IC693CMM311N compatible with Series 90-30 embedded CPU baseplates?
A: No. The module requires a modular CPU architecture (such as CPU 311, 313, 323, or 331) and does not support embedded CPU units (such as CPU 311E or 313E).
Q: Can both serial ports on the IC693CMM311N operate simultaneously on Modbus RTU?
A: Yes. Both ports can be configured independently for Modbus RTU Slave protocol execution or mixed with SNP and CCM operations.
Q: How is physical signal splitting handled for dual-port wiring on the IC693CMM311N?
A: Signal pinouts from the high-density front interface are split into independent Port 1 (RS-232) and Port 2 (RS-232/RS-485) field connections using the dedicated IC693CBL305 wye cable.
Field Installation Guidelines
- Isolate all main power sources supplying the PLC chassis and connected external communication networks prior to module insertion.
- Hook the upper rear latch of the IC693CMM311N into the top slot notch of a compatible Series 90-30 baseplate.
- Press the lower portion of the module firmly into the rack until the backplane bus connector fully seats and locks into position.
- Attach the IC693CBL305 wye cable to the front panel serial connector and secure the strain-relief thumb screws.
- Ground all communication cable shield conductors at a single earth point to eliminate common-mode ground loop noise across fieldbus drops.
