GE Fanuc IC693CMM302P Series 90-30 Enhanced Genius Communications Module
The GE Fanuc IC693CMM302P, also cataloged as the IC693CMM302 Enhanced Genius Communications Module, operates as a dedicated hardware component for peer-to-peer global data transfer within Series 90-30 PLC platforms. Installed in a standard option slot on a CPU, expansion, or remote baseplate, the module transfers up to 128 bytes of transmit and 128 bytes of receive data across token-passing Genius bus networks without burdening the primary CPU sweep cycle.

Backplane Bus Communication Velocity & Firmware Flash Compatibility
The IC693CMM302P exchanges global data packets directly over the backplane bus, preserving backplane bus communication velocity while maintaining deterministic real-time data sync across distributed racks. Dedicated onboard processing offloads network protocol execution from the host processor, while firmware flash compatibility ensures seamless instruction alignment with Series 90-30, Series 90-70, and Series Six PLC controllers across system revisions.
Frequently Asked Questions
Q: How does the IC693CMM302P module handle hot-swapping or baseplate slot restrictions during maintenance?
A: The IC693CMM302P must be installed or removed only when baseplate power is completely switched off. It occupies a single I/O slot and functions in any slot except the dedicated CPU slot on slot-based baseplates.
Q: What is the maximum node capacity supported when deploying the IC693CMM302P in a Series 90-30 system?
A: A single IC693CMM302P module connects up to 31 Genius bus devices. By installing two modules in a single PLC rack, the total supported node capacity scales up to 62 devices.
Field Installation Guidelines
- Ensure system backplane power is entirely disconnected prior to inserting or seating the communication module into the selected rack slot.
- Route Genius bus shielded twisted-pair cabling away from high-voltage AC power lines and variable frequency drive output conduits to minimize noise interference.
- Terminate both physical ends of the Genius bus network using 75 Ohm or 100 Ohm terminating resistors matched to cable impedance.
- Attach the cable shield drain wire directly to a clean panel protective earth ground point to maintain 1500 VDC galvanic isolation performance.
