GE Fanuc IC693PCM311 Series 90-30 Coprocessor Module
The GE Fanuc IC693PCM311, also cataloged as the IC693PCM311 programmable coprocessor module, operates as a dedicated hardware component for offloading real-time mathematical calculations and custom serial communication execution within Series 90-30 platforms. It executes user-defined C and MegaBasic routines independently from the primary CPU backplane scan cycle, providing non-blocking data processing and multi-protocol conversion across two built-in serial ports.

Industrial Controller Architecture & Communication Determinism
Configured for high-speed serial protocol execution, the IC693PCM311 manages complex algorithmic routines without burdening the main PLC CPU. Backplane bus communication velocity supports fast block-data transfers between the coprocessor's internal memory buffers and the central system memory. Flexible RS-232, RS-422, and RS-485 physical layer configurations allow real-time device interfacing, while strict firmware compatibility ensures deterministic task execution across Series 90-30 baseplate slots.
Frequently Asked Questions
Q: How does the IC693PCM311 exchange data with the main Series 90-30 CPU module?
A: The coprocessor uses dual-port RAM across the standard backplane bus, allowing the main PLC CPU to read and write configured memory tables asynchronously without extending ladder logic scan times.
Q: Which serial communication physical layers are supported by the module's dual ports?
A: Port 1 supports RS-232 or RS-485 hardware configurations, while Port 2 supports RS-232, RS-422, or RS-485 modes for interfacing with third-party devices, scales, and barcode readers.
Q: Does the IC693PCM311 require additional backplane power planning during rack design?
A: Yes, because the onboard 32-bit processor draws up to 500 mA (nominal) from the backplane +5 VDC bus, system engineers must account for this load when calculating total rack power supply capacity.
Field Installation Guidelines
Insert the IC693PCM311 into any available option slot of a Series 90-30 baseplate, ensuring the module firmly seats into the backplane connector before tightening the top retaining screw. Connect serial device cabling using shielded twisted-pair conductors, terminating RS-485 bus structures with 120-ohm resistors across the physical end-nodes. Keep serial communication wiring isolated from 120/230 VAC power conduits by a minimum clearance of 300 mm to suppress noise coupling. Verify panel ventilation to keep ambient temperatures within 0 to 60 deg C around the rack enclosure.
