GE Fanuc IC693CPU363-AB Series 90-30 CPU card

Configured for high-speed logic execution and multi-port serial communication in Series 90-30 PLC systems, the GE Fanuc IC693CPU363-AB (IC693CPU363 CPU Module) provides direct physical/electrical execution.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The module utilizes an Intel 80386EX processor running at 25 MHz to drive internal backplane bus communication velocity across local and expansion baseplates. High-density I/O scans are executed with deterministic scan times down to 0.22 ms per 1K of Boolean logic. Onboard firmware flash compatibility enables long-term system maintainability and firmware updates, maintaining synchronization across expansion racks without disturbing non-volatile Flash logic backup storage.

Frequently Asked Questions

Q: What are the backplane current draw requirements for the IC693CPU363-AB?

A: The IC693CPU363-AB draws 890 mA at 5 VDC directly from the baseplate backplane bus. The rack power supply load calculations must account for this current to prevent supply rail voltage dips.

Q: How are serial communication protocols partitioned across the three physical interfaces?

A: The serial port on the power supply supports SNP and SNP-X slave protocols for programming devices. Ports 1 and 2 built into the CPU support RTU slave as well as SNP and SNP-X master/slave configurations for HMI and SCADA integration.

Field Installation Guidelines

1. System De-energization: Ensure primary supply power to the baseplate and connected I/O chassis is completely isolated prior to mounting or removing the CPU unit.
2. Slot Seating: Insert the IC693CPU363-AB into Slot 1 of the CPU baseplate (adjacent to the power supply). Press firmly until top and bottom retention clips snap into the frame.
3. Serial Cable Shielding: Connect RS-232 and RS-485 serial cables using shielded twisted-pair (STP) wiring. Terminate cable shields directly to chassis ground at one end to minimize noise coupling.
4. Serial Port Grounding: Connect the 15-pin D-sub drain wire to the functional earth (FE) terminal on the baseplate chassis to protect communications against severe industrial EMI.
