GE IC693CPU350-CF PLC systems

Configured for central logic execution and I/O scanning in Series 90-30 PLC systems, the GE Fanuc IC693CPU350-CF (IC693CPU350 CPU Module) provides direct physical/electrical execution.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Compatibility

The module uses an Intel 80386EX microprocessor operating at 25 MHz to drive internal backplane bus communication velocity across local and expansion baseplates. High-density discrete and analog I/O tables are scanned with deterministic timing down to 0.22 ms per 1K of Boolean logic. Onboard firmware flash compatibility enables long-term maintainability, supporting program execution from non-volatile Flash memory without introducing backplane latency across connected system racks.

Frequently Asked Questions

Q: What are the backplane current draw requirements for the IC693CPU350-CF?

A: The IC693CPU350-CF draws 670 mA at 5 VDC directly from the baseplate power supply bus. Hot-swapping is prohibited; primary supply power must be isolated prior to insertion or removal of the module.

Q: How is serial programming communication handled on the IC693CPU350-CF?

A: The CPU module lacks a dedicated onboard serial connector and relies on the RS-485 serial interface located on the baseplate power supply, which natively supports SNP and SNP-X slave protocols for programming hardware and HMI connection.

Field Installation Guidelines

1. Power De-energization: Isolate all incoming AC/DC power sources to the main baseplate and linked expansion chassis prior to mounting or removing the CPU unit.
2. Baseplate Slot Alignment: Insert the IC693CPU350-CF into Slot 1 of the CPU baseplate directly adjacent to the power supply unit. Seat the module firmly into the backplane connector until retention clips lock.
3. Serial Cable Grounding: Connect the RS-485 serial communication cable shield directly to functional earth (FE) at the power supply connector to maintain noise immunity in high-EMI environments.
