GE IC693CPU341J CPU Processors

The GE Fanuc IC693CPU341J, also cataloged as the IC693CPU341 CPU Module, operates as a dedicated hardware component for central logic processing and I/O execution within Series 90-30 PLC platforms.

Hardware Specifications

Backplane Bus Communication Velocity and Firmware Integration

The IC693CPU341J utilizes an 80188 processor operating at 20 MHz to maintain deterministic backplane bus communication velocity across local and expansion racks. Direct backplane addressing channels discrete and analog I/O memory tables to system registers without causing internal communication bottlenecks. Full firmware flash compatibility allows program logic and execution parameters stored in non-volatile memory to remain intact across system power outages, providing consistent scan cycles across connected chassis.

Frequently Asked Questions

Q: What are the backplane current draw restrictions for the IC693CPU341J during system operation?

A: The IC693CPU341J draws 490 mA directly from the 5 VDC backplane supply rail provided by the baseplate power supply unit. Hot-swapping is prohibited; incoming primary power must be fully isolated before module insertion or removal.

Q: How is programming and serial communication physically interfaced on this CPU model?

A: The IC693CPU341J relies on the 15-pin D-sub serial port hosted directly on the baseplate power supply module, which supports the SNP protocol for connection to programming software, Hand-Held Programmers (HHP), and HMI panels.

Field Installation Guidelines

1. Power Disconnection: Fully isolate all primary AC/DC power sources connected to the baseplate and expansion racks prior to physical installation or extraction.
2. Baseplate Slot Seating: Align the rear module connectors with Slot 1 of the CPU baseplate directly adjacent to the power supply. Press firmly until the top and bottom frame latches lock into position.
3. Serial Communication Shielding: Connect the SNP serial cable using shielded twisted-pair (STP) conductors. Connect the cable shield directly to functional earth (FE) at the power supply connector end to protect signal integrity against severe industrial EMI.
