Series 90-30 CPU Module IC693CPU313 GE Fanuc

Product Overview

The GE Fanuc IC693CPU313, also cataloged as the IC693CPU313 CPU Module, operates as a dedicated hardware component for central processing and logic execution within Series 90-30 programmable logic controller platforms.

Hardware Specifications

Industrial Network and Backplane Bus Performance

The module interfaces directly with the proprietary Series 90-30 parallel backplane bus architecture, optimizing internal data transfer velocity and clock synchronization between peripheral discrete and analog I/O modules. Deterministic communications across the control network rely on dedicated timing mechanisms driven by the internal 12 MHz processing architecture. This structural setup limits backplane bus propagation delay, ensuring sequential instruction solution speeds execute consistently regardless of the overall I/O density scaling. The embedded system configuration parameters enforce strict network frame pacing to guarantee uninterrupted memory updates across all linked expansion racks.

Frequently Asked Questions

Q: Does the IC693CPU313 module support hot-swap capabilities within the baseplate?

A: No. The Series 90-30 backplane architecture does not feature power-limiting circuits for hot-swapping. Power to the rack baseplate must be fully isolated before inserting or removing the CPU module to prevent structural damage to the backplane contacts and the internal logic chips.

Q: How is the volatile user program memory preserved during a complete system power disruption?

A: User memory retention relies entirely on the backup battery unit located within the power supply module adjacent to the CPU in the baseplate. If the battery is disconnected or falls below its critical threshold voltage, the internal RAM contents will clear upon power loss.

Field Installation Guidelines

1. Ensure the primary rack power source is switched off prior to mounting the module into the designated slot 1 of the Series 90-30 baseplate.
2. Align the circuit board edge connector carefully with the backplane slot guides and press the module firmly downward until the top and bottom retention hooks click into place.
3. Connect the chassis ground terminal of the baseplate to the local copper grounding bar using a minimum of 4 mm squared (11 AWG) low-impedance conductor.
4. Route all serial communication cables through dedicated, isolated wireways separated from high-voltage AC lines to minimize electromagnetic interference on the logic circuit.
