IC697PCM711 Series 90-70 Programmable Coprocessor Module | GE Fanuc

Product Overview

The GE Fanuc IC693PCM711, also cataloged as the IC697PCM711 Programmable Coprocessor Module, operates as a dedicated hardware component for localized processing and serial communication execution within Series 90-70 programmable logic controller platforms.

Hardware Specifications

Deterministic Deterministic Networks and Firmware Lifecycle Control

The hardware interface links directly with the VME-derived rack backplane to manage parallel communication sequences without generating software jitter within the main controller memory registers. System performance relies on fixed backplane bus communication velocity mechanisms that match the processor card execution sequence. Hardware configuration profiles enforce strict compliance rules for firmware flash compatibility to avoid functional mismatches during multi-node link startup. Under full industrial operating thresholds, the microcode routines implement balanced I/O density scaling logic to process input frames sequentially without creating hardware-driven instruction overhead.

Frequently Asked Questions

Q: Can the IC697PCM711 coprocessor module be swapped while the rack backplane is energized?

A: No. The backplane design lacks sequential electrical contact pin paths. Hot-swapping the module can induce an electrical short-circuit or cause logical memory corruption across the main processing CPU; power to the entire local rack baseplate must be isolated before module handling.

Q: How is the internal 64K memory array maintained when the system experiences a power loss?

A: The module relies on the centralized lithium battery located on the companion system power supply or the integrated capacitor backup system across the common baseplate rails to sustain volatile RAM data fields during complete supply failures.

Field Installation Guidelines

1. Isolate the main input voltage supplying the Series 90-70 chassis framework before presenting the module for insertion.
2. Slide the circuit card assembly along the plastic tracks of the selected single-slot space, using uniform rearward pressure to lock the dual mechanical extraction levers into place.
3. Terminate serial networks using shielded twisted-pair cables, and anchor the metallic braid to the physical enclosure grounding grid via an explicit, low-impedance termination clip.
4. Separate the communication signal pathways from high-voltage motor controls or power wiring lines by a minimum distance of 30 cm inside the local layout trunking to block magnetic field interference.
