GE IC693ADC311D Alphanumeric Display Coprocessor Module

The GE Fanuc IC693ADC311D, also cataloged as the IC693ADC311 Alphanumeric Display Coprocessor Module, operates as a dedicated hardware component for display, report, and alarm processing within CIMPLICITY 90-ADS System environments. Powered by an onboard 80C188 microprocessor, the unit offloads serial communication processing and operator interface management directly from the main CPU backplane.

Hardware Specifications

Dedicated Hardware Features

The IC693ADC311D coprocessor interfaces directly through the Series 90-30 backplane bus, utilizing high-speed backplane bus communication protocols to offload text formatting and serial data transmission. The onboard 80C188 processor manages real-time message queuing, status reporting, and hardware alarm triggering independently of the base CPU scan cycle. Firmware flash compatibility ensures seamless system synchronization without demanding additional PLC memory execution cycles during serial burst operations.

Frequently Asked Questions

Q: Does the IC693ADC311D module support hot-swapping during active PLC operation?

A: No, Series 90-30 backplanes do not support insertion or removal of I/O or coprocessor modules while power is applied. Power to the baseplate must be disconnected prior to installing or removing the unit to prevent hardware latch-up or damage to the backplane communication bus.

Q: How are the serial communications ports configured on the IC693ADC311D?

A: The module supports soft configuration through system software (Logicmaster 90 or VersaPro). Port parameters, baud rates, parity, and operating modes are defined in the rack configuration setup and written to the module upon CPU hardware configuration download.

Field Installation Guidelines

1. Power Isolation: Ensure all 120/240 VAC and 24 VDC power sources to the Series 90-30 baseplate are isolated and verified zero-energy before seating the module into the backplane slot.
2. Backplane Engagement: Align the rear edge connector of the module with the target slot on the IC693 baseplate. Press firmly at the top and bottom of the module frame until the plastic retention lever clicks into place.
3. Cable Shielding and Grounding: Connect serial communication cables using shielded twisted-pair conductors. Terminate cable shields directly to the rack earth ground lug to prevent electrical noise coupling on the RS-232/RS-422/RS-485 serial lines.
4. Wiring Strain Relief: Route interface cabling away from high-voltage AC lines or motor drives. Secure cables using DIN-rail mounted wire ties to maintain a minimum bend radius and eliminate mechanical stress on the module connector pins.
