Excellent PLC
Product Overview
The GE Fanuc IC697ADC701 is a single-slot coprocessor module designed to enhance Series 90-70 / IC697 PLC systems by offloading display, alarm, and reporting tasks from the main CPU. It runs the Alphanumeric Display System (ADS) software to provide human-machine interface (HMI) functions such as operator displays, alarms, logs, and screens independently of the control logic. The module communicates with the CPU over the backplane and provides serial ports for connection to operator terminals, PCs, or printers.

Frequently Asked Questions (FAQ)
1. What is the main role of the IC697ADC701 in a PLC system?
It performs display, alarm, logging, and operator interface tasks so that the main CPU can focus on control processing.
2. How many ADC modules can be installed in one PLC?
Up to 63 modules can be used within a single Series 90-70 PLC system.
3. How is the ADC configured?
Configuration is completed via software (PCOP development tools), not with hardware switches.
4. What happens if the battery fails?
User memory may be lost. The diagnostic LEDs or startup messages will indicate low battery status.
5. What is the function of the pushbutton on the module?
A short press restarts the ADS software; a long press (over 5 seconds) resets to factory defaults.
6. What types of terminals can it support?
It supports OIT, Mini OIT, VT100, and IBM PC/compatible terminals via TERMF.
7. Can it communicate directly with a printer?
Yes, the module can log alarms and reports directly to a printer through its serial port.
8. Does it require specific firmware compatibility?
Yes, newer ADS versions may need specific module revisions and compatible CPU firmware.
