IC693ADC311 Alphanumeric Display Coprocessor (ADC)
The Alphanumeric Display Coprocessor module (IC693ADC311) is a coprocessor to the Series
90-30 PLC CPU and is used in a CIMPLICITY 90-ADS system. It performs CIMPLICITY
90-ADS display, report, and alarm functions when interfaced to an Operator Interface Terminal
(OIT). The OIT can be a variety of GE devices, a VT100 compatible terminal, or IBM
compatible personal computer running TERMF. Communications with the Series 90-30 CPU is
done over the PLC system backplane.
