Functions

The Alphanumeric Display Coprocessor Module acts as a coprocessor to the IC697 PLC CPU and is used for alphanumeric display systems, reporting, and alarm functions through various operator interface terminals. It communicates with the IC697 CPU via the system backplane.

Up to 63 Alphanumeric Display Coprocessors can be supported in a single IC697 PLC system, installed in either the main rack or expansion racks. The module can be initialized by pressing a pushbutton on the module or through an attached ADS (PCOP) development system. The status is indicated by three green LEDs on the module.

Installation

    Refer to the Programmable Controller Installation Manual, ADS User’s Manual, and ADS Reference Manual before installation.
    Ensure the power is off before installing the Alphanumeric Display Coprocessor Module.
    Connect the battery to one of the battery connectors on the module.
    Install the module in the rack and turn on the power.
    The top LED will blink during startup diagnostics, and will remain on once diagnostics are complete.

Programming and Configuration

The IC697ADC701 module is programmed and configured via IC647, IC640, or IBM-compatible PCs running PCM Development Software (PCOP), which is connected to the top port of the module. The default serial communication speed is 19,200 bps.

Configuration includes setting the serial port parameters and installing the Alphanumeric Display System software onto the ADC module. MS-DOS® or Windows® programming software can be used for configuration prior to use.

Serial Ports

The module has two RS-232/RS-422/RS-485 compatible serial ports:

    Port 1 (3PL): Typically connected to a host computer's RS-232 serial COM port for communication with PCOP at 19.2 Kbaud, or to a serial printer for printing logs.
    Port 2 (4PL): Used to interface with an OIT or other terminal's RS-232 port for input and output.

Status Indication

Three status LEDs on the module indicate:

    Top LED: Module status.
    Bottom two LEDs: Serial port activity.

Controls

The module features a pushbutton for control:

    Pressing the button for less than 5 seconds will restart the Alphanumeric Display System software.
    Pressing the button for more than 5 seconds will restore the factory default configuration, allowing communication with the programmer using default settings (without clearing memory).

Batteries

The module uses a lithium battery (IC697ACC701) to maintain user memory when the power is removed. A new battery should be installed in the unused battery connector before removing the old battery. If a low battery is detected during power-up diagnostics, the Module OK LED will not remain on.

The IC697ADC701 Alphanumeric Display Coprocessor is a versatile module designed to manage alphanumeric data display and alarm systems in industrial settings, providing efficient operator interface and communication features.
