Programmable Coprocessor Module for Series 90-70 PLC Systems

The GE IC697PCM711G functions as a programmable coprocessor module for the Series 90-70 PLC platform. This module offloads complex computational tasks from the main CPU for enhanced system performance. Its design supports real-time data processing and custom algorithm execution in industrial automation applications.

Processing Architecture and Memory Configuration

This coprocessor module features an Intel 80186 processor running at 16 MHz for efficient program execution. The PCM provides 256 KB of user memory for application code and data storage. It supports C programming language for sophisticated algorithm development. Moreover, the module includes battery-backed RAM for program retention during power loss. Consequently, this module handles intensive computational tasks effectively.

Communication and Interface Capabilities

The IC697PCM711G provides a standard RS-232/RS-485 serial port for external device connectivity. The module also includes an expansion port for additional memory or communication modules. It communicates with the Series 90-70 backplane via a dedicated bus interface. Furthermore, the serial port supports ASCII protocol for bar code readers and printers. For this reason, this coprocessor offers flexible connectivity for peripheral devices.

Diagnostic and Physical Specifications

This programmable coprocessor includes front-panel LEDs for status monitoring. The module occupies a single slot in the Series 90-70 rack. It operates reliably across a temperature range from 0 °C to 60 °C. Additionally, the module draws standard backplane power from the +5 VDC supply. Consequently, this coprocessor provides robust computing capability for Series 90-70 systems.
