Functional Description

IC697PCM711 is a Programmable Coprocessor Module developed by GE. It is a high-performance Programmable Coprocessor Module (PCM) designed by GE to enhance the functionality of programmable logic controllers (PLCs) in industrial automation. This module is ideal for tasks requiring additional processing power, data management, and communication capabilities. Equipped with advanced features, it efficiently handles data acquisition, storage, and communication functions within PLC systems, making it a versatile choice for complex industrial applications.

Features

• Single Slot Coprocessor: The PCM occupies just one slot in the PLC rack, optimizing space for other modules.
• Dual Tasking: This module supports dual-task operations, allowing it to perform multiple tasks simultaneously, increasing operational efficiency.
• MegaBasic Support: The MegaBasic programming language provides a robust environment for developing custom applications.
• CCM2 Protocol: Ensures reliable data communication.
• 12 MHz, 80C186 Microprocessor: Delivers high-speed processing, achieving 90% of the performance of an IBM AT computer.
• Expandable Memory: Up to 96 KB of battery-backed memory, with optional expansion of up to 512 KB.
• Two Serial Ports: Supports RS-422/RS-485 or RS-232 interfaces for flexible connectivity.
• Real-Time Calendar Clock: Synchronizes with the PLC’s internal clock, providing accurate timing for applications.
• Soft Configuration: Eliminates the need for DIP switches or jumpers, allowing configuration through MS-DOS or Windows-based software.
• Reset and Status LEDs: The PCM includes a reset button and three LEDs to indicate operational status.

Functions and Capabilities

The Module enhances the functionality of PLC systems by performing data storage, data acquisition, and communication tasks independently. It connects directly to the PLC CPU via the backplane, enabling seamless access to both user and system data using the MegaBasic language. Multiple PCMs can be installed within a single IC697 PLC system, and each PCM can accommodate expansion memory of up to 512 KB, further boosting the system's data-handling capacity.

Installation Process

• Power Off the Rack: Ensure that the PLC rack’s power is switched off before installation.
• Install Expansion Memory: If additional memory is needed, install the expansion memory daughter board.
• Battery Connection: Connect the battery to one of the module’s battery connectors to enable data retention.
• Rack Installation: Insert the PCM module into the designated slot in the rack.
• Power On: Switch on the rack power. The top LED on the module should blink initially and then remain steady to indicate successful diagnostics.

Expansion Memory Options

It can operate with or without an expansion memory daughter board. The onboard base memory provides up to 96 KB of user memory, while the expansion memory allows for additional storage options of 64, 128, 256, or 512 KB. The battery on the base board supports the expanded memory, preserving data in the event of a power outage.

Programming and Configuration

Programming and configuring the IC697PCM711 requires compatible PCM Development Software installed on an IC647, IC640, or IBM-compatible PC. The software enables users to configure serial port parameters, interface definitions with the PLC CPU, and task functions, along with programming MegaBasic applications. The default communication speed is set to 19,200 bps, and the module can be configured using either MS-DOS® or Windows®-based software.

Configuration

It does not rely on physical switches or jumpers for user configuration. Instead, all configuration tasks are completed through the PCM Development Software, streamlining the setup process and minimizing manual adjustments.

Status Indications

The PCM includes three status LEDs to assist with operational monitoring. The top LED indicates the module’s overall condition, while the lower two LEDs can be assigned custom functions based on the specific application requirements.

Control Functions

The module has a single pushbutton control. Holding the button for under five seconds restarts the application, while holding it for over five seconds resets the module to its factory default configuration. This action enables communication with the programmer using default settings without clearing the module's memory.
