High-Level Language PCM | Brand New IC697PCM711V GE Fanuc

Product Overview

The GE Fanuc IC697PCM711 (including the IC697PCM711V revision) serves as a powerful Programmable Coprocessor Module (PCM) for the Series 90-70 PLC family. This 100% Brand New original unit functions as an independent computer within the PLC rack, executing complex C-language programs in parallel with the main CPU. By offloading mathematically intensive algorithms, custom communication protocols, and sophisticated data processing tasks, the IC697PCM711 significantly enhances system throughput and enables advanced control strategies that standard ladder logic cannot efficiently handle.

Technical Specifications

Engineering Advantages

• Parallel Processing Efficiency: The IC697PCM711 operates on its own dedicated processor. This architecture allows the module to handle "heavy" computational tasks—such as complex motion profiles or statistical analysis—without increasing the scan time of the main PLC CPU.

• Versatile High-Level Programming: Support for C-language programming unlocks capabilities far beyond traditional PLC instructions. Engineers use this module to develop proprietary algorithms, manage large data arrays, and integrate specialized third-party software routines directly into the control layer.

• Custom Protocol Integration: The onboard RS-232 serial ports enable the creation of custom drivers for non-standard industrial devices. This solves the challenge of interfacing the PLC with legacy barcode scanners, specialized lab equipment, or unique serial sensors.

• Large Capacity Memory Buffer: With 2MB of RAM and 2MB of Flash EPROM, the module stores extensive historical data logs and complex program files. This ensures high-speed access to data without taxing the memory limits of the primary controller.

• Seamless Rack Integration: Designed for the VME-based Series 90-70 backplane, the module communicates via high-speed parallel bus. This eliminates the latency common with external serial-linked processors, providing real-time data exchange with the rest of the I/O system.

FAQs

• Does the IC697PCM711 require a battery to retain its program?

  The module uses 2MB of Flash EPROM for non-volatile storage of user programs. However, the 2MB RAM used for data execution typically relies on the backplane battery or the module's internal power circuitry to maintain volatile data during a power cycle.

• What software is needed to program the IC697PCM711?

  You typically use the GE Fanuc C Programmer's Toolkit or equivalent development environment compatible with the Series 90-70 PCM architecture. Programming occurs through the integrated RS-232 serial port.

• Can I use this module for communication with other PLCs?

  Yes. Many engineers utilize the IC697PCM711 as a communication coprocessor to manage complex data strings or to act as a bridge between the Series 90-70 rack and external computer systems via the serial interface.
