Brand New GE IC697CMM711 Series 90-70 Coprocessor

Product Overview

The GE Fanuc IC697CMM711 functions as a dedicated communications engine for the Series 90-70 PLC platform. This 100% Brand New original coprocessor offloads intensive protocol management from the main CPU, allowing the controller to focus exclusively on logic execution. By handling CCM, TCP/IP, and SRTP protocols independently, the IC697CMM711 ensures high-speed data throughput between the PLC and external devices such as HMIs, SCADA systems, and networked controllers. It serves as a vital bridge for integrating legacy Series 90-70 hardware into modern distributed control architectures.

Technical Specifications

Engineering Advantages

• CPU Resource Optimization: The IC697CMM711 features its own onboard processor to manage complex communication stacks. This "Coprocessor" architecture prevents communication-heavy tasks—such as processing TCP/IP packets or CCM requests—from extending the PLC scan time, maintaining deterministic control performance.

• Protocol Versatility: This module supports a wide range of industrial standards, including the proprietary CCM protocol and standard SRTP/TCP/IP. This flexibility allows the Series 90-70 to communicate simultaneously with legacy GE hardware and modern Ethernet-enabled devices.

• Enhanced Electrical Isolation: Each communication port incorporates optical isolation. This engineering safeguard prevents high-voltage transients or ground loops from migrating into the PLC rack, protecting the logic circuitry from the unpredictable electrical noise found in factory and utility environments.

• Dual-Port Flexibility: The dual RS-232/RS-485 serial interfaces allow for multi-drop or point-to-point configurations. Engineers can link the PLC to a local HMI while simultaneously maintaining a long-distance serial connection to a supervisory SCADA system.

• Real-Time Diagnostic Feedback: The front panel includes high-visibility status LEDs. These indicators provide immediate confirmation of module health and port activity, allowing field technicians to identify network bottlenecks or hardware faults without opening a programming terminal.

FAQs

• Q: Does the IC697CMM711 require special software for configuration?

• A: Yes. You configure the module through the standard GE programming software (Logicmaster 90 or Proficy Machine Edition). You must set up the communication parameters, such as baud rates and station IDs, to match your external network nodes.

• Q: Can this module replace a standard CMM711 in an existing rack?

• A: Yes. The IC697CMM711 is a direct drop-in replacement for legacy CMM711 units. Being Brand New original stock, it offers improved reliability and firmware stability compared to refurbished or surplus units.

• Q: Does the Ethernet port support 100 Mbps or Gigabit speeds?

• A: No. As a module designed for the Series 90-70 platform, its Ethernet interface operates at 10 Mbps. While slower than modern gigabit modules, it provides more than sufficient bandwidth for industrial PLC data exchange and SCADA polling.

• Q: What is the benefit of using CCM protocol today?

• A: CCM (Communications Control Module protocol) remains a highly reliable and deterministic protocol for GE systems. Using the IC697CMM711 for CCM allows you to maintain stable links with existing GE legacy equipment while utilizing the module's newer ports for modern network integration.
