IC697CMM711 | GE Fanuc Series 90-70 Communications Coprocessor Module

Product Overview

The GE Fanuc IC697CMM711 functions as a high-performance Communications Coprocessor (CMM) for the Series 90-70 PLC platform. This module offloads heavy serial communication tasks from the main CPU, providing two independent serial ports for interfacing with HMIs, third-party devices, and supervisory systems. It supports a wide array of industrial protocols, including SNP/SNP-X, CCM, and Modbus RTU. We provide this unit in 100% Brand New condition, ensuring peak signal integrity and hardware longevity for your mission-critical legacy infrastructure.

Technical Specifications

Engineering Advantages

• Optimized CPU Performance: The IC697CMM711 utilizes its own 80C186 microprocessor to manage serial framing and protocol handshaking. This dedicated processing prevents serial data traffic from increasing the PLC scan time, maintaining deterministic logic execution even during heavy data polling.

• Multi-Protocol Versatility: This module supports simultaneous operation of different protocols on its two ports. For example, you can configure Port 1 for SNP communication to a local HMI while Port 2 operates as a Modbus RTU slave for a SCADA system, eliminating the need for separate gateway hardware.

• Robust Hardware Interface: The 25-pin D-shell connectors provide secure, industrial-grade physical connections. These ports support RS-422 and RS-485 differential signaling, which effectively rejects common-mode noise in long-distance cable runs across electrically noisy factory floors.

• Instant Resynchronization: An integrated "Restart" pushbutton allows maintenance personnel to re-initialize communication channels without cycling power to the entire PLC rack. This feature drastically reduces downtime during the commissioning of new serial device networks.

FAQs

• Can the IC697CMM711 act as a Modbus Master?

  No. The IC697CMM711 supports Modbus RTU in Slave mode only. If your application requires the Series 90-70 to initiate commands to third-party Modbus devices, you should consider a Programmable Coprocessor Module (PCM) or a newer RX7i upgrade.

• Does this module require a battery for configuration storage?

  The IC697CMM711 does not require an internal battery. It receives its configuration parameters directly from the CPU during the system power-up sequence, ensuring the module remains maintenance-free for its entire service life.

• What is the purpose of the three LED indicators?

  The "OK" LED confirms the module passed its internal power-up self-test. The "PORT 1" and "PORT 2" LEDs flash to indicate active data transmission or reception on the respective channels, providing immediate visual confirmation of network health.

• Is this a refurbished or "pulled" unit?

  No. We guarantee this IC697CMM711 is 100% Brand New original stock. This is critical for communication modules, as used serial ports often suffer from driver chip degradation or damaged connector pins that cause intermittent "Time-Out" errors.
