Order now IC697CMM711 GE Fanuc Series 90-70 Communications Coprocessor Module
Order now IC697CMM711 to revolutionize the data transfer and communication capabilities of your Series 90-70 Programmable Logic Controller. The GE Fanuc IC697CMM711 is a high-performance Communications Coprocessor Module (CMM) designed to offload intense communication tasks from the main CPU, ensuring that your PLC’s logic sweep time remains completely unaffected by heavy network traffic. Operating as an intelligent, microprocessor-based VME module, the IC697CMM711 provides two fully isolated, high-speed serial ports that can be individually configured for RS-232, RS-422, or RS-485 physical interfaces. By integrating this genuine OEM component, your automation infrastructure gains the ability to interface seamlessly with a wide variety of third-party devices, including barcode scanners, specialized industrial scales, remote operator interface terminals (HMIs), and supervisory control and data acquisition (SCADA) systems. The module natively supports industry-standard protocols such as SNP, SNP-X, Modbus RTU slave, and custom ASCII communication, making it an indispensable asset for factories looking to upgrade their data logging and machine-to-machine (M2M) connectivity without sacrificing core processing speed.

Expert Installation and Networking Advice
When deploying the IC697CMM711 in a harsh industrial environment, electrical noise is the primary enemy of serial communication. It is critical to utilize high-quality, heavily shielded cables for all RS-485 network runs. An expert recommendation is to terminate the RS-485 network properly at both ends with a 120-ohm resistor to prevent signal reflection, which can lead to dropped data packets and communication timeouts. Furthermore, the two ports on this module are configurable via software, but ensure the physical dip switches or jumper settings on your breakout cables match the logic configuration in your GE Fanuc programming software (Logicmaster or Proficy Machine Edition). Always route these communication cables away from high-voltage motor feeds and variable frequency drives (VFDs) to maintain the absolute integrity of your data transmission.
Frequently Asked Questions (FAQs)
How do I configure Port 2 for Modbus RTU slave communication? Configuration is handled entirely through the hardware configuration tool in your GE Fanuc programming software. You must select the IC697CMM711 from the module catalog, double-click the specific port, change the protocol drop-down to Modbus RTU, and define the station address, baud rate, parity, and stop bits to match your SCADA master device.
Can the IC697CMM711 be installed in an expansion rack? Yes, this Communications Coprocessor Module can be installed in either the main CPU rack or a remote expansion chassis, providing maximum flexibility in how you design your physical factory layout and wire your peripheral devices.
Does this module require its own battery? No, the IC697CMM711 draws its operating power and logic configuration directly from the Series 90-70 VME backplane. It does not contain battery-backed SRAM, as all configuration data is pushed to it by the main CPU upon power-up.
