IC697CMM711 GE Fanuc Series 90-70 Communications Coprocessor

Product Overview

The IC697CMM711 is a high-performance communication coprocessor module engineered for the GE Fanuc Series 90-70 PLC platform. Equipped with a dedicated 12 MHz 80C186 microprocessor, this module offloads complex serial processing from the main CPU to ensure deterministic logic execution. It features two independent 25-pin D-shell ports that support versatile multi-protocol integration.

Global PLC Spare HUB's Insight

The IC697CMM711 remains a critical asset for engineers managing legacy Series 90-70 architectures. Its primary advantage is the dedicated 80C186 silicon, which ensures that heavy serial traffic does not jitter the PLC scan cycle. While officially discontinued by the OEM, we provide this module in premium condition to ensure your facility avoids downtime. It is particularly effective for peer-to-peer data sharing where deterministic timing is a non-negotiable requirement.

Logistics & Warranty Terms

• Condition: Original equipment in factory-standard protective packaging.
• Warranty: 12-month comprehensive warranty included for peace of mind.
• Handling: Professional testing and dispatch within 24-48 hours.
• Express Shipping: Global priority delivery via FedEx, UPS, or DHL.

Expert FAQ & Selection Guide

• Does the IC697CMM711 support Modbus Master mode?
• No, the IC697CMM711 is restricted to Modbus Slave mode only for RTU protocols.
• Can I configure the ports using physical switches?
• No, this module uses "Soft Configuration" only; settings must be downloaded from the programming software.
• Is it safe to install this module while the PLC is powered?
• Negative. Power must be removed from the baseplate to prevent arcing and potential damage to the VME pins.
• Field Experience Tip:
• If communication fails after a software update, use the front-panel pushbutton to re-initialize the module’s serial buffers.
• Buying Advice:
• Verify your cabling pinouts; the 25-pin D-shell ports often require specific adapters when converting to standard 9-pin RS-232.
