Product Overview

The IC693CMM311P is an intelligent Communications Coprocessor module for the GE Fanuc Series 90-30 PLC system. It offloads communication processing tasks from the main CPU, enabling high-speed data exchange without affecting PLC scan performance. The module features two independent serial ports for connection to HMIs, SCADA systems, programming terminals, or other PLCs. This unit is supplied as 100% brand new and original, ensuring reliable and stable industrial communication performance.

Technical Specifications

Engineering Advantages

CPU Load Offloading
Built-in processor handles communication protocol execution independently, reducing CPU workload and maintaining fast control logic execution.

Dual Independent Ports
Each port operates separately, enabling simultaneous multi-protocol communication (e.g., HMI on one port and Modbus RTU on the other).

Industrial Noise Resistance
Supports RS-485/RS-422 differential signaling for strong immunity against electromagnetic interference in harsh industrial environments.

Easy System Integration
Single-slot design allows straightforward installation into Series 90-30 racks without modifying existing cabinet architecture.

FAQs

What is the difference between Port 1 and Port 2?
Both ports support the same protocols, but Port 2 includes additional handshaking signals for certain RS-232 modem applications.

Does it support Ethernet communication?
No. This is a serial-only module. For Ethernet, a separate IC693CMM321 module is required.

What does the “P” suffix mean?
It indicates a hardware revision that is fully backward compatible with earlier IC693CMM311 versions.

Is the unit factory sealed?
Yes. The IC693CMM311P is supplied as 100% brand new, original equipment in factory-sealed packaging.
