GE IC697CMM711 – Communications Coprocessor Module | Series 90-70 PLC Platform
Engineering Background
The GE IC697CMM711 is a dedicated Communications Coprocessor Module engineered for the GE Series 90-70 programmable logic controller (PLC) platform — one of the most widely deployed rack-based control architectures in heavy industrial environments. Designed to offload serial communication tasks from the CPU, this module enables deterministic, high-throughput data exchange across multi-drop networks without impacting scan cycle performance.
Product Positioning
Targeted at procurement engineers and system integrators managing legacy Series 90-70 installations, the IC697CMM711 is the authoritative solution for extending or maintaining serial communication capability in existing control panels. Konmask.com supplies this module as a verified OEM or factory-refurbished unit, fully tested and ready for immediate deployment.

Engineering Advantages
- CPU Offload: Dedicated coprocessor handles all serial communication tasks independently, preserving CPU scan time for control logic.
- Dual-Port Flexibility: Two independently configurable serial ports allow simultaneous connection to different networks or protocols.
- Protocol Versatility: Native support for SNP/SNP-X enables seamless integration with GE HMIs (CIMPLICITY, iFIX) and third-party SCADA systems.
- Backward Compatibility: Drop-in replacement for existing Series 90-70 racks — no hardware modification required.
- Deterministic Performance: Guaranteed message response times critical for real-time process control loops.
System Architecture & Signal Flow
The IC697CMM711 occupies a single slot in the Series 90-70 rack and communicates with the CPU module via the VME backplane. Serial data from field devices enters through Port 1 or Port 2 (DB-9 connectors), is processed by the onboard coprocessor, and is transferred to the CPU’s data table via shared memory on the backplane. Configuration is performed through the GE Proficy Machine Edition (PME) or Logicmaster 90-70 programming software. The module supports both point-to-point and multi-drop topologies, with baud rates configurable from 300 bps to 19,200 bps.

Technical FAQ
Q: Is the IC697CMM711 compatible with all Series 90-70 rack sizes?
A: Yes. It is compatible with all standard Series 90-70 racks (5-slot, 9-slot, 12-slot) and requires no special slot position.
Q: Can this module communicate using Modbus TCP?
A: No. The IC697CMM711 supports serial Modbus RTU only. For Modbus TCP, consider the GE IC697CMM742 Ethernet module.
Q: What programming software is required for configuration?
A: GE Proficy Machine Edition (PME) v8.0+ or Logicmaster 90-70 v9.05+. Configuration is stored in the CPU program and downloaded to the module at runtime.
Q: Is firmware upgrade supported in the field?
A: Yes. Firmware can be updated via the serial port using GE’s firmware upgrade utility. Contact Konmask for the latest firmware file.
Q: What is the lead time for bulk orders (>5 units)?
A: Typically 5–10 business days depending on stock. Contact us for volume pricing and consolidated shipping options.
