Features:
- Automatic Genius global-data exchange
- Up to 128 bytes transmitted per bus scan
- Communication with up to 31 other Genius devices
The IC693CMM302 ordering number designates the enhanced GCM+ rather than the earlier fixed-address GCM.
Its primary role is automatic data sharing between a Series 90-30 CPU and peer Genius devices without application-driven message transactions.
Before adding the module, verify the CPU release, baseplate, programming software, permitted module quantity, bus address, and configured data ranges against the applicable official documentation.
The GE IC693CMM302 Enhanced Genius Communications Module (GCM+) is listed as Active / Available from OEM. Contact Apter Power for documentation and Genius bus review.
