PRODUCT INFORMATION
Product Overview
The General Electric IC693CMM302 is an Enhanced Genius Communications Module designed for the Series 90-30 programmable logic controller family. This single-slot module functions as an enhanced Genius communications device, also designated as a GCM+ unit. It establishes a dedicated Genius bus connection capable of communicating with up to 31 additional field devices. Host controllers support up to two IC693CMM302 modules simultaneously, expanding addressing capacity up to 62 remote bus devices per controller.
Operating on an internal backplane current draw under 300 mA at 5 VDC, the module handles deterministic data transactions. It manages 128 bytes of transmitted global data alongside 128 bytes of received global data per unit. Memory compatibility spans global registers, discrete inputs, discrete outputs, analog inputs, analog outputs, and internal register memory. The module also facilitates industrial computer data monitoring, peer-to-peer data exchange, master-slave communication, and Genius block monitoring.
