EMERSON IC693CMM302 Series 90-30 Enhanced Genius Communications Module

The Enhanced Genius Communications Module (GCM+), IC693CMM302, is an intelligent module that provides automatic global data communications between a Series 90-30 PLC and up to 31 other devices on a Genius bus. The GCM+ can be located in any standard Series 90-30 CPU baseplate, expansion baseplate, or remote baseplate. However, for most efficient operation, it is recommended that the module be installed in the CPU baseplate since the sweep impact time of the GCM+ module depends on the model of PLC and the baseplate where it is located. Note: if a GCM module is present in a system, GCM+ modules cannot be included in the system. Multiple GCM+ modules can be installed in a Series 90-30 PLC system with each GCM+ having its own Genius bus serving up to 31 additional devices on the bus. For example, this allows a Series 90-30 PLC with three GCM+ modules to exchange global data with as many as 93 other Genius devices automatically.
