GE FANUC IC693CMM302 , Enhanced Genius Communications Module , Series 90-30 PLC

Product Description

The GE Fanuc IC693CMM302 is an Enhanced Genius Communications Module. It is quite commonly know as GCM+ for short. This unit is an intelligent module which enables automatic global data communications between any Series 90-30 PLC and up to a maximum of 31 other devices. This is done on a Genius bus. It is possible for the IC693CMM302 GCM+ to be installed on a number of different baseplates, including expansion or remote baseplates. That being said, the most efficient performance of this module can be achieved by installing it in the CPU baseplate. This is because the sweep impact time of the module is dependent on the PLC model and varies according to which baseplate it is located in.

Users must note that if a GCM module is already present within a system, they will not be able to implement the GCM+ module. It is actually possible to have multiple GCL+ modules in a single Series 90-30 PLC system. Each GCM+ module can have its own separate Genius bus. In theory, this would enable a Series 90-30 PLC (with three GCM+ modules installed) to automatically exchange global data with up to 93 other Genius devices. Additional uses for the IC693CMM302 GCM+ module include data monitoring of PCs or industrial computers and peer-to-peer communications between devices on the bus. On the front of the IC693CMM302 GCM+ unit, there are LEDs to show the operating status. These will be switched on if everything is operating normally. The LED marked COM will blink intermittently if there any bus errors. It will turn off if the bus has failed.

The Series 90-30 IC693CMM302 communication module was designed and manufactured by GE Fanuc to be a GCM+ device, also known as an enhanced Genius communications module. The IC693CMM302 enhanced Genius communications module can communicate with global data between up to 32 devices. These devices are a GE Series 90-30 PLC and 31 other devices that are connected to a genius bus. It is recommended to install the IC693CMM302 enhanced Genius communications module on the CPU baseplate of the host PLC system for the most efficient operation, but it can also be installed on the remote baseplates or the expansion baseplates in the same system. However, enhanced Genius communications modules cannot be installed in PLCs that have regular Genius communications modules or GCMs in them.

Multiple enhanced Genius communications modules like the IC693CMM302 module can be installed in a single PLC system, and each enhanced Genius communication module has its own genius bus, which means that each of these modules can connect to and communicate with up to 31 additional devices at a time. For example, a Series 90-30 GE PLC that has 2 enhanced Genius communications modules in it can communicate with as many as 62 additional devices at a time. The IC693CMM302 enhanced Genius communications module is primarily used to exchange global data, but it can also handle data monitoring with an industrial or personal computer, peer-to-peer communication and master-slave communication between the bus devices, and data monitoring from the genius I/O blocks (note that the communications module cannot control these I/O blocks.)
