We are communicating with multiple CAT EMCPII units via a CCM connected to a GE Fanuc 90/30 PLC. We had a driver written for firmware installed in a PCM (Programmable Coprocessor Module) of the PLC. The PLC program polls data every 1-5 seconds (configurable) and provides for interrupt write capability to the controllers. The driver is commercially available through the developer, http://www.selahgroup.com/. It is solid and their documentation is very good.
Cat also sells an inexpensive software package that is Windows-based for interface to the CCM. The protocol is Cat MX-5 (proprietary).
Hope this helps,

Wonderware supports the CCM protocol(usually referred to as CCM-2) directly. For a performance boost, install an ethernet card into the 90/30 and connect up to wonderware.

There is a DDE server that is designed to communicate via RS-232 to a CCM available from Streamline Integrated Solutions at streamlineaz.com. It was written by Dave Stutt. We have successfully used it with Intouch 7.0 SP2 on NT 4.0 SP5.
If you only need alarms you can use a Caterpillar CIM (A relay output board providing form C relay contacts.)

Steve Braun's company wrote several drivers for Selah Group, but they did not write the CAT CCM MX-5 protocol driver, it was written by an individual not associated with Steve's company. The Selah Group folks worked with the developer on the Cat CCM programming. In fact, Selah Group had a Modbus driver written by the same programmer (not assoc. with Steve Brauns company), added much better functionality and documentation and we have since replaced most of our Steve Braun firmware with the improved Selah Group firmware in our systems. It is much easier to use and provides better health monitoring of the modbus interface. You should look into it.
