Emerson FM-2 Indexer Modbus Codes?

Hello:

I've been given the task of troubleshooting a system that contains an Emerson FM-2 servo indexing module/ An AB Micrologix 1200 and a RedLion CL20 HMI.

The RedLion is communicating w/ the FM-2 over Modbus and using some code (for instance 32042) to read/write to different parameters in the drive. While Emerson seems to have all kinds of manuals on line and free software too I'm having some trouble locating the list of these modbus codes.

Has anyone done this before and could possible point me in the right direction here to the secret codes?>....

Thanks

Here's a link to the drive parameters manual for the FM-2,Ei, and Ei-DN drives Here

That's exactly what I needed!!!

Thanks
