cRIO-9035 Modbus Registers

Solved!
Go to solution

Have two cRIO-9035s that I would like to connect to PTC Kepware.  That seems pretty straightforward, but I am having a hard time finding documentation that will allow me to understand which registers my I/O is being assigned to.  Does anyone have information on how I can identify the registers so I can pull the information that I need?

Answering my own question, the location of the Modbus registers can be found in this document: cRIO Modbus Slave Reference Library - NI Community
