Eurotherm 815 Modbus which I/O items refer to the SP, PV, etc and how do i access them

I'm writing a labview vi to access the SP,PV and ramp rates etc on a Eurotherm 815 Temperature controller.

I'm using Modbus to acess the eurotherm. Have created an I/O server and a list of items has appeared.  I'm not sure which items refer to the eurotherm parameters

and how to comunicate with them/

I've added a pic so u have an idea what i'm talking about. I need help detemining which i/o items refer to to which parameter mnemonics.

Any help would be appreciated
