display correct temperture value from modbus registers
« on: April 06, 2015, 10:11:21 PM »
I am reading Modbus register for example 40001  and 40002 for temperature < it comes from a control logix  floating point which is 32 bit and has to be split into two  16 bits words to transmit over modbus , my question is how can I put it back together and display the correct value in a digital panel meter.

Why are you not using the ControlLogix driver?

I'm using some of my HMI's as a trouble shooting tool to test registers from a prosoft card in a control logix rack , I have found that any hick up in comms is picked up very easily using AHMI
