Modbus device voltage reading inconsistency

Hi,

I have a modbus device that is currently working but it is giving me inconsistent readings. The modus device has thermocouples that I am reading as a shared variables that outputs voltage readings.  I am subtracting the voltage reading that corresponds to to 0 degrees from the shared variable reading and multiplying a calibration constant to convert the voltage readings to temperatures. I can't figure out why the readings are inconsistent.  I have attached the program for better understanding of the system. Any suggestion on what to do. Thank you for your time.

Hi Abdi!

 

I think you forgot to attach your VI Smiley Happy

 

What do you mean by inconsistent readings?  Do they change erratically?


Regards,

Peter D
