Assign negative value to register

Posted 23 October 2017 - 03:46 AM

Hi all,

We currently have an analogue input 4-20mA for temperature sensor that reads as 4mA=0C and 20mA=100C. We have now developed a new temperature sensor that reads 4mA= -30C and 20mA=120C. We need to change the 4-20mA settings for temperature sensor. I managed to change the code to read 20mA= 150C but not 120C and thatís probably because I am unable to set 4mA=-30 and it automatically reset it to 0 which makes the span to 120C which is not correct.

Current values : 4-20mA = 0 to 100C
New values : 4-20mA = -30 to 120C

Your help will be needed please. See attached snapshot of how the values are assigned.
