On one of my machines there is a 1756-IF16 analog input module in use. A gas detector that has a 4-20mA output is to be wired to it. When we checked the range in Studio5000 the scale of the numbers goes from -32768 to positive 32768 from 0 - 20mA.
Does anybody have a good way to go about converting the negative side of the range to a positive so that i can do scaling and alarms. I was hoping to get it to read 0 at 0mA and around 65536 at 20mA after any conversion is done. Ive played around with some logic to try and scale it but have been unsuccessful.
