hi azizmustofa8, When you using a converter, you are measuring the current from the converter, not the PT100 itself. I assume the converter has an additional power-supply. that means you have a 4-wire-transducer (2wire for measuring, 2wire power-supply). set your measurement range module to C. wiring is described here: Analog input module SM 331; AI 8 x 12 bit;(6ES7331-7KF02-0AB0) hope this helps, regards, |
