NewToUnitronics Posted March 22, 2018 Report Share Posted March 22, 2018 Hello I just bought a Unitronics M91-2-UA2 PLC. I am trying to program the analog I/O, but I cant get them to talk together. I have a loop calibrator on the analog input 4-20ma. On the analog output i have a multimeter that i can recieve 4-20ma. The problem is when i give the input 4ma, the output showa 16ma. When I adjust the input to 8ma, the output shows 12ma... Can anyone help me with the ladder diagram to get the output to communicate with the input.
