LFusion2021 Posted February 15, 2021 Report Share Posted February 15, 2021 Hello, This is my first time trying out a Unitronics PLC. I'm trying to use the analog output to simulate a 4 - 20 mA input. I've watched the youtube tutorial, but I'm trying to use a 4 - 20 mA output instead of a 0 - 10 V output. I'm assuming the process would be similar but I can't get it to work. I have attached some photos of the parameters I've set and of the ladder logic. Is this the correct way to adjust the analog output of the plc? Have I set up the linearization table correctly? Currently all that happens is the analog output changes on the screen with the up and down buttons but nothing else. I will test this output with a meter to verify if there is a 4 - 20 mA output being generated. I have connected the 0V to CM (terminal 4) and to appropriate 0V terminals, the A0 output to AN 2 (Terminal 9). Would this be correct? Any help will be greatly appreciated.
