Equipment: 1 piece of 6ES7 331-7KF02-,,,,. analog input 1 piece of loop isolator (passive) 1 piece of transmitter (passive) I have the AI set for 2-wire, understanding that the module will then power the loop (and the loop isolator). I connect + from the AI-channel to + on the loop isolator, connect the - from the AI-channel to the - on the loop isolator. I connect the transmitter to + on the loop isolator to the transmitter and the - to the - on the transmitter. But the AI-channel does not get any signal value. Hardware is downloaded and no SF leds are lit. Where is my problem? I do not think to AI is broken, since four circuits behave the same way.
