Hi, I have a CPU314 with an analog input card that sets to 0-10VDC input.
I inject the voltage from a multimeter but it does not showing any reading on TIA Portal V17. We tried on all channels but still fail to get any reading. We suspect AI cards faulty, wrong configuration, wiring mistakes etc.
So we recreate the program in Simatic Manager V5.7, same wiring, same card, same hardware configuration etc. But this time we able to get the reading.
Any idea why it can work in Simatic Manager but not on TIA Portal?
