Hello!
I was trying to use RFID tag to sort boxes (odd numbers to one side and even numbers to the other side), but then I found out that there was no output data at RFID sensor even though other sensors worked perfectly. I have two questions: are there any number already assigned to boxes’ tags at all and should I set up RFID sensor somehow beforehand?
I use TIA Portal V15 and 1500-series CPU. I also cheked some sample projects, but could not find what I am doing wrong.
