Hello,
I am trying to connect a dosing unit 4 ( 11110974014) to the profilux. I have put the cable into S1-4 en have tried to tell the profilux has to use socket 7-10 one a timing function. So far so good. I disconnect the pab cable form te powerbar( not form the touch screen) and follow the steps as told in topic

The dosing unit is not communicating with the profilux or the other way around.
what i am doing wrong?
