Best regards Anders Dear Anders, What happened to the output Q1, when you gave the pulse to turn off the Q2/Q3/Q4 etc?

There you can find the function FB LGF_PulseRelay. In my opinion is that what you looking for. e.g. You can connect the I6/I7 to the RESET and then can you switch off all the necessary outputs. regards CaOd
