ON+

Looks for the raising edge of a signal. If your signal is already on, it will still wait at that line, unlike ON.

quoting from handbook about skip condition:

"Off-: The falling edge of a signal is considered a detection condition. The condition is not fulfilled as long as the signal remains off. It is only fulfilled when the signal changes from the ON status to the OFF status.

On +: The rising edge of a signal is considered a detection condition. The condition is not fulfilled as long as the signal remains on. It is only fulfilled when the signal

changes from OFF status to ON status."

Thanks for that, I've just come across some code with these references in, saves me time searching through the manuals for that information now...…….
