On this picture is the S7400 one-key start and stop function, I have a question as to why I would like to add the SB1Output variable in the rectangle as a condition，
Deleting and not deleting this variable accomplishes the same function，What do you need to consider? I would like to ask you to explain...

Forget this terrible code of an impulse switch.

If you want to know, how you can get this function with a nice code please read the faq:
"Stromstossschalter".

If you need help with the translation, please ask here.
