Overview Staircase delay

This function block implements a so-called "staircase function", for example a staircase or corridor light with two switches at the beginning and end of the staircase / corridor. At the beginning the light is switched on with a pushbutton; after a certain time the light is switched off automatically. Unlike, for example, an off-delay, with this function block the output can also be switched on or off again manually, for example at the end of the corridor.
