The task of this logic group is to prevent a KNX device from being repeatedly switched on and/or off within a specified time.

When the logic group is activated, the "Gate object" element is activated first with the "Initialise" element. For this purpose, the value TRUE is sent to the GATE input, thus enabling the gate object to directly forward the first telegram received.
The "Lock door object" element (staircase timer) is also triggered via the output of the door object. The debounce time can be changed as desired via the input of the same name.
In the next step, the "Lock door object" element (staircase automat) is triggered and the door element is locked for the following telegrams for 3 seconds via an inverter.
After 3 seconds, the Staircase automation element sets the GATE of the gate element to TRUE again and allows the next telegram to be forwarded to the output.
The status of the gate object is indicated via the "Locked?" output.
