Using digital inputs of the LOGO! 8 as monoflop

The monoflop response can be used to map a digital trigger of KNX in the LOGO! 8 direction
as a signal with defined duration.
The monoflop can be retriggered, i.e. the monoflop time is restarted if another trigger signal
is received within the monoflop time.
If the bus voltage returns and the current value of KNX is read and is still set, the monoflop
time restarts.

Monoflop time in ms
The range of values for the monoflop time is 30 to 2500.
Preferred state
The CMK2000 uses the preferred state to determine the initial basic level and the direction
the trigger edges must have so that a trigger is detected.
Example
Input with monoflop response, preferred state = 1, monoflop time = Tm
