Counter block
The "COUNTER" block increments the internal counter value in the event of a positive edge
at the input.
The maximum counter value is 2. The counter value is reset in the event of an overflow:
0 → 1 → 2 → 0
●
Counter value 0 → output Q30 active
●
Counter value 1 → output Q31 active
●
Counter value 2 → o
utput Q32 active
After the controller has been switched on, the counter value is initialized automatically with 0.
You can reset the counter value to 0 via the "reset" input. As long as the "reset" input is
active, the counter value is 0.
