3.24 Binary Counts (Function Group COUNT)
The C232 has one binary counter which counts the positive edges at an appropriately
configured binary signal input. The signal to be counted can be debounced.
Enabling or disabling the
counting function
The counting function can be disabled or enabled from the integrated local control panel.
Debouncing
The first positive pulse edge of the signal to be counted starts a timer stage running for
the duration of the set debouncing time. Each positive pulse edge during the
debouncing time retriggers the timer stage. If the signal is stable until the set
debouncing time has elapsed, it is counted.
If the signal has not changed its state from the occurrence of the first pulse edge to the
elapsing of the set debouncing time, it is not counted.
