A time measurement is realised with this logic group.
The stopwatch works to the second, but only outputs the measured time in minutes.
The stopwatch is controlled via the "Stopwatch input".

The stopwatch is started with the telegram value "one" and stopped with "zero".

A new telegram at the input with the value "one" while the stopwatch is running resets the measured time but does not stop the stopwatch.

If the stopwatch is stopped, the measured time is retained at the output.

The output is only reset when the stopwatch is restarted.

The second value is always rounded down.
