Blocks for time functions

Note
Higher energy consumption due to additional update cycles
Time functions can generate additional update cycles to update the outputs of the function.
Additional update cycles can significantly increase power consumption.
5.6.1

On delay

Function
When there is an edge change 0 → 1 at the "Trigger" input, the configurable time of the On
delay is started. After the On delay has elapsed, the output is set to 1.
If "Trigger" changes back to 0 before the On delay has elapsed, the On delay is stopped and
the output remains set to 0.
If "Trigger" is reset to 0 before the On delay (Q = 1) has elapsed, the output (Q) is reset to 0.
