9.8.5 On-delay timer
Function block diagram
General description
The On-delay timer function block delays the switching-on of the output signal by a
specified duration.
Parameters of the function block
Parameter Possible values
Delay time 0 = disabled.
0 to 300 seconds in steps of 10 ms.
If the value is not 0, it has to be greater than the logic execution time.
The timer begins with the delay sequence when a rising edge (Low to High) on the
input occurs. If the timer has expired after the configured delay period, the
Enable
output changes also to High, provided the input remains High. If the input changes to
Low, the
Enable output is set to Low immediately and the delay timer is reset.
