5.4.5 TIMER operators
1
The “TIMER” operators enable a signal (logic “1” or logic “0”) to be generated during a time
period defined by the user.
5.4.5.1 MONOSTABLE operator
The “MONOSTABLE” operator generates the logic “1” state of an output that is activated by
a rising edge at input “I
N” and remains in this state for at least the specified time period.

Parameters
Time A delay between 10 ms and 1093.3 s can be entered.
Scale – 0.01 s ... 60.0 s (in 10 ms increments)
– 60.1 s ... 1098.3 s (in 100 ms increments)
Retriggerable When this option is selected, the time is reset to zero on every status change of the “I
N” in-
put.
Rising Edge If this parameter is selected, the “O
UT” output is set to logic “1” on a rising edge at the “IN”
input and remains in this state for the parameterized time, even in the event of a signal
change at the input. If the input signal is present for longer than the parameterized time, the
output signal is only set to logic “0” when a falling edge occurs at the “I
N” input.
