15.5.1.1 Timer – Time Constant
The logic sequence of input and output signals is to be set separately for both timer
functions via the time constants. The default parameter values
result in a direct link
of the input and output signal without a delay.
Before starting the timer, select the operation mode and set the time constants in or-
der to avoid non
-defined states.
Select operation mode for:
Set time constants in:
Operation Mode Timer 1 790
Time 1 Timer 1 791 (signal delay)
Time 2 Timer 1 792 (signal duration)
Operation Mode Timer 2 793
Time 1 Timer 2 794 (signal delay)
Time 2 Timer 2 795 (signal duration)

Examples of the timer function depending on the selected operation mode and the
input signal:
Normal, positive edge
Parameter Operation Mode Timer 1 790 or Operation Mode Timer 2 793 = 1
As soon as the positive signal edge is received at the input, time 1 (signal delay)
starts. After the expiry of time 1 (signal delay), the output signal is switched on for
time 2 (signal duration).
In the settings of signal duration (Time 2 Timer 1 792 = 0 and Time 2 Timer 2 795
= 0) the timer does not reset the output signal.
Retrigger, positive edge
Parameter Operation Mode Timer 1 790 or Operation Mode Timer 2 793 = 2
As soon as the positive signal edge is received at the input, time 1 (signal delay) is
started. If a positive signal edge is detected within time 1(signal delay), time 1 starts
again. After the expiry of time 1 (signal delay), the out
put signal is switched on for
time 2 (signal duration).
In the settings of signal duration (Time 2 Timer 1 792 = 0 and Time 2 Timer 2 795
= 0) the timer does not reset the output signal.
