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)
Parameter Settings
No. Description Min. Max. Fact. sett.
791 Time 1 Timer 1, signal delay 0.00 s/m/h 650.00 s/m/h 0.00 s/m/h
792 Time 2 Timer 1, signal duration 0.00 s/m/h 650.00 s/m/h 0.00 s/m/h
794 Time 1 Timer 2, signal delay 0.00 s/m/h 650.00 s/m/h 0.00 s/m/h
795 Time 2 Timer 2, signal duration 0.00 s/m/h 650.00 s/m/h 0.00 s/m/h
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 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.
