148 Operating Instructions ACTIVE 06/07
The sources of the digital signals (e.g. 73-S4IND, 175-Digital signal 1) are selected via
the parameters
Timer 1 83 and Timer 2 84. Timer 1 is linked to digital input 4 and
Timer 2 is linked to the logic signal digital signal 1.
The output signal of the timer can be assigned via the corresponding parameters of
the operation mode of a digital input or output. By default,
Data Set Change-Over 1 is
linked to Timer 1 and
Digital Output 1 530 is linked to Timer 2.
14.5.1.1 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.
Note: Before starting the timer, select the operation mode and set the times in
order to avoid non-defined states.

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

Time 2
Time 1
As soon as the positive signal edge is received at the input, time 1 starts. After the
expiry of the delay, the output signal is activated for signal duration time 2.
