Note
Reaction time when powering down
Not every delay time has to be considered in the reaction time of the MSS 3RK3 For example, for
calculating of the reaction time when powering down, a parameterized start delay time can be
ignored because it does not apply in this case.
The parameter for the delay time can be defined as follows:
1. Double-click on the timer function in the work window of the logic diagram for which a delay
time is to be parameterized.
2. Enter an integer multiple of the program cycle time that is suitable for the scope of our
configuration for "Time t1 [ms]" in the "Properties ..." dialog box. Setting range:
10 ms ... 655 s.
Note
Delay time
The delay time must be an integer multiple of the program cycle time. If that is not the case,
MSS 3RK3 rounds down the delay time to an integer multiple of the program cycle time for safety
reasons and Safety ES outputs a warning.
