Note
Support by Safety ES
Safety ES helps you con󹪝gure the program cycle time. The "status bar" shows the current
utilization of the parameterized program cycle time.
Parameterizing the input delay time t
DELAY
in Safety ES
WARNING
Increasing the reaction time
can cause death, serious injury, or damage to property.
If the input delay increases, the reaction time of the safety program increases.
The parameter for the input delay time can be de󹪝ned as follows:
1. Double-click the monitoring function/input cell in the work window of the logic diagram for
which an input delay time is to be parameterized.
2. Enter a value between 0 ms and 150 ms for "Input delay [ms]" that is suitable for the scope
of your con󹪝guration in the "Central unit properties" dialog box.
Note
Input delay
The input delay time must be an integer multiple of the program cycle time. If that is not the case,
MSS 3RK3 rounds down the input delay time to an integer multiple of the program cycle time for
safety reasons and Safety ES outputs a warning. If you use safety-related AS-i input terminals, the
smallest settable input delay time is 50 ms.
Parameterizing the delay time t
TIMER
in Safety ES
In Safety ES there are various timer functions with which delay times can be parameterized in the
logic:
• With ON delay
• With ON delay (trigger)
• Passing make contact
• Passing make contact (trigger)
• With OFF delay
• With OFF delay (trigger)
• Clocking
