You can find this screen underSafety inputs/outputs > Configuration.
Functions of this screen:
● F-DI discrepancy time (p10002)
The signal states at the two terminals of an F-DI are monitored in order to determine
whether these have assumed the same logical state within the discrepancy time.
Note
The discrepancy time must be set so that it is always smaller than the smallest expected
switching interval of the signal to this F-DI.
● F-DI input filter (p10017)
Parameterization of the debounce time for the F-DIs. A rounded debounce time (to a full
ms) is accepted. The debounce time specifies the maximum time an interference pulse
can be present at an F-DI before being interpreted as a switching operation.
● F-DI selection (p10006 or extended alarm acknowledgment)
The Extended Functions enter a safety message in a special message buffer upon the
detection of internal errors or violations of limits. This alarm can only acknowledged
safely. You can assign an F-DI terminal pair for safe acknowledgment.
