27220 PROFIsafe: Number of NCK-F modules (%1) <> number of S7-F modules (%2)
Parameter %1 = number of parameterized NCK-F modules
%2 = number of parameterized S7-F modules
Explanation The number of F-modules parameterized using the NCK machine data MD10386/10387 $MN_PROFI‐
SAFE_IN/OUT_ADDRESS is:
● greater than the number of PROFIBUS slaves in the configured S7 PROFIBUS
● less than the number of F-modules in the configured S7 PROFIBUS
● greater than the number of F-modules in the configured S7 PROFIBUS
If the specified number of S7 F-modules = 0, then none of the F-modules, configured in the S7-PROFIBUS
configuration were found.
Generally, the cause of this alarm is an error in the parameterization of the PROFIsafe master address.
