Sinumerik Alarm 27220 PROFIsafe: Number of NCK F modules (%1) <> number of DP modules (%2)
Parameters:
%1 = Number of parameterized NCK F modules
%2 = Number of parameterized S7 F modules
Definitions:
The number of F modules parameterized via the NCK machine data $MN_PROFISAFE_IN/OUT_ADDRESS is:
• Greater than the number of PROFIBUS slaves in the S7 PROFIBUS configuration.
• smaller than the number of F modules in the S7 PROFIBUS configuration,
• greater than the number of F modules known in the S7 PROFIBUS configuration.
Reactions:
– Mode group not ready.
– Channel not ready.
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
Remedy:
Check the F parameterization in the MD $MN_PROFISAFE_IN/OUT_ADDRESS. Check the F configuration in the Step7 hardware configuration.
Program Continuation:
Switch control OFF – ON.
