Sinumerik Alarm 27242 PROFIsafe: F module %1, %2 faulty

Parameters:
%1 = PROFIsafe address
%2 = Incorrect F parameter

Definitions:
An error was detected during the evaluation of the F parameters.
%2 = CRC1: CRC specified by F parameters faulty.
%2 = F_WD_Timeout: The monitoring time parameterized in Step 7 is too small for the PROFIsafe cycle time defined by the MD $MN_PROFISAFE_IPO_TIME_RATIO.
%2 = CRC2_Len: CRC message length faulty.
%2 = F_Data_Len: the telegram length defined for the specified module is incorrect.

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:
%2 = CRC1: PLC overall reset, reload the S7 F configuration.
%2 = F_WD_Timeout: reparameterize the PROFIsafe cycle time or F monitoring time.
%2 = CRC2_Len: PLC overall reset, reload the S7 F configuration.
%2 = F_Data_Len: PLC overall reset, reload the S7 F configuration.

Program Continuation:
Switch control OFF – ON.
