Overview of Alarms
NCK alarms
27240 PROFIsafe: DP M not running up, DP info: %1
Parameters: %1 = Current information from the DP interface NCK-PLC
Definitions: There is no DP configuration available to the NCK after the time specified via the MD
$MN_PLC_RUNNINGUP_TIMEOUT.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: - Increase MD $MN_PLC_RUNNINGUP_TIMEOUT
- Check the PLC operating status.
- Check the PLC operating system software version.
- Delete the F parameterization in the NCK MD.
Program Switch control OFF - ON.
Continuation:
27241 PROFIsafe: DP M version different, NCK: %1, PLC: %2
Parameters: %1 = DP interface version of the NCK
%2 = DP interface version of the PLC
Definitions: The NCK and PLC components have different implementations of the DP interface. The F
communication cannot be initialized.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: - Check the PLC operating system and NCK software versions.
- Upgrade the PLC operating system.
- Delete the NCK F parameterization.
Program Switch control OFF - ON.
Continuation:
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.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
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 Switch control OFF - ON.
Continuation:
