Overview of Alarms
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality.
Remedy: Check the DP wiring. Restart F slave modules. Restart the NCK/PLC.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27252
PROFIsafe: Slave %1, sign-of-life error
Parameters: %1 = DP slave address
Definitions: The specified DP slave no longer communicates with the master.
Reactions: - Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality.
Remedy: Check the DP wiring. Restart F slave modules. Restart the NCK/PLC.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27253
PROFIsafe: communication fault F master component %1, error %2
Parameters: %1 = Error component (NCK/PLC)
%2 = Error code
Definitions: The F master signals that the communication between the NCK and PLC is no longer
working.
The error code %1 specifies the cause:
• %1 = NCK: Link between PROFIsafe and SPL interface is interrupted.
• %1 = PLC: the PLC does no longer execute the OB40 request.
• %1 = PLC-DPM: DP master is no longer in OPERATE status.
Parameter %2 provides further information about the error's cause:
• %2 = 0: NCK-internal sequence error (see %1=NCK).
• %2 = 1,2,4: PLC processing of the OB40 not finished.
Reactions: - Mode group not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Trigger a STOP D/E (settable via MD $MN_SPL_STOP_MODE) on all axes with safety
functionality.
Remedy: Extend the PROFIsafe cycle time via MD $MN_PROFISAFE_IPO_TIME_RATIO.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27254
PROFIsafe: F module %1, error on channel %2; %3<ALSI>
Parameters: %1 = PROFIsafe address
%2 = Channel number
%3 = System variable array index extension
Definitions: The F module signals that an error occurred in the interface of the specified channel.
This alarm is only triggered for ET200S F modules.
%2=0: Special meaning: A general error occurred in the F module.
