Overview of Alarms
NCK alarms
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.
Reaction: 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 Clear alarm with the RESET key. Restart part program
Continuation:
27254 PROFIsafe: F module %1, error on channel %2; %3<ALSI>
Parameters: %1 = PROFIsafe address
%2 = Channel type, 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.
The type of channel (input or output channel) is indicated by the abbreviations IN and OUT in %2.
A specific alarm message can be programmed for each of the system variables on the HMI via
parameter %3:
- %3 = 1....64: Error in system variables $A_INSE[1...64]
- %3 = 65...128: Error in system variables $A_OUTSE[1...64]
- %3 = -1: Error in an input or output channel for which there is no SPL assignment
Reaction: 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 wiring. Wiring OK: replace F module.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27255 PROFIsafe: F module %1, general error
Parameters: %1 = PROFIsafe address
Definitions: The specified PROFIsafe module signals an error. A more exact specification of the error's cause
cannot be made without further assistance.
This alarm is triggered for all types of PROFIsafe slaves.
Reaction: 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 wiring.
Program Clear alarm with the RESET key. Restart part program
