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 can-
not 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
27256 PROFIsafe: Current cycle time %1 [ms]> parameterized cycle time
Parameters: %1 = Current PROFIsafe communication cycle time
Definitions: The current PROFIsafe communication cycle time is greater than the value set via MD
$MN_PROFISAFE_IPO_TIME_RATIO. The parameterized PROFIsafe communication cycle time is
continually exceeded on the PLC side.
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: Adapt cycle time via MD $MN_PROFISAFE_IPO_TIME_RATIO.
The value displayed in parameter %1 has to be set at least.
The set cycle time affects the runtime load of the PLC module. This also has to be taken into consid-
eration when making the setting.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
27257 PROFIsafe: %1 %2 reports system error %3 (%4)
Parameters: %1 = Type of communication
%2 = PROFIsafe address
%3 = Error code
%4 = Component
Definitions: A system error has been detected in the PROFIsafe communication. Depending on the error, the rel-
evant PROFIsafe driver or the entire PROFIsafe communication will be stopped.
In %1 the communication type is displayed
%1 = F module
%1 = SPL
%2 = PROFIsafe address of the affected F module (with %1 = F module)
%2 = - (with %1 = SPL)
In %3 the detected error cause is displayed:
%3 = SF: Asynchronous error state (StateFault)
%3 = SP: No update of the SPL input/output data (SPL I/O communication)
In %4 the affected component is displayed:
%4 = NCK
%4 = PLC
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
STOP D/E (settable via MD $MN_SPL_STOP_MODE) triggered on all axes with safety functionality.
Stop of the affected PROFIsafe drivers. Stopped PROFIsafe drivers of F modules of type F-DI or F-
DIO output failsafe values (0) as F user data to the SPL.
Remedy: Power OFF/ON of the control. If the error occurs again, inform the service department.
