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
consideration when making the setting.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27299 PROFIsafe: Diagnostics %1 %2 %3 %4
Parameters: %1 = Error code 1
%2 = Error code 2
%3 = Error code 3
%4 = Error code 4
Definitions: Internal error in the NCK PROFIsafe implementation.
Reaction: Alarm display.

Continuation:
27900 PROFIBUS DP: SI fault on axis %1, code %2, value %3, time %4.
Parameters: %1 = Axis number
%2 = Fault code of the drive (p9747).
%3 = Fault value of the drive (p9749)
%4 = Fault time of drive (p9748).
Definitions: Error in a SINAMICS drive.
Reaction: Alarm display.
Remedy: See drive documentation for fault codes/fault values.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:

%3 = Fault value of the drive (p9749)
%4 = Fault time of drive (p9748).
Definitions: Error in a SINAMICS drive.
Reaction: Alarm display.
Remedy: See drive documentation for fault codes/fault values.
