27250 PROFIsafe: configuration in DP M changed; error code %1 - %2
Parameters: %1 = NCK project number
%2 = Current PLC project number
Definitions: The DP master shows a modified S7 PROFIBUS configuration. Error-free operation can no longer be
guaranteed.
Reaction: Mode group not ready.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Communication with F slaves is finished.
A STOP D/E (settable via MD $MN_SPL_STOP_MODE) is triggered on all axes with safety
functionality.
Remedy: Restart the PLC/NCK.
Program Switch control OFF - ON.
Continuation:
27251 PROFIsafe: F module %1, %2 reports error %3
Parameters: %1 = PROFIsafe address
%2 = Reporting component (master/slave)
%3 = Error code
Definitions: An error occurred in the PROFIsafe communication between the F master and the specified F module
which was detected by the component (master/slave) shown in parameter %2.
The error code specifies the error type:
- %3 = TO: The parameterized communication timeout was exceeded
- %3 = CRC: A CRC error was detected
- %3 = CN: An error in the time sequence of the F messages was detected
- %3 = SF: F master error, NCK/PLC are no longer synchronous
- %3 = EA: Communication error, slave sends empty messages
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 the DP wiring. Restart F slave modules. Restart the NCK/PLC.
Program Clear alarm with the RESET key. Restart part program
Continuation:
27252 PROFIsafe: Slave %1, sign-of-life error
Parameters: %1 = DP slave address
Definitions: The specified DP slave no longer communicates with the master.
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 the DP wiring. Restart F slave modules. Restart the NCK/PLC.
Program Clear alarm with the RESET key. Restart part program
