for the PROFIsafe cycle time defined by the MD
$MN_PROFISAFE_IPO_TIME_RATIO.
%2 = CRC2_Len: Incorrect length of the telegram CRC.
%2 = F_Data_Len: The incorrect telegram length has been defined for the
stated module.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
Remedy %2 = CRC1: General PLC reset, reload the S7 F configuration.
%2 = F_WD_Timeout: Reparameterize the PROFIsafe cycle time or F
monitoring time.
%2 = CRC2_Len: General PLC reset, reload the S7 F configuration.
%2 = F_Data_Len: General PLC reset, reload the S7 F configuration.
Program continuation Power-down the control and power-up again.
27250 PROFIsafe: Configuration in DP-M changed;
Error code %1 – %2
Parameter %1 = NCK project Number
%2 = Current PLC project number
Explanation The DP master shows a modified S7 PROFIBUS configuration. Error-free
operation can no longer be guaranteed.
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
Communications with the F slaves is terminated.
A STOP D/E is initiated (this can be set using MD $MN_SPL_STOP_MODE)
on all of the axes with safety functionality.
Remedy Restart the PLC/NCK.
Program continuation Power-down the control and power-up again.
27251 PROFIsafe: F module %1, %2 reports error %3
Parameter %1 = PROFIsafe address
%2 = Signaling components (master/slave)
%3 = Error detection
Explanation An error has occurred in the PROFIsafe communication between the F master
and the specified F module which was detected by the signaling component
(master/slave).
The error code specifies the error type:
- %3 = TO: The parameterized communications timeout has been exceeded
- %3 = CRC: A CRC error was detected
- %3 = CN: An error was detected in the sequence (timing) of the F telegrams
- %3 = SF: F master error, NCK/PLC are no longer in synchronism
- %3 = EA: Communications error, slave sends empty telegrams
Response Mode group not ready
Channel not ready
NC start inhibit in this channel
Interface signals are set
Alarm display
NC stop for alarm
A STOP D/E is initiated (this can be set using MD $MN_SPL_STOP_MODE)
on all of the axes with safety functionality.
