SINUMERIK 840D/SIMODRIVE 611 digital SINUMERIK Safety Integrated (FBSI) - Edition 11.03
Alarm: 27225 "PROFIsafe: Slave DP address Configuration error error "
The DP master has not run-up or has not transferred a
-
configuration to the NCK
PROFIsafe communications are not possible due to differing DP
-
interface versions of NCK and PLC
An error has been detected while evaluating an F module
-
3)
configuration:
CRC error detected using F parameter
-
The F monitoring time set in the F module is too short
-
compared to the PROFIsafe clock cycle
The F telegram lengths entered in the configuration
-
cannot be processed by the NCK
1) Alarm: 27240 "PROFIsafe: DP M has not run-up, DP info: Info "
2) Alarm: 27241 "PROFIsafe: DP M version different, NCK: Version ,
PLC: Version "
3) Alarm: 27242 "PROFIsafe: F module F target address ,
Parameter incorrect"
A new configuration was downloaded into the DP master during
-
1)
operation
Communications error between the F master and an F module
-
Communications error between the DP master and DP slave in
-
which the F module is inserted
Communications error between NCK and PLC
-
An F module has signaled a channel error
-
General error message of an F module
-
The PROFIsafe communications cycle time is exceeded
-
1) Alarm: 27250 "PROFIsafe: Configuration in DP-M has been changed;
Error code Error code1 – Error code2 "
2) Alarm: 27251 "PROFIsafe: F module F target address , F components
signals error parameter "
3) Alarm: 27252 "PROFIsafe: Slave DP address , sign-of-life error"
