If a DP slave cannot be identified in the loaded configuration, the following
alarm is displayed when the NCK runs-up:
•
Alarm: 27225 "PROFIsafe: Slave DP address Configuration error error"
The following error states are detected when the NCK runs-up and the
appropriate alarms are displayed:
- The DP master has not run-up or has not transferred a
configuration to the NCK
1)
- PROFIsafe communications are not possible due to differing DP
interface versions of NCK and PLC
2)
- An error has been detected while evaluating an F module
configuration:
3)
- 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"
The following error states are detected during the NCK runtime and the
appropriate alarms are displayed:
- A new configuration was downloaded into the DP master during
operation
1)
- Communications error between the F master and an F module
2)
-
Communications error between the DP master and DP slave in
which the F module is inserted
3)
- Communications error between NCK and PLC
4)
- An F module has signaled a channel error
5)
- General error message of an F module
6)
- The PROFIsafe communications cycle time is exceeded
7)
• 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"
• 4) Alarm: 27253 "PROFIsafe: Communications error F master
components
components, error error code"
• 5) Alarm: 27254 "PROFIsafe: F module F target address, Error in channel
Channel" system variable
• 6) Alarm: 27255 "PROFIsafe: F module F target address,
General Error
• 7) Alarm: 27256 "PROFIsafe: Actual cycle time Cycle time [ms] >
Parameterized cycle time"
Configuring error
Run-up error
Runtime error
