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:

,
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)
