DP slave cannot be addressed by DP master.
•
Is the correct DP address set on the DP
slave?
•
Is the bus connector in place?
•
Does the DP slave have power?
•
Correct configuration of the RS485
Repeater?
•
Perform a reset on the DP slave.
1
DP slave is not ready for data exchange.
•
Wait for the slave to complete start-up.
2
Configuration data sent by DP master to the DP
slave is inconsistent with slave configuration.
•
Was the software set for the correct
station type or DP slave configuration?
3
Diagnostic interrupt, generated by a RUN to
STOP transition on the CPU or by the SFB 75
Diagnostic interrupt, generated by a STOP to
RUN transition on the CPU or by the SFB 75
•
You can read the diagnostic data.
4
Function not supported; e.g. changing the DP
address at software level
•
Check configuration data.
5
This bit is always “0”.
•
-
6
DP slave type inconsistent with software
configuration.
•
Was the software set for the right station
type? (parameter assignment error)
7
DP slave was configured by a DP master other
than the master currently accessing the slave.
•
The bit is always 1 if, for example, you are
currently accessing the DP slave via PG or
a different DP master.
The configuring master's DP address is
located in the ”Master PROFIBUS address”
diagnostics byte.

The DP slave requires new parameters and configuration.
1
A diagnostic message was received. The DP slave cannot resume operation until the error
has been cleared (static diagnostic message).
2
This bit is always ”1” if a DP slave exists with this DP address.
3
The watchdog monitor is enabled on this DP slave.
4
DP slave has received control command "FREEZE".
5
DP slave has received control command "SYNC".
6
This bit is always "0".
7
DP slave is disabled, that is, it has been excluded from cyclic processing.
