7.6.1 Station status 1 to 3
Definition
Station status 1 to 3 provides an overview of the status of a DP slave.
Station status 1
Table 7-8 Structure of station status 1 (byte 0)
Bit Description Remedy
0 1: DP slave cannot be addressed by
DP master.
Is the correct DP address configured for the
DP slave?
Is the bus connector inserted?
Does the DP slave have power?
Is the RS 485 repeater correctly set?
Execute a reset on the DP slave.
1 1: DP slave is not ready for data
interchange.
Wait; the DP slave is still doing its run-up.
2 1: The configuration data which the
DP master sent to the DP slave do
not correspond with the DP slave’s
actual configuration.
Correct station type or correct configuration
of the DP slave entered in the configuration
software?
3 1: Diagnostic interrupt, generated by
RUN-STOP transition of the CPU or
by the SFB 75
0: Diagnostic interrupt, generated by
STOP-RUN transition of the CPU or
by the SFB 75
You can read out the diagnostic data.
4 1: Function is not supported, for
instance changing the DP address
at the software level.
Check the configuration data.
5 0: This bit is always ”0”. –
6 1: DP slave type does not correspond
to the software configuration.
Was the configuration software set for the
right station type? (parameter assignment
error)
7 1: DP slave was parameterized by a
different DP master to the one that
currently has access to it.
Bit is always ”1” when, for instance, you are
currently accessing the DP slave via the PD
or a different DP master.
The DP address of the master that
parameterized the slave is located in the
”Master PROFIBUS address” diagnostic
byte.
