6.1.6.3 Station statuses 1 to 3
Definition
Station statuses 1 to 3 provide an overview of the status of a DP slave.
Station status 1
Table 6-8 Structure of station status 1 (byte 0)
Bit Meaning Cause/remedy
0 1: The DP slave cannot be addressed
by the DP master.
•
Correct PROFIBUS address set on the
DP slave
•
Bus connector connected?
•
Voltage at DP slave?
•
RS 485 repeater set correctly?
•
Reset carried out on DP slave?
1 1: The DP slave is not yet ready to
exchange data.
•
W ait while the DP slave starts up.
2 1: The configuration data sent by the
DP master to the DP slave does not
correspond to the setup of the DP
slave.
•
Correct station type or correct setup of the
DP slave entered in the configuration
software?
3 1: External diagnosis available.
(Group diagnosis indication)
•
Evaluate the module diagnosis, the module
status and/or the channel-specific
diagnosis. Bit 3 is reset as soon as all the
faults have been rectified. The bit is reset
when there is a new diagnostic message in
the bytes of the diagnostics mentioned
above.
4 1: The required function is not
supported by the DP slave (for
example, changing the PROFIBUS
address by means of software).
•
Check the configuration.
5 1: The DP master cannot interpret the
response from the DP slave.
•
Check the bus configuration.
6 1: The DP slave type does not
correspond to the software configu-
ration.
•
Correct station type entered in the
configuration software?
7 1: Parameters have been assigned to
the DP slave by a different DP
master (not the one that currently
has access to the DP slave).
•
The bit is always 1, for example, if you
access the DP slave with the programming
device or another DP master.
The PROFIBUS address of the DP master
that assigned parameters to the DP slave is
located in the ”master PROFIBUS address”
diagnostic byte.
