Station states 1 to 3

Definition
Station states 1 to 3 provide an overview of the status of a DP slave.
Structure of station status 1 (byte 0)
Bit Meaning
0 1: The DP master cannot address the DP slave.
1 1: The DP slave is not yet ready to exchange data.
2 1: The configuration data transferred from the DP
master to the DP slave does not match the DP
slave configuration.
3 1: External diagnostic information exists.
(group diagnosis display)
4 1: The DP slave does not support the requested
function (modification of the PROFIBUS address in
the software, for example).
5 1: The DP master cannot interpret the response of
the DP slave.
6 1: The DP slave type does not match the software
configuration.
7 1: The DP slave was parameterized by a different
DP master (not by the DP master which currently
has access to the DP slave).

Cause/remedy
Check the PROFIBUS address of the DP slave.
•
Check the PROFIBUS DP connection.
•
Check the power supply to the DP slave.
•
Check the settings of the RS 485 repeater.
•
Check whether the DP slave was reset.
•
Wait, the DP slave is currently starting up.
•
Verify the station type and configuration of the DP slave in
•
the configuring software.
Evaluate the ID-specific and/or channel-specific diagnostic
•
information, and the module status. Bit 3 is reset after all
errors are cleared. The bit will be set again if a new
diagnostic message is output in the bytes of the
diagnostics functions mentioned above.
Check the configuration.
•
Check the bus configuration.
•
Compare the preset to the actual configuration
•
The bit is always 1 if, for example, you are currently
•
accessing the DP slave from the PG or a different DP
master.
The PROFIBUS address of the DP master which has
•
parameterized the DP slave is in the "Master PROFIBUS
address" diagnostics byte.
