2.1 PROFIBUS communication
Station status - definition
The station status provides an overview of the state of a DP slave.
Station status 1
Table 2- 3 Structure of station status 1 (byte 0)
Bit Meaning
0 The DP master cannot address the DP slave.
1 The DP slave is not yet ready for the data transfer.
2 The configuration data transferred from the DP master
to the DP slave does not match the DP slave
configuration.
3 External diagnostics data exists
(group diagnostics indication).
4 The function you requested is not supported by the DP
slave.
5 The DP master cannot interpret the response from the
DP slave.
6 The DP slave type does not match the software
configuration.
7 The DP slave has been parameterized by another DP
master (not by the DP master which has access to the
DP slave at the moment).

Cause / corrective measure
Check the following:
Is the correct PROFIBUS address set on the DP
•
slave?
Is the bus connection plug connected?
•
Is the DP slave connected to the power supply?
•
Is the RS485 repeater correctly configured?
•
The DP slave is still starting up.
Wait until the startup is completed.
Check that the correct station type and the correct DP
slave configuration have been entered in the configuring
software.
Evaluate the identifier-related diagnostics, the status
information and / or the channel-related diagnostics.
Bit 3 is reset as soon as all faults have been rectified.
The bit will be set again when there is a new diagnostics
message in the bytes of the aforementioned diagnostics.
Check the configuration.
Check the bus configuration.
Enter the correct station type in the configuring software.
The bit is always 1, for example, if you access the DP
slave with the PG or another DP master. The "Master
PROFIBUS address" diagnostic byte contains the
PROFIBUS address of the DP master that assigned
parameters to the DP slave.
