Station statuses 1 to 3

Definition
Station statuses 1 to 3 provide an overview of the status of a DP slave.
Structure of station status 1 (byte 0)
Table 3- 3 Structure of station status 1 (byte 0)
Bit
0 1: The DP slave cannot be accessed by the DP
master.
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 do not match the slave
configuration.
3 1: External diagnostic information exists. (Group
diagnostic display)
4 1: The required function is not supported by the DP
slave (for example, changing the PROFIBUS
address by means of software).
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: Parameters have been assigned to the DP slave
by a different DP master (not the one that currently
has access to the DP slave).

Meaning Cause/remedy
Is the correct PROFIBUS address set on the DP slave?
•
Is the bus connector plugged in?
•
Voltages on DP slave?
•
RS 485 repeater set correctly?
•
DP slave reset?
•
Wait, the DP slave is currently starting up.
•
Correct station type or correct configuration of the DP
•
slave entered in the configuration software?
Evaluate the channel-related diagnostic information, the
•
module status and/or the channel-related diagnostic
information. As soon as all errors have been eliminated,
bit 3 will be reset. The bit will be set again when there is a
new diagnostic message in the bytes of the
aforementioned diagnostics.
Check the configuration.
•
Check the bus configuration.
•
Correct station type entered in the configuration software?
•
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.
