PROFIBUS DP Communication Module
8.9.4 Station Status 1 to 3
Definition
Station status 1
Bit
0 1: The DP slave cannot be addressed by the
DP master.
1 1: The DP slave is not yet ready for data
exchange.
2 1: The configuration data sent to the DP
slave by the DP master do not match the
structure of the DP slave.
3 1: There is an external diagnosis. (Group
diagnosis display)
4 1: The requested function is not supported
by the DP slave (e.g. changing of the
station address via software).
5 1: The DP master cannot interpret the reply
from 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
accessing the DP slave at the moment).
Table 8-10: Station status 1 structure (byte 0)
8-28
Station status 1 to 3 gives an overview of the status of a
DP slave.
Meaning Cause/Remedy
• Has the station address been set correctly at the DP slave?
• Is the bus connector connected?
• Is voltage applied at the DP slave?
• Is the RS 485 repeater set correctly?
• Has a reset been carried out on the DP slave?
• Wait, since the DP slave is just starting up.
• Has the correct station type or the correct structure for the
DP slave been entered into the configuration software?
• Analyze the code-based diagnosis, the module status and /
or the channel-related diagnosis. As soon as all errors have
been remedied, bit 3 is reset. The bit is set again when a
new diagnosis message is available in the bytes of the
above mentioned diagnoses.
• Check the configuration.
• Check the bus design.
• Has the correct station type been entered into the
configuration software?
• Bit is always 1 when you are accessing the DP slave with
the PD or another DP master, for example.
The station address of the DP master which carried out the
parameterization of the DP slave can be found in the
"Master PROFIBUS Address" diagnostic byte.
