Structure Of Station Status 1 (Byte 0); Station Statuses 1 To 3 - Siemens SIMATIC ET 200S Manual

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
0 1: The DP slave cannot be addressed
by the DP master.
1 1: The DP slave is not yet ready to
exchange data.
2 1: The configuration data sent by the
DP master to the DP slave does not
correspond to the setup of the DP
slave.
3 1: External diagnosis available.
(Group diagnosis indication)
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 from the DP slave.
6 1: The DP slave type does not
correspond to the software configu-
ration.
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).

Commissioning and Diagnostics
Cause/remedy
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?
•
Wait while the DP slave starts up.
•
Correct station type or correct setup of the
•
DP slave entered in the configuration
software?
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.
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.
