Station status - definition
The station status provides an overview of the state of a DP slave.
Station status 1
Table 12-3: Configuration of station status 1 (byte 0)
Bit Meaning Cause/corrective measures
0 The DP slave cannot be
addressed by the DP master.
Check the following:
• Is the correct PROFIBUS address set on
the DP slave?
• Is the bus connection plug plugged in?
• Is the DP slave connected to the power
supply?
• Is the RS-485 repeater configured
correctly?
1 The DP slave is not yet ready for the
data transfer.
The DP slave is just starting up.
Wait until the startup is completed.
2 The configuration data sent from the
DP master to the DP slave does not
correspond to the configuration of
the DP slave.
Check whether the correct station type and
the correct configuration of the DP slave
has been entered in the configuration
software.
3 External diagnostics is available
(general diagnostics display)
Evaluate the identification-related
diagnostics, the status information and/or
the channel-related diagnostics.
Bit 3 is reset as soon as all errors are
rectified. The bit is reset if there is a new
diagnostic message in the bytes of the
above-mentioned diagnostic functions.
4 The required function is not
supported by the DP slave
Check the configuration.
5 The DP master cannot interpret the
response of the DP slave.
Check the bus configuration.
6 The DP slave type does not
correspond to the software
configuration.
Enter the correct station type in the
configuration software.
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).
Bit is always 1 when you are accessing the
DP slave from the programming device or
from another DP master (for example).
The PROFIBUS address of the DP master
which parameterized the DP slave is in the
"Master PROFIBUS address" diagnostic
byte.
