Station Status 1, 2 and 3
Station status 1, 2 and 3 provide an overview of the status of the slave.
Station Status 1
Bit Description Cause
0 - Station nonexistent The master cannot be
addressed by the master
•
Correct node address set on the
adapter?
•
Bus connector connected?
•
Bus cable pin configuration
correct (Pin 3 to 3 and pin 8 to 8)?
•
Power to the slave switched on?
•
Is the RS485 repeater set

1 - Station not ready Adapter not yet ready for
data exchange Wait for the adapter to start up.
2 - Configuration fault Configuration data sent by
the master to the adapter
does not match the
backplane configuration. Do the modules installed in the
backplane match the modules entered
in the master configuration?
3 - Extended diagnostic Diagnostics available for the
master Evaluate the module-related and/or
channel-related diagnostics.
This bit is cleared (0) when there are no
diagnostic messages available.
4 - Function not supported The requested function is
not supported by the module Trying to set PROFIBUS address over
the network?
5 - Invalid slave response The master has received an
invalid response Check the bus setup.
6 - Parameter fault Parameters sent by the
master are containing
wrong or insufficient data. Do the modules installed in the
backplane match the modules entered
in the master configuration?
7 - Master lock The adapter has already
been parameterized by
another master and is
locked in its access. Check if another master is present on
the network, and delete its
assignments to the adapter or remove
the other assigned master from the
network to get the communication with
the adapter run.
