Meaning
1: The DP slave cannot be
addressed by the DP master.
1: DP slave is not ready for the
data exchange.
1: The configuration data sent to
the DP slave by the DP master
does not match the actual
configuration of the DP slave.
1: External diagnostics information
is pending.
(Group diagnostics indication)
1: The required function is not
supported by the DP slave (for
example, changing the
PROFIBUS address by means of
software).
1: The DP master cannot interpret
the response of the DP slave.
1: The DP slave type does not
match the software configuration.
1: DP slave was configured by a
different DP master (not by the DP
master that currently has access
to the DP slave).
Cause/remedy
Is the correct PROFIBUS address set on the DP
•
slave?
Is the bus connector in place?
•
Does the DP slave have power?
•
Correct configuration of the RS485 rpeater?
•
Has the DP slave been reset?
•
Wait, the DP slave is currently starting up.
•
Has the correct station type or the correct DP slave
•
configuration been entered in the configuration
software?
Evaluate the ID-specific diagnostics information, the
•
module status, and/or the channel-specific diagnostics
information. As soon as all errors are remedied the bit
3 is reset. The bit will be set again when there is a new
diagnostics message in the bytes of the
aforementioned diagnostics.
Check configuration data.
•
Check the bus installation.
•
Has the correct station type been entered in the
•
configuration software?
The bit is always 1 if, for example, you are currently
•
accessing the DP slave via PG or a different DP
master. The "master PROFIBUS address" diagnostic
byte contains the PROFIBUS address of the DP
master that assigned parameters to the DP slave.
