GFK-1911B Chapter 6 Diagnostics
Meaning, Cause
The DP slave is not
addressed by the DP master
The DP slave is not ready
for data exchange
The configuration data sent
from the DP master to the
DP slave does not
correspond to the
configuration of the DP
slave.
An external diagnostic is
present (group diagnostic
indicator)
The required function is not
supported by the DP slave.
The DP master cannot
interpret the reply of the DP
slave
The DP slave type does not
correspond with the
software configuration
The DP slave has been
parameterized by another
DP master (not by the DP
master that currently has
access to the DP slave)
Remedy
Is the correct Profibus address set on
the DP slave?
Is the bus connector connected?
Is there voltage to the DP slave?
Is the RS-485 repeater set correctly?
Has the DP slave been reset?
Wait, because the DP slave is starting
up
Has the correct station type or the
correct DP slave configuration been
entered in the configuration software?
Evaluate the identification-specific
diagnostics, the module status and/or
the channel-specific diagnostics. Once
all errors have been removed, bit 3 is
reset. The bit is reset when a new
diagnostic message is present in the
bytes of the above diagnostics.
Check configuration
Check bus configuration
Is the correct station type specified in the
configuration software?
Bit always has the value 1, if, for
example, you access the DP slave with
the PG or another DP master.
The Profibus address of the DP master
that parameterized the DP slave is
located in the diagnostic byte "master
Profibus address".
