Diagnostics Addresses in Connection with DP Slave Functionality
You assign diagnostics addresses for the PROFIBUS DP in the CPU 41x. Ensure
during configuration that DP diagnostics addresses are assigned once to the DP
master and once to the DP slave.
You specify two diagnostics addresses during configuration:
PROFIBUS
DP-SlaveS7-CPU as DP master
Diagnostics address
Diagnostics address
During the configuration of the DP
master, you specify (in the associated
project of the DP master) a diagnostics
address for the DP slave. In the
following, this diagnostics address is
described as being assigned to the DP
master.
During the configuration of the DP slave,
you also specify (in the associated
project of the DP slave) a diagnostics
address that is assigned to the DP slave.
In the following, this diagnostics address
is described as being assigned to the
DP slave.
By means of this diagnostics address
the DP master receives information on
the status of the DP slave or a bus
interruption (see also Table 4-8).
By means of this diagnostics address
the DP slave receives information on the
status of the DP master or a bus
interruption.
