8.3.2 Inserting DP slaves
In principle, both PROFIBUS interfaces have the same functionality. They
merely differ in the way they can be accessed by the NC and the PLC:
S The NC only has access to the PROFIBUS interface (X101) corresponding
to slot X2.
S The PLC has access to both PROFIBUS interfaces (X101 and X102) corre-
sponding to slots X2 and X1.
Note
S PROFIBUS(1), interface (X101) corresponding to slot X2:
As the drives are connected via this interface, the PROFIBUS can only be
operated in mode ”DP master”.
S PROFIBUS(2), interface (X102) corresponding to slot X1:
The interface can be operated in modes: ”DP master” and ”DP slave”.
Please refer to the relevant SIMATIC documentation for how to connect the
PLC to the higher–level DP master as a DP slave.
