DP Slaves Connectable to a Y Link
C-2
DP/PA Link and Y Link Bus Couplings
A5E00193841-011
Restrictions
In the underlying DP master system, operator panels and text displays can only
be operated as DP slaves and not as active bus nodes.
Slaves in the DPV1 mode cannot be operated in the underlying DP master
system if the Y link is in DPV0 mode (DP master in “S7-compatible” mode).
Configuration of S7-300/S7-400 stations as I slaves
The CPU for an S7-300 or S7-400 station cannot be used out of the “preconfigured
stations” catalog directory but must be integrated via the device master file.
When configuring the S7-300/S7-400 station, a “dummy” DP system must be
created that has the same bus settings (transmission rates, etc.) as the underlying
DP master system of the Y link but not the same bus name. The station number of
the S7-300/S7-400 must coincide with the slave address on the Y link.
Examples of usable DP slaves
The table below shows a selection of field devices that can be defined via the
device master file as DP slaves. It also presents all of the S7-CPUs that can be
used as I slaves with various I/O ranges.
