One version of the S5-95U has an integral interface for connecting the
S5-95U as a DP master to the SINEC L2 DP.
The DP master interface is integrated in the S5-95U:

The S5-95U with DP master interface offers:
256 bytes of address space (128 bytes inputs, 128 bytes outputs; linear
addressing only).
baud rates from 9.6 kbaud to 1.5 Mbaud.
connection of max. 16 DP slaves.
The S5-95U with DP master interface does not offer:
support for DP slaves that cannot be limited to a telegram length of 32
bytes (e. g. DP/AS-I Link cannot be used because parameterization tele-
gram is too long). The S5-95U processes a maximum of 32 inputs and 32
outputs per DP slave.
use as a shared-input master.
selection of an error messaging mode.
The S5-95U with DP–master interface is described in detail in Chapter 4.
Information applicable to the S5-95U with DP master interface and to all
other versions of the S5-95U is to be found in the system manual
S5-90U/S5-95U Programmable Controller. See Appendix F for the order
number of this manual.
