DP Connection
Shown in the following is the DP connection between a DP master (S5-115U
with IM 308-C) and a DP slave (S5-90U with CP 541).
The DP master sends five data words to the DP slave. The DP master re-
ceives two data words from the DP slave. The data are made available and
processed in flag words in the S5-90U.
The configuration for the DP connection is represented in Figure H-2.

Figure H-2 Configuration of a DP Connection
In this example, we assume that you configure the IM 308-C with
COM ET 200 Windows and that the type file is available (see Appendix F).
The configuration of the DP connection is subject to the following condi-
tions:
The IM 308-C has station number 1 and reserves pages 0 to 15.
The user-defined bus profile will be used.
A transmission rate of 500 Kbps is set.
The S5-115U with CP 944 serves as the host.
The inputs and outputs will be addressed linearly.
The CP 541 has station number 3.
The IM 308-C receives two data words from the CP 541.
The IM 308-C sends five data words to the CP 541.
Address P000 is assigned in the DP master as the start address for the in-
puts and for the outputs.
