I/O Interface Via Profinet Io; Example Of A Profibus Dp Network - Siemens SIMATIC S7-400 Configuration And Use Manual

Interfaces, Networks and Data Communication for the S7-400
Example of a PROFIBUS DP Configuration
Figure 5-5 shows an example of a PROFIBUS DP configuration with devices from
the SIMATIC S7, SIMATIC S5 and ET 200 series. The S7-400 is the DP master in
this configuration, all other devices are DP slaves.
