Part number:

Description
This entry includes sample programs and documentation for using the PROFIBUS DP (Distributed I/O or Periphery) for data communication between SIMATIC S5 modules and SIMATIC S7 modules.

Using the PROFIBUS DP protocol the data is transferred cyclically between DP master and DP slave. This means

The DP master reads data from the input area of the DP slave.
The DP master writes data to the output area of the DP master.
