7 PROFIBUS DP Communication
7.3 SIMATIC S7 project
After DP master has been configured, 840Di Rack with PROFIBUS DP is now
displayed in the Station window.
You can use the axis start-up tool SimoCom U to start up all DP slaves 611U
connected to PROFIBUS from a SINUMERIK 840Di. To allow this, the PLC
must route SimoCom U to PROFIBUS. This requires that the MPI interface of
the PLC is networked.
To do so, open the Properties dialog box by double-clicking on the PLC in 840Di
The following settings are made in the dialog box:
Data transfer rate.
Dialog: Properties of PLC315-2DP M/S 2AF03
Dialog: Properties – MPI Interface PLC315-2DP M/S 2AF03
Address: 2 (see Note)
Dialog: Properties – MPI
Tab "Network Settings"
Data transfer rate: 1.5 Mbps
With SINUMERIK 840Di, the MPI address of the PLC must always be set to "2".
