PROFIBUS with STEP 7 V13
44 Function Manual, 12/2014, A5E03775446-AC
To assign DP slaves to a DP master, follow these steps:
1. On the DP slave, use the left mouse button to click on the "Not assigned" link. The
"Select DP master" menu opens.
2. Select the DP master in the menu to which you want to assign the DP slave.
A subnet with a DP system is created on the CPU. The CPU is now the
PROFIBUS DP master. The DP slave is assigned to the DP master.
3. Repeat steps 1 and 2 for all other DP slaves that you want to assign to the DP master.

● The selection of the CPU shows the DP communication of the CPU.
● The selection of the station shows the communication of the entire station.
● The selection of the interface shows the DP communication of the interface.
