Parameter assignment/addressing
3.1 Assigning the DP slave to a DP master
Procedure
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.
Result: 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.
