The following configuration steps are required to be able to access the secondary CPU412 control with the SIMATIC STEP 7 programming software. For SINUMERIK, SINAMICS, or SIMOTION, you can apply similar steps. For using ibaPDA, these configuration steps are not required.

1. Add a PG/PC station and configure it.

   
   

   

   
   

2. Assign an interface (network card).

   
   

   

   
   

   Result:

   
   

   

   
   

   Now, the connection line from PG/PC to the network has to be marked in yellow.

   In the following figure, the communication path is shown using arrows (these are not displayed in SIMATIC NetPro).

   
   

   

   
   

3. Finally, load all hardware configurations and connection data from NetPro.
