Hardware Configuration

Currently, configuring S7-400H system as shown in N1.png . After compilation, there is error mentioning "At least one module must be plugged into the DP slave with Profibus Address 99 in the DP Master system 2". System is communicating with ABB drive by Profibus DP Adapter Module RPBA-01. How do eliminate this error?

Hi,

Have you considered to use a Y link?

See How is the Y link structured?

At least One I/O card should be put in DP slave 99.

Hi, 

Do you have PPO card installed in the Drive interface? See the manual on the page 19-21.  

Anyways think about the Y link!!
