Profinet connection [MOVED]

Ercan

Hi everybody.

I have 2 problems. And I hope you can have 2 answers for me. 

1- I have 3 ABB IRC5 robots. and these robots has profinet fieldbus adapter slave. PLC will be master. My friend made a configuration for these robots. Then I just changed Input/ouput bytes. then they work. But just one robot cant connect to profinet line. Everythng is same in I/O CFG file. Do you have any solitions for me?

2- I want to connect all robots with ethernet switch. All robots connect to ethernet swtich with profinet fieldbus adapter. Is that possible?

Thanks for all
