LittleJohn Posts: 23 Rating: (1)	Hello everybody I've always used profibus so far, so I'm not too familiar with ethernet and I'd like some tips on networking of 4 cpu315: I have 4 machines and I need some data to be exchanged among them every 10ms , I think to use cpu 315 2pn/dp. Do you think they are suitable? Can I use Put and Get functions? Which protocol should I set? Can I also connect a supervisor pc? Which switch can I use? Thanks a lot

Thanks a lot Hello LittleJohn, In the following links you can find informations about networking CPU in Ethernet. Communication with SIMATIC S7 S7 Connections between CPU's with Built in Ethernet Port How do you program communication blocks FB12 "BSEND" and FB13 "BRCV" for data exchange on the S7-300? And below you can find a very good thread answered byour colleague and Platin Expert Wizard: /tf/WW/en/Posts/38483 Best regards.
