Devicenet,profibus

I Am Trying To Gather Information Regarding Devicenet I.e How It Works ,how To Configure,which Model Has To Be Used,how To Establish Several Links Between N No Of Controllers Using Devicenet And Few Things More.
Similarly For Profibus

Can Any One Guide Me Where I Can Get This Information. It Would Be Very Suitable If I Could Find Pdf Files Or Documentated Things Of All This Or His/her Practical Experiences Shared.

Thanks & Regards.
