This primer on fieldbus concentrates on the two basic fieldbuses used in process control: Profibus PA and Foundation Fieldbus™ H1. It covers how fieldbus works, shows how to connect instruments, and explains why, in most cases, you can't connect all 32 instruments on a single fieldbus segment, as all the advertising claims.
