Abstract: Flexibility of constructing redundant control system is one of the main features of Foundation

Fielbus(FF) . Based on protocol of FF, levels of component redundancy are discussed in detail, and a instance of FF control system with redundancy is analogized. The analysis indicates that FF is flexible to configure redundant

system, which playes important role to completely improve reliability of control system.

Keywords: Fieldbus, FF, Reliability. redundancy
