This paper proposes a new designing method for increasing foundation fieldbus network reliability. This method is based of inner rings providing. Device distribution structure in field of foundation fieldbus network is like to leaf structure as a natural structure. Leaves that have inner rings show more reliability than leaves with radius structure. In this paper a model with inner rings in field has been provided and this inner rings lead to increasing network reliability. We use of this method in some applied control loops of shazand Imam Khomeini oil Refinery Company in Arak in Iran. The results are very promising.
