Abstract: Foundation Fieldbus data link layer protocol was analyzed. The software module based on Nucleus Plus was developed. The self copyrighted communication stack was implemented and passed the conformance test in the laboratory by using Conformance Test Bed. And this protocol software supported the basic device and master device of Foundation Fieldbus.
