Abstract :
The use of network-based control has become widespread in building automation systems. BACnet(building automation and control networks) adopts master-slave/ token-passing(MS/TP) protocol as one of its local area networks. This study introduces a bandwidth allocation scheme in the MS/IP protocol. The bandwidth allocation scheme improves the capability of real-time communication of the original MSA IT protocol. The bandwidth allocation scheme introduced in this paper can he easily implemented in the existing MS/TP protocol with a slight modification. In this study, we examined the validity of bandwidth allocation scheme using simulation models. The results from the simulation experiment show that the proposed scheme satisfies the requirements of real-time communication.
