Abstract :
Digital communication networks have become a core technology in advanced building automation systems. BACnet (building automation and control networks) is a standard data communication protocol designed specifically for building automation and control systems. BACnet adopts master-slave/token-passing (MS/TP) protocol as one of its field level networks. In this study, we introduce a method of implementing bandwidth allocation scheme in the MS/TP protocol. The bandwidth allocation scheme improves the capability of real-time communication of the original MS/TP protocol. The bandwidth allocation scheme introduced in this paper can be easily implemented in the existing MS/TP protocol with a slight modification. In this study, we actually developed the hardware and firmware of MS/TP module in which bandwidth allocation scheme is implemented.
