Implementation of Communication Protocol BACnet in AC500

Abstract

This work deals with the design and implementation of a BMS system communication network for data centers. BACnet and OPC Classic communication protocols were used for the implementation of the network. The aim of the work was to create an implementation-efficient and modular solution that can be applied in the future for the implementation of more complex solutions of BMS systems. The theoretical part contains a technical overview of the application area and an analysis of the use of BACnet protocol in industrial control systems. The result of the practical part is a communication system based on BACnet protocol, which is used to exchange data between two AC500 PLCs produced by ABB com-pany. The communication system also includes a distributed control system 800xA manufactured by ABB, which has the function of remote monitoring and control, archiving of measured data, and alarm diagnostics of the monitored systems.
