Abstract: SCADA systems are widely spread in automation, monitoring and control systems for industrial processes. These systems are used to develop the factories of the future. Currently, the most SCADA systems allow data sharing only within a local network. With the development of the Internet of Things concept, it was started to be used in the systems for the factories of the future. One of the most powerful middleware systems used for the Internet of Things is these based on the DDS middleware systems. In this paper, it is presented the integration of the DDS middleware based systems within an SCADA system in order to enable the Internet of Things concept.

Keywords: Internet of Things, middleware, data distribution service, SCADA.
