SCADA System for Process Data Exchange in Master Slave RF and Iot Network

In every aspect of our lives, we can observe how automation plays a facilitating role in the performance of responsibilities of a comprehensive rank. Thanks to the development of electronics, today's process measurement systems enable the measurement values of process quantities to be visualized on display, sent remotely, and stored in a file, compatible with future user processing. In this paper are represented results of the development, design and practical implementation of the SCADA system, which enables data exchange between SCADA screen, MASTER and SLAVE stations. The MASTER station is installed in one industrial plant and the SLAVE is installed in another plant. The SCADA monitoring system is built into the MASTER station. The SLAVE station is connected by RF (radio frequency connection) to the MASTER station. In the MASTER and SLAVE station two microcomputers units, as well as appropriate RF modules, are installed. The microcomputer in the MASTER station is serially connected to the IoT microcomputer, for the transfer of measurement data in the Internet network. The solution provides visualization, data log file, and transfer to the IoT network of process data from the two industrial plants.
