Low-Cost Supervisory Control and Data Acquisition Systems

This paper presents the development of low-cost industrial software focused on industries with limited investment capacity. This propose aims to promote SCADA System integration in process of the small and mid-sized industries. In this regard, the proposed software includes both a Modbus communication application and a HMI based on a web server application for SCADA System implementation. Finally, performance of developed software is tested through the emulation of a practical process.
