SCADA system design: A proposal for optimizing a production line

By addressing a series of authorization requirements for a production line, this research paper deals with the implementation of a SCADA system that provides information of the production line status in real time, which help in the decision-making during and after the process. The cost and difficulty of use, installation and maintenance are some of the common problems in the SCADA systems, the proposed solution considers these problems by providing a low cost platform and easy to operate with the possibility to implement a basic system with a microcontroller card or the integration of subsystems with high-end devices, integrating various hardware technologies, adding flexibility and scalability to system features. The solution includes a web app, a data warehouse, as well as real time communication techniques between the different levels. It is proposed to use WebSocket technology as a means of communication between slaves and masters levels. Another important feature of the proposal is to manage the logistics in a master server to coordinate each node of the process, which can be reconfigurable and controlled automatically with specified parameters or manually. The system counts with a monitoring option and a remote control for the production line, making information accessible from anywhere and on any device.
