"Adaptación de la tecnología estándar de comunicación en el campo del control y supervisión de procesos industriales (OPC), en un prototipo de sistema SCADA basado en la plataforma Ignition y controladores lógicos programables"

Abstract

The implementation of an OPC communication architecture, allows to integrate diverse independent technologies of the manufacturer, offering a better management in the control and monitory of an industrial process. The existence of proprietary systems dependent of hardware and skilled software, require of costly investments and of problems of interoperability in front of a deficient adaptation. In this, the protocol OPC presents a firm solution, reliable and flexible, deleting these impositions endowments that the OPC Foundation compact in his versions of OPC classical and OPC UA. This graduation work shows a prototype of system OPC SCADA designed in the platform Ignition, which controls and monitor from a local network the micro climate of a greenhouse scale model. By means of basic control techniques, it is possible to regulate the climatic conditions of humidity, temperature and quantity of water. To do it, it is employed OPC servers with different types of technologies (PLC, Arduino and Raspberry Pi) that manage several processes and that are executed from different platforms. In conclusion, the prototype proposed, constitutes an interesting subject to explore new alternatives, by evaluating embed devices so that they can be used as profitable and sustainable tools in the industry, allowing the adequacy of this technology with a very low cost of investment.
