Sistema de control y adquisición de señales con hardware y software libre y su incidencia en la industria.

Abstract

The objective of this research was the implementation of a system of control and signals acquisition with free hardware and software to determine its applicability in the industry. The executed project consisted of carrying out an analysis of the behavior of an automatized hydraulic press using proprietary and free technology; whit this, it is possible to demonstrate that the system of hardware and software allows companies to have leading-edge technology in their production plants, which adapts its necessities and evolving according to future requirements due to the implementation cost is low. The automatized system consisted of analogic and industrial digital sensors and actuators using on one side the proprietary system controlled by a Programmable Logical Controller (PLC S7-1200) of Siemens and user interface based on LabVIEW through an OPC server; on the other side free system controlled by a Programmable Logical Controlled (PLC M-DUINO) based on Arduino, monitored through a Web Service System hosted in a LAMP server. It is determined that the free system provides better performances due to it does not require special libraries for compatibility of sensors and actuators of differente brands and its cost of implementation on ten times less than the proprietary. It is recommended to use correctly the Arduino Platform and the LAMP server.
