The Proportional Integral Derivative (PID) controller has been the most widely used controller in the industry for decades due to its various advantages, one of the most important being the cost/benefit ratio it can provide, in addition to the fact that it is a methodology that has been adapted to new technologies over the years. Currently, with the rise of industry 4.0, it is imperative to provide affordable educational tools that allow students to delve into these technologies. Implementation of a PID control in an OPC UA server allows to eliminate proprietary barriers and streamline monitoring and controlling in production processes usisng it. This paper presents the methodology for implementing a didactic PID control with an OPC UA server mounted on a Raspberry Pi, which gives the opportunity to introduce young university students to an industry 4.0 environment so that in their professional future they can achieve rapid adaptation to the productive sector.

Keywords : PID; OPC UA; Raspberry Pi; Arduino; UA Expert; Visual Studio.
