Remote Control and Monitoring of an Academic Station Using a Low-Cost Embedded Device

The work of this paper focuses on an Automatic System, which allows the control of an educational process control station, and its remote monitoring. Its application is of an academic nature; therefore, it was implemented in a Festo Station. Due to the limitations of this equipment, communication can be achieved through a Raspberry Pi 2, which can be accessed from a computer through a server. The connection was implemented using three different methods that connect the board and the PLC that is attached in the process, to evaluate which method performs better. To carry out the control actions of the process variables, an interface that can be accessed with a stable Internet connection has been developed. In addition to this, the option of monitoring time is offered through the use of a modular camera. The validation of the operation of this proposal is made with the use of simulators, as well as its experimental implementation.
