Type: article
Abstract: At present, the application of the programmable logic controller (PLC) in automation of industrial processes continues to have enormous opportunities due to its robustness and ease of programming control algorithms, it is also true that there is a shortage of teaching material in higher level schools in this area, usually because of the cost.This work describes the construction and control of a tank or experimental physical model of level and temperature by means of a PLC and the visualization of information in a Human Machine Interface (HMI), an experimental documentary methodology was used.A proportional control with PWM was applied in the PLC to control the variables, level and temperature tests were performed with and without water discharge in the tank.The results showed that the proportional control was sufficient to control the level and temperature of the tank with gain of 3 and 5 with an error ±5 mm or ±2% and± 0.5 0 C or ±1.56% with discharge respectively, the system is open so it can be applied and test the response under various types of control.
