Resumen
In this research, a control and monitoring system of electrical parameters was designed through the Modbus communication protocol, using the Python programming language. For this purpose, indispensable electrical parameters were identified in the production processes that allow us to obtain the necessary information to optimize time and resources. The programming in the PLC S7-1200 was done in the TIA PORTAL, through the Modbus communication, the frequency inverter SIMATICS V20 and the electrical parameters meter SENTRON PAC 3100 were coupled, which allow to obtain the data that later will be reflected in the HMI. By means of the Python programming language using the Snap7 library, the code of the graphic interface was developed, which shows the data in real time of the electrical parameters required in the process. By means of data comparison, the permissible relative error was calculated, obtaining as a result that the values of the variables measured through physical equipment and shown in the HMI do not exceed 1%, that is to say, the data are highly reliable. In addition, it was found that the design would make it cheaper to implement a system that requires a license for use, which is adapted to the requirements of small and medium-sized industries.
