Simulación de una red Maestro-Esclavo para el proceso de pasteurización de la leche : Simulación de una red Maestro-Esclavo.

Abstract

This degree work was developed based on the automation of industrial processes, the application of basic control commands such as sequential control, timers, counters and the design standards of the Human Machine Interface to subsequently simulate a Master-Slave network of the milk pasteurization process in the PORTAL TIA V15 software. It was configured in a software project through the use of system blocks called TSEND and TRCV, which established the correct connection between both PLC'S. of the Master-Slave network. Based on the automation requirements of the system, the control algorithms were developed in FBD language, where a FB template was used both for the selection of the operation mode and for the manual and automatic control of each stage of the process and special blocks for the simulation of level and temperature sensors. Different HMI windows were developed for the supervision and control of all stages of the industrial system. These windows include the areas of the process, reception, pasteurization, milk packaging and curves of the process variables. In addition, the PLCSIM tool of the Master PLC was used to command the different states of the process through the Slave PLC, which controls the operation stages of the process. Finally, communication tests were performed between the controllers, the HMI and through videos, both the industrial network configuration and the simulation of the entire process in the TIA V15 PORTAL were shown to verify its operation.
