Implementación de I/O analógicas y digitales en los módulos didácticos PLC’s del LTI-ESFOT.

Abstract

The development of this degree work arose from the need to expand the peripherals of both analog and digital inputs and outputs in the PLC's didactic modules, since usually the students had difficulties when carrying out the control and automation practices of industrial plants in the LTI-ESFOT. In addition to the aforementioned, there was no human-machine interface in the cabinets that allowed the processes to be operated remotely. Based on the problem, two expansion modules SM1223 and SM1234 were installed in each of the three educational modules, providing a greater number of analog and digital inputs and outputs peripherals. This made it possible to control several industrial plants with a single module, since there were already enough peripherals. In addition, a KTP700 basic HMI screen was installed on the cover of the modules in order to speed up communication between the operator and the process that is being carried out. The respective functional tests of the three modules were carried out using industrial plants of the laboratory and other applications such as the ignition of three-phase motors.
