Application of Binodal Logic in the Development of a Sequence of Pneumatic Cylinders Using a Didactic Briefcase

In recent years, industries have implemented new technologies in their processes; currently, professionals who come from university centers have a serious deficiency in their practical skills. To improve these qualities in the engineering student, modern teaching equipment must be acquired, with cutting-edge technology, which implies that greater economic resources must be spent to cover these deficiencies. For this reason, a proposal arises to develop a system that connects to the equipment that educational institutions have, but along the lines of automation, that has the technology of the moment and that can be moved to different spaces, that are portable. In the development of the proposal, a didactic briefcase is presented, the same one that has as main element a PLC S7 - 1200, carries all the inputs and outputs passing through the corresponding protections with cables to: terminal blocks, potentiometers, pilots lights, correspondingly, which are located in the front part of the equipment. The system variables can be visualized through an HMI. With this research, the students can implement their automation applications, to check the operation of the equipment, the didactic module is taken to the electropneumatics laboratory, in the binodal logic, with which, the effectiveness of the operation of the didactic briefcase is checked.
