Abstract

Electro-pneumatic and hydraulic sequential circuits are one of the industrial automation cornerstones. Programmable Logic Controllers (PLC) are one of the main components of these circuits; however, its application is highly dependent on programmer’s skills. Different methods are found in the literature to design those systems, but they involve complex analyses and intuitive strategies in cases that the actuators extend and retract more than once within the cycle of movements, and within simultaneous movements. The design of sequential circuit is a challenge, despite the fact it is a discrete event system, and, most of times, there are mandatory hardware restrictions. As a consequence, the resulting circuits mostly require a large number of valves and electronic components and it depends on user expertise in order to be implemented. The objective of this work is to describe a novel method that can be applied in the design and implementation of circuits using PLC's, eliminating intuitive solutions. Examples are presented to illustrate the theoretical procedures and experimental tests performed to validate the method. The results prove the generality of this work, the simplicity of its implementation, and introduce a bridge between design and implementation of electro pneumatics and electro/hydraulics circuits with PLC's.
