PROCESS IMPROVEMENT VIA PROGRAMMABLE LOGIC CONTROLLER: an analysis of Modicon M221 applications in Industry 4.0

análise de aplicações do Modicon M221 na Indústria 4.0

Abstract

The present research has as its main objective to demonstrate how the use of the Modicon M221 Programmable Logic Controller (PLC) contributes to the improvement of industrial processes and greater efficiency and safety, in addition to system automation. Through a practical example of the equipment’s application, it seeks to provide technical and didactic support for students and professionals who work in or are interested in the field of industrial automation. At the same time, it analyzes the various programming techniques of PLCs, devices that provide numerous benefits such as the reduction of failures and the increase of operational reliability. Specifically, in the case of the M221, the intention is to highlight how its application enhances productivity, integration with supervisory systems, and workplace safety. To assess these benefits, a practical case study was carried out in a packaging industry located in Santa Catarina, a state recognized as a national hub in terms of automation and technological innovation in industry. Thus, this research goes beyond the theoretical approach to the equipment, as it seeks to understand its effectiveness through a real manufacturing environment, aligned with the new demands brought by Industry 4.0.
