Desenvolvimento de um Sistema de Supervisão e Controle de uma Esteira Separadora de Peças

Abstract

Currently, automated systems have evolved into increasingly flexible, intelligent, and connected solutions, in which the PLC plays a central role in process control. Programming these controllers can be done in Ladder, a language that is easy to interpret and simulates electrical circuits, or in GRAFCET, a graphical tool designed to describe sequential stages of operation. To ensure that the data generated in these systems is integrated and made available across different automation layers, the OPC protocol is used, providing standardized communication between the PLC and supervisory software, thus consolidating an efficient and interconnected production environment. This work presents the development of a supervision and control system applied to a parts sorting conveyor. For this purpose, a commercial Programmable Logic Controller (PLC) was adopted to practically and realistically reproduce typical industrial environment scenarios, providing a didactic approach to the project. The control logic was developed using the Ladder language and the GRAFCET methodology, both essential for modeling and implementing sequential processes. This project also explores concepts of Supervisory Control and Data Acquisition (SCADA) systems and OPC communication, highlighting the growing importance of hardware and software integration as the foundation for new industrial solutions.
