Diseño e implementación de un prototipo automatizado de clasificación mediante protocolo modbus TCP/IP

Abstract

This thesis project focuses on the design and implementation of an automated prototype for object classification based on the Modbus TCP/IP industrial communication protocol. The system consists of a main controller, sensors, and actuators that enable the identification and classification of objects according to predefined criteria such as size, weight, and color. Modbus TCP/IP, a widely used technology in industrial automation, is employed to ensure reliable data transmission between the devices involved. The prototype implementation includes the development of an HMI graphical interface in TIA Portal for system monitoring and control, facilitating its operation and understanding. An Arduino with an ENC28J60 Ethernet module is used to communicate with a PLC via the Modbus TCP/IP protocol. The system integrates specific sensors for object classification: a TCS3200 color sensor to identify red, blue, and green colors; an HC-SR04 ultrasonic sensor to determine box sizes. Additionally, a proximity sensor has been incorporated to detect the presence of objects. The classification is performed using an S3003 servo motor, activated according to predefined conditions in the recipes configured in the HMI. This project provides a solution adaptable to production lines, enabling future improvements in automation. Moreover, it strengthens practical learning in Electronic Engineering through the use of industrial technologies and standards.
