Visão Geral
Este curso ensina como utilizar o Telegraf integrado ao protocolo Modbus, tanto em Modbus TCP quanto Modbus RTU, para coleta de dados industriais. O aluno aprenderá a configurar o Modbus Input Plugin, mapear registradores, interpretar dados e aplicar boas práticas para garantir uma coleta confiável em ambientes industriais.
