Projeto, desenvolvimento e validação de uma unidade remota Modbus microcontrolada

Abstract

Microcontrolled remotes are used to control and acquire data from remotely located equipment and transfer this data to a central controller. This work presents the design, development and validation of a remote MODBUS microcontrolled. This equipment is designed to work with interface boards for signs of digital inputs, digital outputs, and communication via MODBUS protocol. We developed four printed circuit boards that operate in conjunction with a microcontroller PIC18F2550. Through a program developed in C language, the microcontroller executes a communication routine for the industrial network MODBUS protocol in conjunction with the USB standard. To validate the operation of the equipment has been developed through an application of a supervisory software, this application works through a computer configured as MODBUS master. From your computer you can remotely trigger the device and also receive remote signals. The intention of this project demonstrate that it is possible to develop industrial automation equipment using tools and resources available.
