Abstract in Portuguese
Este trabalho apresenta e implementa um algoritmo de escalonamento para a tecnologia Foundation Fieldbus. O algoritmo denominado FFSMART escalona as mensagens de comunicação cíclica ou periódica entre os dispositivos de campo que estão no barramento fieldbus. Trata-se de um algoritmo de escalonamento pré-run-time, que permite atender às restrições de precedência dos blocos funcionais, personalizando e otimizando o uso dos recursos do sistema. O algoritmo foi implementado na linguagem de programação Visual Basic e sua validação ocorreu em um ambiente real de aplicação através de estratégias de configuração, cujos resultados foram satisfatórios.

Abstract in English
This dissertation presents and implements a scheduling algorithm for the Foundation Fieldbus technology. The algorithm named FFSMART schedules cyclic or periodic communication messages among field devices connected to a fieldbus. The FFSMART is a pre-runtime scheduling algorithm, which allows meeting the restrictions of precedence from function blocks, customizing and optimizing the use of the system resources. The algorithm was implemented using the Visual Basic programming language and validated in a real application environment using configuration strategies, and the results were satisfactory.
