Previous issue date: 2004-12-03 / This work proposes the specification of a new function block according to Foundation Fieldbus standards. The new block implements an artificial neural network, which may be useful in process control applications. The specification includes the definition of a main algorithm, that implements a neural network, as well as the description of some accessory functions, which provide safety characteristics to the block operation. Besides, it also describes the block attributes emphasizing its parameters, which constitute the block interfaces. Some experimental results, obtained from an artificial neural network implementation using actual standard functional blocks on a laboratorial FF network, are also shown, in order to demonstrate the possibility and also the convenience of integrating a neural network to Fieldbus devices / Esta disserta??o apresenta a especifica??o de um novo Bloco Funcional de acordo com o padr?o Foundation Fieldbus, implementando uma Rede Neural Artificial ?til em diversas aplica??es de controle de processos. Essa especifica??o inclui a defini??o do algoritmo central do bloco, que implementa uma RN, e das fun??es acess?rias de forma a prover seguran?a de opera??o, al?m da descri??o dos atributos do bloco, com ?nfase nos par?metros, que formam as interfaces do objeto. Apresentam-se tamb?m os experimentos que foram realizados a partir de uma rede FF de laborat?rio, em que se empregaram apenas blocos padronizados j? existentes, a fim de se verificar a possibilidade e a conveni?ncia de integra??o de algoritmos de RN em dispositivos de campo FF
