In the last years it was observed that there has been a great evolution related to industrial automation as well as the evolution regarding DSP (digital signal processor) and industrial networks. The use of DSP, related to artificial intelligence techniques and neural network, permits gradually the incorporation of intelligence onto terminal control units such as sensors and actuators. This paper presents the development of a intelligent functionality system to process sensor signals through remote parameterization of a neural network in a DSP board, enabling the increase in field device processing capability (intelligence)
