Design of Isolated MultiChannel LONWORKS Data Acquisition Node

Abstract The design of an isolated multichannel LONWORKS data acquisition node is described in this paper.Firstly,the function of data acquisition and the importance of developing LONWORKS data acquisition nodes are briefly introduced.Secondly,the overall desing of the node is discussed,on the basis of considering practical production process the specification of the node is proposed.Thirdly,key hardware circuits are discussed and cautions in design are given.In the end,software design of the node is introduced.
