The Development Of Smart Temperature Transmitter On Base Of WorldFIP Protocol

Along with the growing technique of Fieldbus, the traditional control system steps into a new phase, which is Fieldbus control system (FCS) .In order to meet the requirement of local instrument by FCS, It is significant and urgent to develop a smart transmitter with fieldbus communication. On the base of the comparison of the popular fieldbus technique, the paper analyses WorldFIP protocol in detail and introduces the main developing tools; After dissecting TT302,which conforms to Fieldbus Foundation protocol , the paper gives the primary differences between smart transmitters with fieldbus communication and traditional instruments, explains the advantage of the former and establish the developing aims.Then the paper realize the temperature transmitter from two ways: hardware and software, land is proved on the emulate system. The results show its enhanced capability in the fieldworking instruments' integrative automation.At last, the paper explores the direction of coming works.
