Abstract: During the transition from DCS to FCS, the problem of the interface of conventional instrument and FCS appears. To solve this problem, the paper gives the design of the Fieldbus-current Converter. The character of the WorldFIP is introduced. The elements of the converter, the circuit diagram of the interface and the design of the software are emphasized.
