Compatibility of FieldBus Control System and Conventional Instrument and the Research of FI Converter |
| |
| Abstract: | This paper discourses the advantage and disadvantage of DCS and the improvement from FCS. It points out that FCS is a better alternate for Industrial Process Control. 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 converter of FieldBus and analog signal, including the operational principle, the selection of the circuit element and the circuit of the interfaces in detail. |
