摘要
本文针对在DCS向FCS过渡中一个急待解决的问题――常规仪表与现场总线的兼容,开发出基于WorldFIP的现场总线-电流转换器。文章介绍了WorldFIP协议特点,并着重介绍了转换器开发的器件选择,接口电路及软件实现。
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.
