基于现场总线的电动执行机构应用实例

随着对过程控制系统安全性要求的不断提高,现场总线控制方案正逐渐取代传统控制方案,成为越来越多工程的常规控制手段之一。作为重要控制终端之一的电动执行机构也要不断适应现场总线技术变化的需求。文章通过一工程实例,概述如何选取适合项目的现场总线方案,保证系统安全、可靠、高效运行。

Example for Using Electrical Actuator base on Fieldbus Control

Along with the secure requirement of process control system enhancing,fieldbus control scheme is going to be regular and will replace the traditional control system gradually in more and more projects.As one of the critical control elements,electrical actuator should be updated and fir for project requirement via various fieldbus.Here is a typical project to summarize how to choose an appropriate fieldbus scheme,ensuring the security,reliability and efficiency of the control system.
