EM203  是福建华瑞兴自动化设备有限公司主营的优势产品，现场控制单元一般远离控制中心，安装在靠近现场的地方，其高度模块化结构可以根据过程监测和控制的需要配置成由几个监控点到数百个监控点的规模不等的过程控制单元。
现场控制单元的结构是由许多功能分散的插板（或称卡件）按照一定的逻辑或物理顺序安装在插板箱中，各现场控制单元及其与控制管理级之间采用总线连接，以实现信息交互。
现场控制单元的硬件配置需要完成以下内容：
插件的配置 根据系统的要求和控制规模配置主机插件（CPU插件）、电源插件、I/O插件、通信插件等硬件设备；
硬件冗余配置 对关键设备进行冗余配置是提高DCS可靠性的一个重要手段，DCS通常可以对主机插件、电源插件、通信插件和网络、关键I/O插件都可以实现冗余配置。
