SPBRC410过程控制级具体实现了信号的输入、变换、运算和输出等分散控制功能。在不同的DCS中,过程控制级的控制装置各不相同,如过程控制单元、现场控制站、过程接口单元等等,但它们的结构形式大致相同,可以统称为现场控制单元FCU。SPBRC410过程管理级由工程师站、操作员站、管理计算机等组成,完成对过程控制级的集中监视和管理,通常称为操作站。DCS的硬件和软件,都是按模块化结构设计的,所以DCS的开发实际上就是将系统提供的各种基本模块按实际的需要组合成为一个系统,SPBRC410这个过程称为系统的组态。SPBRC410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。SPBRC410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。
SPBRC410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。SPBRC410硬件安装 不同的DCS,对于各种插件在插件箱中的安装,会在逻辑顺序或物理顺序上有相应的规定。另外,SPBRC410现场控制单元通常分为基本型和扩展型两种,所谓基本型就是各种插件安装在一个插件箱中,SPBRC410但更多的时候时需要可扩展的结构形式,即一个现场控制单元还包括若干数字输入/输出扩展单元,相互间采用总线连成一体。

The SPBRC410 process control level specifically implements decentralized control functions such as signal input, transformation, operation, and output. In different DCS, the control devices at the process control level are different, such as process control units, on-site control stations, process interface units, etc., but their structural forms are roughly the same and can be collectively referred to as on-site control units (FCUs). The SPBRC410 process management level is composed of an engineer station, an operator station, a management computer, etc., which completes centralized monitoring and management of the process control level, commonly known as an operation station. The hardware and software of DCS are designed according to a modular structure, so the development of DCS is actually to combine various basic modules provided by the system according to actual needs into a system. The process of SPBRC410 is called system configuration. The SPBRC410 on-site control unit is generally located far from the control center and installed near the site. Its highly modular structure can be configured as a process control unit with varying scales from several monitoring points to hundreds of monitoring points according to the needs of process monitoring and control. The structure of the SPBRC410 field control unit is composed of many functionally dispersed plug-in boards (or cards) installed in a certain logical or physical order in the plug-in box. Each field control unit and its connection with the control management level are connected by bus to achieve information exchange.
The hardware configuration of the SPBRC410 on-site control unit needs to complete the following tasks: the configuration of the plugin should be based on the system requirements and control scale, including configuring hardware devices such as the host plugin (CPU plugin), power plugin, I/O plugin, communication plugin, etc; Hardware redundancy configuration is an important means to improve the reliability of DCS by configuring critical equipment with redundancy. DCS can usually achieve redundancy configuration for host plugins, power plugins, communication plugins, and network and critical I/O plugins. SPBRC410 has different DCS hardware installations, and there will be corresponding regulations in logical or physical order for the installation of various plugins in the plugin box. In addition, the SPBRC410 field control unit is usually divided into two types: basic type and extended type. The so-called basic type refers to the installation of various plugins in a plug-in box. However, more often than not, the SPBRC410 requires an expandable structure, which means that a field control unit also includes several digital input/output expansion units, which are connected to each other through a bus to form a whole
