FOXBORO 130M-N4 气动控制器模块一般远离控制中心，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。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，现场控制单元通常分为基本型和扩展型两种，FOXBORO 130M-N4 气动控制器模块所谓基本型就是各种插件安装在一个插件箱中，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 FOXBORO 130M-N4 pneumatic controller module is generally located away from the control center, close to the site, and its highly modular structure can be configured into process control units ranging in size from a few monitoring points to hundreds of monitoring points, depending on the needs of process monitoring and control. The structure of the field control unit is composed of a number of decentralized boards (or cards) installed in the board box according to a certain logical or physical sequence, and the bus connection between the field control unit and the control management level is adopted to realize information exchange.

The hardware configuration of the onsite control unit must be as follows: Plug-in configuration Configure hardware devices such as host plug-ins (CPU plug-ins), power plug-ins, I/O plug-ins, and communication plug-ins based on system requirements and control scale. Hardware redundancy configuration Redundant configuration of key devices is an important means to improve the reliability of DCS. DCS can realize redundant configuration of host plug-ins, power plug-ins, communication plug-ins, network plug-ins, and critical I/O plug-ins. Hardware installation of different DCS, for the installation of various plug-ins in the plug-in box, there will be corresponding provisions in the logical order or physical order. In addition, the field control unit is usually divided into basic type and extended type two, FOXBORO 130M-N4 pneumatic controller module the so-called basic type is a variety of plug-ins installed in a plug-in box, but more often when the need for extensible structural form, that is, a field control unit also includes a number of digital input/output expansion units, The bus is connected to each other.
