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。

就本质而言，现场控制单元的结构形式和配置要求与模块化PLC的硬件配置是一致的。操作站操作站用来显示并记录来自各控制单元的过程数据，是人与生产过程信息交互的操作接口。FOXBORO 130M-N4 气动控制器模块典型的操作站包括主机系统、显示设备、键盘输入设备、信息存储设备和打印输出设备等，主要实现强大的显示功能（如模拟参数显示、系统状态显示、多种画面显示等等）、报警功能、操作功能、报表打印功能、组态和编程功能等另外，DCS操作站还分为操作员站和工程师站。FOXBORO 130M-N4 气动控制器模块从系统功能上看，前者主要实现一般的生产操作和监控任务，具有数据采集和处理、监控画面显示、故障诊断和报警等功能。后者除了具有操作员站的一般功能以外，还应具备系统的组态、控制目标的修改等功能。从硬件设备上看，多数系统的工程师站和操作员站合在一起，仅用一个工程师键盘加以区分。

The FOXBORO 130M-N4 pneumatic controller module 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 a scale ranging from several monitoring points to hundreds of monitoring points according to the needs of process monitoring and control. The structure of the on-site 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 on-site control unit and its connection with the control management level are connected by bus to achieve information exchange. The hardware configuration of the on-site control unit needs to complete the following tasks: the configuration of plugins should be based on the system requirements and control scale, including the configuration of host plugins (CPU plugins), power plugins, I/O plugins, communication plugins, and other hardware devices; 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. Different DCS hardware installations have corresponding regulations on the logical or physical order of installing various plugins in the plugin box. In addition, on-site control units are usually divided into two types: basic and extended. The FOXBORO 130M-N4 pneumatic controller module is a basic type where various plugins are installed in one plugin box. However, more often than not, an expandable structural form is required. That is, one on-site control unit also includes several digital input/output expansion units, which are connected to each other through a bus.

Essentially, the structural form and configuration requirements of the on-site control unit are consistent with the hardware configuration of the modular PLC. The operation station is used to display and record process data from various control units, and is an interface for exchanging information between humans and production processes. The typical operation station of the FOXBORO 130M-N4 pneumatic controller module includes the host system, display equipment, keyboard input equipment, information storage equipment, and print output equipment. It mainly realizes powerful display functions (such as analog parameter display, system status display, multiple screen displays, etc.), alarm functions, operation functions, report printing functions, configuration and programming functions. In addition, the DCS operation station is also divided into an operator station and an engineer station. From the perspective of system functions, the FOXBORO 130M-N4 pneumatic controller module mainly realizes general production operations and monitoring tasks, and has functions such as data acquisition and processing, monitoring screen display, fault diagnosis and alarm. In addition to the general functions of an operator station, the latter should also have functions such as system configuration and modification of control objectives. From a hardware device perspective, the engineer station and operator station of most systems are combined and distinguished by only one engineer keyboard.
