横河CS3000功能块说明<Toc> <Ind> <D1. Regulatory Control> D1-1IM 33S01B30-01ED1. Regulatory Control调整控制The regulatory control performs control computation processing using analog process values for process monitor and process control. The function blocks that provide the regulatory control function are referred as “regulatory control blocks.”调整控制是利用过程监控及过程控制中的模拟过程量来进行控制计算处理的。
This chapter presents a detailed description of the function of each of the regulatory control blocks, excluding the Foundation Fieldbus faceplate block. 这章将逐个介绍每个调整控制块的功能，包括基金会现场总线的面板功能块。

The function blocks that perform the this regulatory control are referred as “regulatory control blocks.”调整控制是FCS的一个基本控制单元，执行过程监控的控制计算处理。
我们把执行这个调整控制的功能块称之为调整控制块。
The regulatory control blocks include Input indication blocks, controller blocks, manual loader blocks, signal set blocks, signal limiter blocks, Signal selector blocks, signal distribution blocks, pulse-count blocks, alarm blocks and YS blocks. The figure below shows the position of the regulatory control function in the basic control architecture:调整控制功能块包括输入控制块，控制器块，手动设备块，信号设置块，信号限制块，信号选择块，信号分布块，脉冲计数块，报警块和YS块。
下图说明调整控制功能块在基本控制体系的位置：D1.1 Regulatory Control Blocks调整控制块The regulatory control blocks are the function blocks that perform control computation processing mainly on the analog input as input signals. The calculated results are used for process monitor and process control.调整控制块主要是一种主要以模拟输入作为输入信号进而执行控制计算处理的功能块。
计算结果用于过程监控和控制。
The regulatory control blocks support the following types of processing: input processing, control computation processing, output processing and alarm processing.调整控制块支持以下几种处理：输入处理，控制计算处理，输出处理和报警处理。
■Structure of Regulatory Control Blocks调整控制块的结构The function blocks that provide the regulatory control function are called “regulatory control blocks.”提供调整控制功能的功能块称之为调整控制块。
The regulatory control blocks perform control computation processing mainly on analog signals (analog values) as input values. The results of control computation processing performed by the regulatory control blocks are output as manipulated output values (MV).调整控制块执行控制计算处理主要是通过模拟信号（模拟量）作为输入量。
调整控制功能块计算处理的结果作为操作输出值（MV）输出。

●Alarm Processing 报警处理Detects an abnormality in the process variable (PV) or manipulated output value (MV) and notifies the operation and monitoring functions.在过程值（PV）或操作输出值（MV）中发现一个异常，给操作监控功能发出通报。
Control computation processing can be performed independently via data setting or data reference between the function blocks, without involving input processing or output processing.控制计算处理能够通过数据设定或功能块之间的一些相关数据的设定独立的进行处理功能，而不用包括输入和输出处理SEE ALSO参考Refer to the following sections for the input processing, output processing, and alarm processing that are common to a multiple number of regulatory control blocks. 参考以下关于输入处理，输出处理和报警处理的章节，这些都是大多数调整控制块的公共部分。
• For input processing, see chapter C3, “Input Processing.”• For output processing, see chapter C4, “Output Processing.”• For alarm processing, see chapter C5, “Alarm Processing - FCS.”The characteristics and control computation processing functions of the regulatory control blocks are explained as control action in the sections for individual function blocks in the chapters from D1.3.在D1.3单独的功能块介绍部门中，调整控制块的特性和控制计算处理功能将作为控制作用予以解释。
