■ Functions of the Regulatory Control Blocks 调整控制块的功能

The regulatory control blocks have the following four processing functions:调整控制块有以下四种处理功能：

● Input Processing   输入处理

Receives a signal from the input terminal and outputs a process variable (PV).从输入端接收一个信号，输出一个过程值（PV）

● Control Computation Processing 控制计算处理

Performs control computation processing by reading the process variable (PV) and outputs a manipulated output value (MV). 读取过程值（PV）执行控制计算处理，输出一个操作输出值（MV）

● Output Processing  输出处理

Reads the manipulated output value (MV) and outputs the result of control computation processing to the output terminal as an output signal.读取操作输出值（MV），输出控制计算处理的结果到输出端作为输出信号。

● 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
