控制系统需要建立信号的输入和输出通道，这就是I/O,DCS中的I/O一般是模块化的，一个I/O模块上有一个或多个I/O通道，用来连接传感器和执行器（调节阀）。

常用的I/O信号一般分为：AI、PI、AO、DI和DO。

AI－－模拟量输入信号

PI－－脉冲量输入信号

AO－－模拟量输出信号

DI－－数字量输入信号

DO－－数字量输出信号

The control system needs to establish the input and output channels of the signal, which is I/O, I/O in DCS is generally modular, an I/O module has one or more I/O channels, used to connect the sensor and the actuator (regulator).

Commonly used I/O signals are generally divided into: AI, PI, AO, DI and DO.

AI- analog input signal

PI- pulse volume input signal

AO- analog output signal

DI- digital input signal

DO- digital output signal

采用简明的梯形图、逻辑图或语句表等编程语言，而无需计算机知识，因此系统开发周期短，现场调试容易。另外，可在线修改程序，改变控制方案而不拆动硬件。

由于PLC的输出元件被封装在印制电路板上，SE3006并且连接至端子板，若将连接输出元件的负载短路，将烧毁印制电路板

Using concise ladder diagram, logic diagram or statement table programming language, without computer knowledge, so the system development cycle is short, the field debugging is easy. In addition, the program can be modified online to change the control scheme without dismantling the hardware.

Since the PLC output component is packaged on the printed circuit board, SE3006 and connected to the terminal board, if the load connected to the output component is short-circuited, the printed circuit board will be burned
