DCS具有通用性强、系统组态灵活、控制功能完善、数据处理方便、显示操作集中、人机界面友好、安装简单规范化、调试方便、运行安全可靠等特点，在国内外电力、石油、化工、冶金、轻工等生产领域广泛使用。DCS的安全、可靠与否对于保证机组的安全、稳定运行至关重要，若发生问题将有可能造成设备的严重损坏甚至人身安全事故。

数字量输入输出信号就是开关量信号，1或者0,

模拟量信号，有2种，电压或者电流信号，一般是变送器传过来的信号，比如用压力变送器检测水管压力，它会输出一个模拟信号4-20ma或者0-10V的信号给PLC，PLC来进行数据处理。

开关量输入点(DI),处理开关量输入信号.

模拟量输入点(Al),处理模拟量输入信号(O-20mADC,O-5VDC).电阻信号(含热电阻)输入点处理热电阻或一般电阻信号.高速脉冲输入点,处理高速脉冲信号.

电压(含热电偶)输入点,处理电压输入或热电偶信号.

还有通讯,用于和上位机交换数据或控制下级控制器仪表驱动器等1.2数字量/模拟量输入模块区别根据现场输入信号的不同，可将输入模块分为开关量输入模块和模拟量输入模块

DCS has the characteristics of strong versatility, flexible system configuration, perfect control function, convenient data processing, centralized display operation, user-friendly human-machine interface, simple and standardized installation, convenient debugging, safe and reliable operation, etc., widely used in domestic and foreign electric power, petroleum, chemical, metallurgy, light industry and other production fields. The safety and reliability of DCS is crucial to ensure the safe and stable operation of the unit, and if there is a problem, it may cause serious damage to the equipment and even personal safety accidents.

The digital input/output signal is the switching signal, 1 or 0,

Analog signals, there are two, voltage or current signals, generally the signal transmitted by the transmitter, such as the pressure transmitter to detect the pressure of the water pipe, it will output an analog signal 4-20ma or 0-10V signal to the PLC, PLC for data processing.

The switching input point (DI) processes the switching input signal.

Analog input point (Al), processing analog input signal (O-20mADC,O-5VDC). Resistance signals (including thermal resistance) The input point processes thermal resistance or general resistance signals. High-speed pulse input point, processing high-speed pulse signal.

Voltage (including thermocouple) input point, processing voltage input or thermocouple signal.

There is also communication, which is used to exchange data with the host computer or control the instrument driver of the lower controller 1.2 digital/analog input module difference According to the difference of the field input signal, the input module can be divided into the switching input module and the analog input module
