PCD232A工业自动化是指机器设备或生产过程在不需要人工直接干预或较少干预的情况下，按预期的目标实现测量、操纵等信息处理和过程控制的统称。按功能划分，自动化控制具体包括控制系统、驱动系统、反馈系统、执行系统、运动控制系统等，其中的控制系统被称为是工厂的“大脑”，是工业生产尤其是流程工业的中枢和基础，其安全稳定性、效率性直接影响生产流程各个生产环节。传统控制系统一般包括仪器仪表系统、DCS系统、PLC系统、SIS系统、SCADA系统、执行调节系统等。

DCS，即集散控制系统，由输入输出模块、通信模块、控制器和人机界面组成，是一种以控制器和现场设备为基础，将相关工艺信号汇集到系统中，由操作站进行监视或其他控制操作，以分散控制、集中操作、分级管理为主要特征的工业自动化控制系统。

与PLC侧重于局部逻辑控制相比，DCS更注重模拟量的控制，因此DCS系统拥有更强的数据传输和管理能力，这也是大型项目广泛应用DCS系统的主要原因。

PCD232A Industrial automation refers to the machine equipment or production process in the case of no direct manual intervention or less intervention, according to the expected goals to achieve measurement, manipulation and other information processing and process control. According to the functional division, automation control specifically includes control system, drive system, feedback system, execution system, motion control system, etc. The control system is known as the "brain" of the factory, is the center and foundation of industrial production, especially process industry, and its safety, stability and efficiency directly affect the production process of each production link. The traditional control system generally includes instrumentation system, DCS system, PLC system, SIS system, SCADA system, executive regulation system and so on.

DCS, that is, distributed control system, composed of input and output modules, communication modules, controllers and human-machine interfaces, is a controller and field equipment based, the relevant process signals gathered into the system, by the operation station for monitoring or other control operations, decentralized control, centralized operation, hierarchical management as the main characteristics of the industrial automation control system.

Compared with PLC, which focuses on local logic control, DCS pays more attention to analog control, so DCS system has stronger data transmission and management capabilities, which is also the main reason why DCS system is widely used in large-scale projects.
