HIMAEABT3 B9302 997009302  卡件模块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。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。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。

HIMAEABT3 B9302 997009302  卡件模块正经历着一场前所未有的变革，开始向网络化方向发展。控制系统的结构从最初的CCS（计算机集中控制系统），到第二代的DCS（分散控制系统），发展到现在流行的FCS（现场总线控制系统）。对诸如图像、语音信号等大数据量、高速率传输的要求，又催生了工业以太网与控制网络的结合。

HIMA EABT3 B9302 997009302 card module 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. The distributed control system is composed of input and output modules, communication modules, controllers and human-machine interfaces. It is an industrial automation control system based on controllers and field equipment, which collects relevant process signals into the system, monitors or other control operations by the operation station, and takes decentralized control, centralized operation and hierarchical management as its main characteristics. Compared with 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.

HIMA EABT3 B9302 997009302 Card modules are undergoing an unprecedented change and are beginning to develop in the direction of networking. The structure of the control system from the initial CCS (computer centralized control system), to the second generation of DCS (decentralized control system), to the now popular FCS (fieldbus control system). The demand for large data volume and high speed transmission, such as images and voice signals, has spawned the combination of industrial Ethernet and control network.
