DSQC352 励磁测量单元板 智能工业的智能自动化

PLC的通信包括PLC之间、PLC与上位计算机之间以及PLC与其他智能设备间的通信。

PLC系统与通用计算机可以直接或通过通信处理单元、通信转接器相连构成网络，以实现信息的交换，并可构成“集中管理、分散控制”的分布式控制系统，满足工厂自动化(FA)系统发展的需要，各PLC系统或远程I/O模块按功能各自放置在生产现场分散控制，然后采用网络连接构成集中管理的分布式网络系统。

在其提出的全集成自动化(TIA)的系统概念中，核心内容即包括组态和编程的集成、数据管理的集成以及通信的集成。通信网络是这个系统重要的、关键的组件，提供了部件和网络间完善的工业通信。

The communication of PLC includes the communication between PLC, PLC and upper computer, and PLC and other intelligent devices.

PLC system and general purpose computer can be directly or through the communication processing unit, communication adapter connected to form a network to achieve the exchange of information, and can form a "centralized management, decentralized control" distributed control system to meet the needs of the development of factory automation (FA) system, each PLC system or remote I/O module according to the function of their respective placed in the production site decentralized control. Then network connection is used to form a distributed network system of centralized management.

In the system concept of fully integrated Automation (TIA), the core content includes the integration of configuration and programming, data management and communication. The communication network is an important and critical component of this system, providing complete industrial communication between components and the network.
