PM645B 执行程序指令

依靠先进的工业网络技术可以迅速有效地收集、传送生产和管理数据。因此，网络在自动化系统集成工程中的重性越来越显著，甚至有人提出“网络就是控制器"的观点说法，PLC具有通信联网的功能，它使PLC与PLC之间、PLC上位计算机以及其他智能设备之间能够交换信息，形成一统一的整体，实现分散集中控制。多数PLC具有RS一232口，

数据处理:处理器模块可以对内存中的数据进行各种运算和操作，如加法、减法、乘法、除法等，以及逻辑运算和位运算等。控制和管理:处理器模块还负责控制和管理计算机系统的各个部件，如内存、输入输出设备等，确保它们之间的协调和正常运行。

Relying on advanced industrial network technology, production and management data can be collected and transmitted quickly and efficiently. Therefore, the importance of the network in the automation system integration project is more and more significant, and even some people put forward the "network is the controller" point of view, PLC has the function of communication networking, it enables the exchange of information between PLC and PLC, PLC host computer and other intelligent devices to form a unified whole, to achieve decentralized centralized control. Most PLCS have RS-232 ports,

Data processing: The processor module can perform various operations and operations on the data in memory, such as addition, subtraction, multiplication, division, etc., as well as logical operations and bit operations. Control and management: The processor module is also responsible for controlling and managing the various components of the computer system, such as memory, input and output devices, etc., to ensure coordination and normal operation between them.
