一般信息
产品编号：3BSC690104R2
ABB 型号名称：PP345
目录说明：PP345工艺面板

从结构上分，PP345分为固定式和组合式（模块式）两种。固定式PLC包括CPU板、I/O板、显示面板、内存块、电源等，这些元素组合成一个不可拆卸的整体。模块式PLC包括CPU模块、I/O模块、内存、电源模块、底板或机架，这些模块可以按照一定规则组合配置。 


CPU是PLC的核心，起神经的作用，每套PLC至少有一个CPU，它按PLC的系统程序赋予的功能接收并存贮用户程序和数据，用扫描的方式采集由现场输入装置送来的状态或数据，并存入规定的寄存器中，同时，诊断电源和PLC内部电路的工作状态和编程过程中的语法错误等。进入运行后，从用户程序存贮器中逐条读取指令，经分析后再按指令规定的任务产生相应的控制信号，去指挥有关的控制电路。 CPU主要由运算器、控制器、寄存器及实现它们之间联系的数据、控制及状态总线构成，CPU单元还包括外围芯片、总线接口及有关电路。内存主要用于存储程序及数据，是PLC不可缺少的组成单元。
