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。
