1、中央处理单元(CPU)
(1)诊断plc电源、内部电路的工作状态及编制程序中的语法错误。
(2)采集现场的状态或数据,并送入PLC的寄存器中。
(3)逐条读取指令,完成各种运算和操作。
(4)将处理结果送至输出端。
(5)响应各种外部设备的工作请求。
2、存储器 (ROM/RAM)
(1)系统程序存储器(ROM) 用以存放系统管理程序、监控程序及系统内部数据,PLC出厂前已将其固化在只读存储器ROM或PROM中,用户不能更改。
(2)用户存储器(RAM) 包括用户程序存储区和工作数据存储区。这类存储器一般由低功耗的CMOS-RAM构成,其中的存储内容可读出并更改。掉电会丢失存储的内容,一般用锂电池来保持。
注意: PLC产品手册中给出的“存储器类型”和“程序容量”是针对用户程序存储器而言的
3、可编程控制器输入端口电路
开关量输入接口电路:采用光电耦合电路,将限位开关、手动开关、编码器等现场输入设备的控制信号转换成CPU所能接受和处理的数字信号。
PLC的输入接口电路(直流输入型)
