CNT204/R

CNT204/R PLC的存储器主要包括以下几种。

（1）只读存储器

（2）可编程只读存储器

（3）可擦除可编程只读存储器

（4）电可擦除可编程只读存储器

（5）随机存取存储器

（3）输入/输出（I/O）模块

①开关量输入模块

开关量输入设备是 各种开关、按钮、传感器等，PLC的输入类型通常可以是直流、交流和交直流。输入电路的电源可由外部供给，有的也可由PLC内部提供。

②开关量输出模块

输出模块的作用是将CPU执行用户程序所输出的TTL电平的控制信号转化为生产现场所需的，能驱动特定设备的信号，以驱动执行机构的动作。

（4）编程器

编程器是PLC重要的外部设备，利用编程器可将用户程序送入PLC的用户程序存储器，调试程序、监控程序的执行过程。编程器从结构上可分为以下三种类型。
