3、存储器

PLC存储器是保存程序和数据的地方，分内制式和外插式两种，存储器容量在512~128M字节之间，一定要根据实际情况选取足够大的存储器，并且要求有一部分空余作为缓存。

PLC存储器按照类型可分随机存储器（RAM）、只读存储器（ROM）、可擦除只读存储器（EPROM）等。RAM可以任意读写，在掉电后程序只能保持一段时间，最适合于在自控系统调试时使用。ROM只能读不能写，程序是由厂家或开发商事先固化的，不能更改，即使失电也不丢失。EPROM与ROM只是EPROM通过特殊的方式（如紫外线）可以擦除再写，适合于应用在长时间工作而改动不大的系统中。

PLC较继电器控制的另一个优势在于它可以根据实际需要任意更改控制结构（或控制过程），这就要求更改程序方便快捷。

5、是否有专用模块

部分生产厂家的PLC产品提供一些专用模块，如通信模块、PID控制模块、计数器模块、模拟输入/输出模块等。在软件上也提供了与此相对应的程序块，往往只是简单的输入一些参数就能实现，便于用户编程。

五、与监控系统的通信
