1.用户存储器容量
PLC中用户存储器一般由用户程序存储器和数据存储器组成,小型PLC的用户存储器容量多为几K字节,而大型PLC可达到几M字节。
2.输入输出点数
输入输出的点数决定了PLC可控制的输入开关信号和输出开关信号的总体数量。
3.扫描速度
扫描速度通常指PLC扫描1 K字节用户程序所需的时间,一般以ms/K为单位。
4.编程指令的种类和功能
某种程度上用户程序所完成的控制功能受限于PLC指令的种类和功能。PLC指令的种类和功能越多,用户编程则越方便简单。
5.内部寄存器的配置和容量
用户编制PLC程序时,需要大量使用PLC内部的寄存器存放变量、中间结果、定时计数及各种标志位等数据信息。因此内部寄存器的数量直接关系到用户程序的编制。
6.PLC的扩展能力
在进行PLC选型时,其扩展性是一个非常重要的因素。一般来说可扩展性包括存储容量的扩展、输入输出点数的扩展、模块的扩展、通信联网功能的扩展等。
