PLC的容量包括I／O点数和用户存储容量两个方面。
(一)I／O点数的选择
PLC平均的I／O点的价格还比较高，因此应该合理选用PLC的I／O点的数量，在满足控制要求的前提下力争使用的I／O点***少，但必须留有一定的裕量。
通常I／O点数是根据被控对象的输入、输出信号的实际需要，再加上10％~15％的裕量来确定。
(二) 存储容量的选择
用户程序所需的存储容量大小不仅与PLC系统的功能有关，而且还与功能实现的方法、程序编写水平有关。一个有经验的程序员和一个初学者，在完成同一复杂功能时，其程序量可能相差25％之多，所以对于初学者应该在存储容量估算时多留裕量。
PLC的I／O点数的多少，在很大程序上反映了PLC系统的功能要求，因此可在I／O点数确定的基础上，按下式估算存储容量后，再加20％~30％的裕量。
存储容量（字节）＝开关量I／O点数×10 ＋ 模拟量I／O通道数×100
另外，在存储容量选择的同时，注意对存储器的类型的选择。
