PLC的容量选择 PLC的容量包括I／O点数和用户存储容量两个方面。
1．I／O点数
PLC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I／O点最少，但必须留有一定的备用量。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％的备用量来确定。
2．用户存储容量
用户存储容量是指PLC用于存储用户程序的存储器容量。需要的用户存储容量的大小由用户程序的长短决定。
一般可按下式估算，再按实际需要留适当的余量（20％－30％）来选择。
存储容量=开关量I／O点总数X10十模拟量通道数X100绝大部分PLC均能满足上式要求。应当要注意的是：当控制系统较复杂。数据处理量较大时，可能会出现存储容量不够的问题，这时应特殊对待。
