5.2控制规模
控制规模代表PLC控制能力，看其能对多少输入、输出点及对多少路模拟进行控制。
控制规模与速度有关。因为规模大了，用户程序也长，执行指令的速度不快，势必延长PLC循环的时间，也必然会延长PLC对输入信号的响应。为了避免这个情况，PLC的工作速度就要快。所以，大型PLC的工作速度总是比小的要快。
控制规模还与内存区的大小有关。规模大，用户程序长，要求有更大的用户存储区。同时点数多，系统的存储器输入、输出的信号区（输入输出继电器区或称输入、输出映射区）也大。这个区大，相应地内部器件（解释见后）也要增多，这些都要求有更大的系统存储区。
控制规模还与输入、输出电路数有关。如控制规模为1024点，那就得有1024条I/O电路。这些电路集成于I/O模块中，而每个模块有多少路的I/O点总是有数的。所以，规模大，所使用的模块也多。
控制规模还与PLC指令系统有关。规模大的PLC指令条数多，指令的功能也强，才能应付对点数多的系统进行控制的需要。
控制规模是对PLC其它性能指标起着制约作用的指标；也是PLC划分为微、小、中、大和特大型
