控制规模主要指控制开关量的入、出点数及控制模拟量的模入、模出，或两者兼而有之（闭路系统）的路数。但主要以开关量计。模拟量的路数可折算成开关量的点，大致一路相当于8～16点。 

依这个点数，plc大致可分为微型机、小型机、中型机及大型机、超大型机。 

微型机控制点仅几十点，为omron公司的cpm1a系列plc，西门子的logo仅10点。 

小型机控制点可达100多点。如omron公司的c60p可达148点，cqm1达256点。德国西门子公司的s7-200机可达64点。 

中型机控制点数可达近500点，以至于千点。如omron公司c200h机普通配置Zui多可达700多点，c200ha机则可达1000多点。德国西门子公司的s7300机Zui多可达512点。 

大型机：控制点数一般在1000点以上。如omron公司的c1000h、cv1000，当地配置可达1024点。c2000h、cv2000当地配置可达2048点。 

超大型机：控制点数可达万点，以至于几万点。如美国ge公司的90－70机，其点数可达24000点，另外还可有8000路的模拟量。再如美国莫迪康公司的pc－e984--785机，其开关量具总数为32k（32768），模拟量有2048路。西门子的ss－115u－cpu945，其开关量总点数可达8k，另外还可有512路模拟量。等等。 

以上这种划分是不严格的，只是大致的，目的是便于系统的配置及使用。 

一般讲，根据实际的i/o点数，凡落在上述不同范围者，选用相应的机型，性能价格比必然要高；相反，肯定要差些。 

自然，也有特殊情况。如控制点数不是非常之多，不是非用大型机不可，但因大型机的特殊控制单元多，可进行热备配置，因而采用了大型机。 thorn emi circuit board ao-00223d/1
