可编程控制器类型

4.1按控制规模分

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，如德维森公司的V80系列PLC本体从16点到40点，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。如如德维森公司的V80系列PLC可扩展到256点，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。如德维森公司的PPC11系列可扩展到1024点，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。如如德维森公司的PPC22系列可扩展到2048点，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*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。

4.2按结构划分

PLC可分为箱体式及模块式两大类。微型机、小型机多为箱体式的，但从发展趋势看，小型机也逐渐发展成模块式的了。如OMRON公司，原来小型机都是箱体式，现在的CQM1则为模块式的。

箱体的PLC把电源、CPU、内存、I/O系统都集成在一个小箱体内。一个主机箱体就是一台完整的PLC，就可用以实现控制。控制点数不符需要，可再接扩展箱体，由主箱体及若干扩展箱体组成较大的系统，以实现对较多点数的控制。

模块式的PLC是按功能分成若干模块，如CPU模块、输入模块、输出模块、电源模块等等。大型机的模块功能更单一一些，因而模块的种类也相对多些。这也可说是趋势。目前一些中型机，其模块的功能也趋于单一，种类也在增乡。如同样OMRON公司C20系列PLC，H机的CPU单元就含有电源，而Ha机则把电源分出，有单独的电源模块。

模块功能更单一、品种更多，可便于系统配置，使PLC更能物尽其用，达到更高的使用效益。
