西门子s7-1200系列PLC可以通过添加全系列通用的信号模块、通信模块和信号板来满足各种不同的设计需求。CPU和模块的型号较多,查阅动辄几千页的手册确实比较费时间,故将常用的接线图进行汇总以备后用。
S7-1200系列目前共有5种CPU类型:CPU 1211C、CPU 1212C、CPU 1214C、CPU 1215C、CPU 1217C,和3种故障安全CPU类型:CPU 1212FC、CPU 1214FC、CPU 1215FC。除CPU 1217C只有DC/DC/DC一种之外,其他型号均有AC/DC/Relay、DC/DC/Relay、DC/DC/DC三种(故障安全CPU不支持交流输入)。

CPU模块电源输入分交流直流两种;开关量输入只有24v直流(源型输入与漏型输入按实际需求接);开关量输出分晶体管输出和继电器输出两种。不同型号CPU只是点数上的区别,接法大致一样,此处以CPU 1215C系列代表。
