两种机型PLC在交通灯控制系统中的编程比较

Programming Comparison About Two Kinds Of PLC In The Control System Of Signal

以交通灯控制系统为例,探讨了德国西门子PLCS7-200机型和日本松下PLCFP1机型在编程上的区别和联系。通过具体编程比较得出结论:两种机型PLC虽然编程符号不尽相同,可是编程思路和方法是相似的。

To traffic light control system, for example, discusses the German Siemens PLC S7-200 models and Japan＇s Matsushita PLC FP1 models on the difference in the programming and linkages. Comparison concluded that the adoption of specific program： two kinds of models PLC programming while not exactly the same symbols, but the programming ideas and methods are similar.
