300在西门子的PLC产品类里属于：中型PLC系统，适合的控制对象一般都在256点以上，1024点以下的编程软件不一样，具体编程语言编程思路都不一样！
1、S7-200系列用的STEP7-Micro/WIN软件；S7-300使用的是STEP7软件。
2、S7-200系列的编程语言有三种：语句表（STL）、梯形图（LAD）、功能块图（FBD）；S7-300系列的除了这三种外，还有结构化控制语言（SCL）和图形语言（S7 graph），其中SCL就是一种高级语言，高级语言可以更加方便的解决客户的专有问题，提高了程序执行效率，缩短了程序执行时间。
3、S7-300软件的特点就是提供了一些数据块来对应每一个功能块（Function Block-FB），称之为Instance。S7-300不能随意的自定义Organization Block、sub-routine和Interrupt routine，系统只能调用它OB1，其它的用FB－Function Block和FC－Function方式编辑，其它的也是预定义成了系统的了，System的S给它们（SFB、SFC）定义了自己的身份。
