S7-200虽然应用广泛，但毕竟是落在时代背后一大截了。基础篇，流行的教材中以廖常初的为流行和通顺，正好他也是主要教西门子系列的（不确定是不是有1200系列的教材，我猜应该是有的。至少他的200和300系列的书都不错）。要了解PLC的基本结构，但是不要在这方面太过执着，适可而止的了解，或者说是基本了解、一知半解即可。在以后的应用中有足够时间可以深入了解；深入了解LAD梯形图的画法，对基本概念比如线圈、节点、计数器、定时器、移位、比较、计算、上升沿下降沿等等，务必要熟练掌握；对于其他类型的编程语言，如果有可能，能学习了解一下，比如STL或者FBD，这些并不是华而不实的炫技，而是一方面能加深对PLC的理解，第二能方便快速实现某些功能，第三能够很好的与**文本语言相辅相成互相促进。
