PLC传送带设计

Question

A，B，C三条传输皮带，分别受M1，M2，M3三个电动机拖动,是此三条传输皮带运转的时序图。编写一个用PLC控制它们运转的梯形图程序。要求它们按A－B－C顺序启动，而后按C－B－A的顺序停止。
注意：要求用西门子PLC控制系统实现

Answer 1

用顺序功能图编写的，你可以把下面的程序复制到编程软件里，查看方式为STL,然后转换成梯形图程序，再用S7-200仿真看一下就OK了，谢谢！

发个4条传送带的你看下本回答被网友采纳

Answer 3

你用顺序功能图写这个程序啊，用经验法写太多了！写顺序功能图挺简单的，就是按题目条件写下来，再把它翻译成梯形图啊！感觉前面人回答的语句表程序太多了，有点麻烦！

Answer 4

你要先了解到底怎么控制电机联动，比如，是一起动还是传送带上传送个物品A-B-C等，外围的检测，和PLC I/O点的定义，了解明白，你在提问题，要不，谁都帮不了你
