PLC编写气缸往返运动调试

1、用西门子S7-200CPU224要求：A 往返10次，B 往返1次蜂鸣停机。其中开始和停止不影响计数。错误时要蜂鸣，必须摁下复位后在摁下开始才有效，不摁下复位，即使摁下开始也无效。 复位开始后，系统会再次检测错误是否改正，改正则接下去运行，否则继续蜂鸣报错。 急停按钮摁下，不管摁任何键都无效。复位2秒后，计数器清零气缸回复。2006版CAD 图：图1： 图2 图3 图4 图5 PLC 程序：TITLE=程序注释 Network 1LD I0.0O M1.0A I0.2A M0.0= M1.0Network 2 / 初始化阶段 / 网络注释LDW= VW0, 0 LPSA I0.1TON T37
