一）实训项目工艺要求：采用S7-300设计一个自动洗衣机控制系统，具体控制要求如下：
1.水位选择：按动按钮WS1次，水位选择为低，L0灯亮，再按动1次，水位选择为中，MI灯亮，再按动1次，水位选择为高，则HI灯亮，若继续按动，则选择为低水位，如此循环。
2.水位选择好后，按下启动按钮ST，1秒后进水电磁阀V1动作，水位上升（用电位计模拟水位，用模拟量输入模块采集水位信号）；到设定水位（低水位2v，中水位4v，高水位6v）后，进水阀关闭，2秒后，开始洗涤。
3.洗涤时，正转30秒，正转洗涤指示灯FW亮，再停两秒，FW灯灭；然后反转30秒，反转洗涤指示灯RW亮，再停2秒。
4.如此循环5次，打开排水阀V2。排空（电位计输出为0v）后，开始脱水，脱水灯DE闪亮，30秒后脱水结束；DE灯熄灭。
5.开始清洗，重复2-4步骤，清洗2遍。
6.清洗完成，报警AL，3秒后自动停机。
7.若中途按下停止按钮SP，所有阀门、电机都处于停止状态。可进行手动排水和脱水：合上S1，排水阀打开，水排空后停止；合上S2，手动脱水，脱水灯DE闪亮20s后熄灭。-Technical requirements of training project: S7-300 design of an automatic washing machine control system, the specific control requirements are as follows:
1. Water level options: press the button WS1, water level selection for low, l0 lights, to press 1, level selection, MI lights, to press 1. To the water level is high, is hi lights, if press, low water, and so on.
2. The water level after selecting, press the start button st, 1 second after a water inlet electromagnetic valve V1 action, water level rise (potentiometers for use in simulated water level, with analog input module level acquisition signal) to set water level (low level 2V, water level in 4V, the high level of 6V), the water inlet valve is closed, the 2 seconds later and began washing.
3 washing time, is to turn 30 seconds, is turning washing indicator light FW, and then stopped two seconds, FW lights out and then reverse 30 seconds, reverse wash indicator RW light, and then stopped 2 seconds.
4 so loop 5 times,
