第1段密就和FX2N的一样，加的是明码，第2段就不一样了，密码加上后都变了，算法也完全变了，但在网上有高手能做到直读密码，我们被FX3U这种PLC的强大功能所吸引，对三菱PLC大家都用习惯了，觉的用起来顺手，在整个工控行业中用的比例很大，所以对破解这款PLC产生的浓厚的性趣， FX3U有的可以2个口编程，一个是我们通常用的圆口，还有个可以扩展个232接口，我先试圆口，通过串口软件监控的数椐，以下是我调试监控的数据。

6、上述 从串口监控到的数据是十六进制的数据，还真不好看，先转换成ASC码，就好看多了。

电脑发：00E0202 ’查询D8001的值
PLC回：B15E ‘回复为5EB1，回复的数据高位在后、低位在前，所以要对调个位，
5EB1转为10进数据值为：24241，24表示PLC型号FX2N或3U，241表示版本号，
电脑发：00ECA02码 ’查询D8101的值
PLC回：713F ‘回复为3F71转为10进数据值为：16241，16表示PLC型号为FX3U，241表示版本号
以上这一大段数据也就是编程软件查询一下PLC的型号，以便接下来按相应的通迅协议进行通迅。这些数据是花了大量时间测试出来的，
这次就讲到这里，望朋友多多指点。
