BACnet/IP之BACnet4j学习java代码例子属性读写同网段跨主机02

    上一篇博客中https://blog.csdn.net/dream_broken/article/details/106646604，代码和设备模拟器Yabe是同一台电脑上，现在试试代码和设备模拟器不在同一台电脑上，但是在同网段内，因为bacnet ip是通过udp在同网段内进行广播的。现在进行测试下。

   Yabe运行在192.168.0.200上，代码在192.168.0.123上。

  执行结果就不贴了，能正常读取到192.168.0.200上Yabe的数据。更改设备端数据也是一样可以的，就不贴代码了，参考上一篇博文。
