手机端ModbusTcp主站工具及程序-创新互联

Modbus协议在工业现场使用比较频繁，为方便手机调试，在android上做了个ModbusTcp主站功能。

1：使用说明
作为主站，需要连接从站，因此需要配置从站IP、端口以及协议中从站地址。
连接成功后这些配置就不能修改。
偏移是需要读取或者写入的起始地址。
长度读取或者写入的总长度。
后边的长度按键是，为写入准备输入数据区数据。一般步骤先设定需要写入的长度，当然根据实际情况可以同时设置偏移量；在点击长度，就会在写入区生成需要写入长度项目，然后设定需要写入的值。

读取按键，按设定的地址和长度以及功能读取器从站数据，读回来的数据，如果是是3、4功能号的，选择了十六进制，就按十六进制展示；否则按十进制展示。
写入按键，从偏移量作为基地址写入从站。
清理按键是清理写入区内输入的内容，清理不会写入到从站。
“----->”传递按键，在有些情况下，可以直接把读取的实际传递到写入区，然后修改部分数据后，直接写入到从站。这样就不需要逐条输入，方便操作。
2：程序说明
页面上在读取展示区和写入输入区是两个ListView组件。读区的item是两个TextView，写入输入区是一个TextView和一个EditText。
ModbusTcp功能直接使用的是Modbus4Android的jar包。核心功能代码如下

读函数把成功和失败都用广播播放出去。
写只把失败广播出去。
3：测试效果
程序功能基本满足现场测试需要，方便随时联调。在测试过程中出现程序闪退，经跟踪，闪退异常原因“java.lang.IndexOutOfBoundsException: Index: 99, Size: 10”，是ListView的adapter在更新数据时，老数据操作未完成引起。经修改程序后，未出现闪退情况。
