C#与三菱FX5U、Q系列PLC通讯程序基于3E帧SLMP/MC协议
C#与三菱FX5U、Q系列PLC通讯程序基于3E帧SLMP/MC协议
1.最近项目需要用到C#与FX5U的PLC以太网通讯，通过研究三菱FX5U和Q系列PLC的SLMP/MC协议，使用C#语言发送报文与PLC通讯，用了一个星期时间，做了一个测试程序，封装了一个类库可以实现PLC不同变量和类型的读写，并且支持数组类型批量读写操作。
2.程序可以实时监控网络状态，具有断网重连功能。并举例采集实时曲线，测试运行稳定。
3.具体程序界面如下。下面有部分源码，需要全套源码+V：1357448516 或者 qq：584472557
3.FX5UPLC需要设置SLMP和IP地址，步骤如下。
4.设置SLMP的端口号，PLC设置完成。
