推荐这款可网络控制的继电器，16路继电器，16路IN，折腾了好几天在几位同事的帮助下终于把IOC调通了。基本的通过PV控制继电器的开关都调试成功，点控还没做，以后有空再做吧，如果看到的愿意做的可以继续做下去，不过labview程序把点控做好了，欢迎去下载：
https://gitee.com/lup9304/tuning-tools/blob/master/netio1.0.llb
这东西用起来很方便，比plc、西门子模块等方式搭建IO控制省事多了，一般的使用足够了，如果大电流大功率使用，可以自己外加继电器，用这个网络继电器控制外加的继电器即可。
具体怎么编译IOC，可以参看下面链接：
https://epics.anl.gov/modules/soft/asyn/R4-24/HowToDoSerial/HowToDoSerial_StreamDevice.html
需要socket通信，在上面链接里加dbd这一步时：HPE3631Atest_DBD += drvAsynSerialPort.dbd，换成：drvAsynIPPort.dbd就好了。
之后就是编写db、proto、st.cmd文件了。附上相关的文件，写的很不专业，欢迎大家下载使用并请修改的更简洁：
