C# Modbus_TCP通訊 dll庫 測試TRIO運動控制器

在項目的實際應用中，通訊是必不可少，最近一直在測試modbus通訊，在網上找到一個合適的免費動態鏈接庫，已在項目上應用，非常穩定。

　　網站地址：www.easymodbustcp.net   

 

1、動態鏈接庫網盤地址，里面有dll文件及測試工具，例子。

　　百度雲盤：https://pan.baidu.com/s/1Uunp2CDB8Hz3uyOsWn_Umg       提取碼：dac6

 

2、下面是我以TRIO為例測試 Modbus_TCP，此外可用西門子，三菱，歐姆龍測試。

     測試截圖： 連接 ip: 192.168.0.250    prot: 502

　　　　　　

 

 　　連接成功后即可測試

　　　代碼有很多不規范的地方，由於剛剛入門C#，很多類庫第一次接觸，本想做的完善點但實屬心有余而語言不熟（正在不斷的學習中...），以上僅作參考。
