Abstract:

         We implement serial communications between PC and DVP Series PLC in the control system of a completely automatic tester with the internal SerialPort class of C# and .NET based C#. This can increase the flexibility of serial communications program design and the reliability of data transmission through serial ports. Application results show that the transmitted data is accurate and reliable and the program runs stably.

Key words: .NET, completely automatic tester, PLC, communications protocol
