如何将PLC连接到c# 2.0

如何将Sigma PLC连接到c#

我有BaudRate, Parity, StopBits和DataBits。

和写入/发送数据从c#到PLC。

System.IO.Ports.SerialPort por = new System.IO.Ports.SerialPort();
private void Form_Load(object sender, EventArgs e)
{
     por.BaudRate = 9600;
     por.Parity = None;
     por.StopBits = 1;
     por.DataBits = 8;
     por.DataReceived += new SerialDataReceivedEventHandler(por_DataReceived);
     por.Open();
}
