The data type of the output channel is ASCII string, how to modify the string through send command.

You need to process CmdDataStr in the output formula

[Mikhail]

Add the following function in the Scripts table:

public byte[] SetStr()
{
  string s;

  if (CmdData == null)
    s = "null";
  else 
    s = Encoding.UTF8.GetString(CmdData);

  SetData(CnlNum, EncodeAscii(s), 1);
  return CmdData;
}

Set the output formula of the channel to SetStr()
It works for a channel of the data length = 1 (or empty)

length of string is great than 24

[Mikhail]

The function below takes a data length into account for Unicode strings.

public byte[] SetUnicode()
{
  if (ArrIdx == 0)
  {
    string s = CmdData == null ? "null" : Encoding.UTF8.GetString(CmdData);
    int dataSize = Channel.DataLen ?? 1;

    for (int i = 0; i < dataSize; i++)
    {
      string part = Substring(s, i * 4, 4);
      SetData(CnlNum + i, EncodeUnicode(part), 1);
    }
  }

  return CmdData;
}
