Hello,
If channel 101 has length = 3, there are shadow channels 102 and 103 are created by Server.
You should not use channel numbers 102 and 103 explicitly in the Channels table.

Hello,
Your description is correct.

OPC Core Components Redistributable (x64) 105.1

Hi,
Try setting channel’s Data Length to 3, for example. Note that next 2 channels may not sequential channel numbers.
Each 1 of data length may contain up to 4 Unicode characters.

Please provide screenshots of the settings and error.

Data type = Unicode string
Format = String
Output formula = SetUnicode()

[Mikhail]

Hello,
You should add the SetUnicode function into the Scripts table. Then use it in the channel’s formula field.
If you provide screenshots of your settings, I can check.

Channel should be of the Calculated/output type

[Mikhail]

Hello,

Try

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;
}
