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.
I suggest to compare Modbus packets sent by Rapid SCADA and the other software.

The oldest I have are
OPC Core Components Redistributable (x64) 105.1
OPC Core Components Redistributable (x86) 105.1

Hello,

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.

[Mikhail]

Hi,

Please provide screenshots of the settings and error.

[Mikhail]

Did you install OPC Core Components?

[Mikhail]

The 1st link does not work.

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.
