I’ve changed condition in DevOpcClassicLogic.cs from

/// <summary>
/// Gets the tag status corresponding to the item quality.
/// </summary>
private static int GetTagStatus(Opc.Da.ItemValueResult itemValue)
{
 return itemValue.QualitySpecified && itemValue.Quality.QualityBits == Opc.Da.qualityBits.good ?
 CnlStatusID.Defined : CnlStatusID.Undefined;
}

to

private static int GetTagStatus(Opc.Da.ItemValueResult itemValue)
{
 return itemValue.QualitySpecified && itemValue.Quality.QualityBits == Opc.Da.qualityBits.good || itemValue.QualitySpecified && itemValue.Quality.QualityBits == Opc.Da.qualityBits.uncertain ?
 CnlStatusID.Defined : CnlStatusID.Undefined;
}

Then I’ve compiled DrvOpcClassic.Logic.csproj and swapped the driver logic DLL. Now “uncertain” tags are showing in OPC UA. Hope this is a somewhat safe change.
Thanks a lot for the help!

Ok, I’ve compiled everything using those DLLs

So, I’ve built everything. The only problem was that my NuGet couldn’t find
<PackageReference Include=”OpcComRcw” Version=”2.1.108″ />
<PackageReference Include=”OpcNetApi” Version=”2.1.108″ />
<PackageReference Include=”OpcNetApi.Com” Version=”2.1.108″ />
and I had to use “Quick.” version of these packages

As far as I know, this is an expected behavior for tags in manual mode.
Anyways, do you mind sharing a guide or a link for the already existing solution on how to compile a new driver with this bypass?

Thank you for your answer, Mikhail. Is there any way to bypass this?
