Hello
When i add a new OPC-Item by code, with the follow code:
Temp := TPSFloat.Create(NIL);
Temp.Name := ‘Temperature’;
Temp.OnChange := Change;
Temp.OnChanging := Changing;
Temp.OnValueChange := ValueChange;
VarIndex := OPCProvider.AddressSpace.AddVariable(RootIndex, Temp, Temp.Name);
The created Item are not showed in the Form PsVarForm where i open with the follow code:
PsVarForm.IncludeClass(TDataModule);
PsVarForm.AddComponents(Application);
PsVarForm.ConnectorBox.Hide;
PsVarForm.ReadOnly := False;
PsVarForm.Show;
How can i add the Item to the PsVarForm?
Best Regards
Gregor

The PsVarForm will find the modules that you have added to it – or in case you add Application, it will find all modules owned by Application.
Similarly, it will find the variables that are owned by the modules. So, you will need to create the Variable with an Owner module, instead of ‘nil’.
Alternatively, you can add variables and modules to the PsVarForm in code using the respective methods.
