Hi, @engycz
Please, review my code at OPC306, I wonder, how to set tag quality and timestamp? By default tag_quality is OPC_QUALITY_GOOD and tag_timestamp is just current system time. But, I'd like to:
type
TTag = class
Value: variant;
Quality: word;
dateTime: TDateTime;
end;
...
Tag: TTag;the dictionary. }
TagList := TDictionary<String, TTag>.Create;
Tag := TTag.Create;
{ Add some key-value pairs to the dictionary. }
Tag.Quality := OPC_QUALITY_BAD;
Tag.Value := 0;
Tag.dateTime := now();
Dictionary.Add('FSO.Drum.Drum1.T_Burner', Tag);
but I can not init tags and so on ...
It would be great to be able to use this excellent OPC library in something newer than D6 (latest mentioned in the docs) or D7 (where I have successfully got it working).
I've had no success in current Delphi versions, nor in Lazarus (FreePascal). It's a long shot but has anyone else tried/succeeded with this?
What steps will reproduce the problem?
1. Compile Example1 (from prOpc_r52.zip)
2. Press [Connect], then [Browse]
3. Select some node.
What is the expected output? What do you see instead?
Expected: no error, display node info.
Actually: info displayed, error occurs.
What version of the product are you using? On what operating system?
prOpc_r52.zip, Windows XP SP3
