Hello.
Changing the value of the tag previously developed OPC server
using the SDK Sеntrol

psstrAgent: TPsString;
psstrAgent.Value:=’TEST’;

twice ! causes a change of the tag in the server.
Change this tag using MatriconOPC Explorer occurs normally i.e. once .
What could be the reason ?

Yes, that seems to be the case indeed. For certain reasons, TPsVar.OnChanging needs to be triggered twice and it has these side-effects.

Is it a problem for you?

Yes . This causes problems. The server accept commands by writing to tag numbers. The entry in the tag new value (number of new command) causes the command to run twice. For example, double-going survey instruments that do not triples us. Please resolve this issue complicating its use. Our company is the official buyer of the library.
