write to opc by using datasocket

[BigBadWolf]

Hello,

I would like to create an OPC client with LabVIEW. The OPC Client should read and write variables from an OPC server. Reading the variables work. Once I want to write to one item I got the error message:

 „Fehler 1179 ist bei DataSocket: Öffnen in OPC Client.vi à BspAuftufOPCClient.vi aufgetreten

Mögliche Ursachen:

LabVIEW:  Zugriffsmodus wird für die Operation nicht unterstützt.“

Why can´t I open the DataSocket in the Modus write?

You can see my VI in the attachments.

Thanks

Volker

Hello Volker,

you access two times to the same ressource. Please control the dataflow with an error connection.
A connection from the error out (close function of the lesen vi) to the error in of the datasocket open vi (schreiben).

Kind regards,

Elmar
