Hi everybody out there....
Does anybody know if it is possible to call a method using an OPC-UA Client (DSC module). I have to do this, but I cannot see any methods in the browser tool although there are some implemented in the node class (server side).
Regards

Hello guys,

I have the same problem! Or does somebody know a work around to call OPC UA methods over LabVIEW?

Hello to all,
i used a workaround. I created a OPCua client and use the event subscribtion. In the event structure the method will be placed.

Hope this helps a little bit.

Did I understand that right, that you first create an Event Subscription and then add the methode to the Monitored Event Nodes? The methode will create an event if it's executable?
And how you call the methode? With the Respond Acknowledgeable Condition VI?

Hello DominikZ,
Yes you are right i created a dummy client for this and i used this architecture and placed the method in the event structure.
You have to change the subcription time. I set it too 2ms for checking the change.

Thanks a lot.
But did you use the the Respond Acknowledgeable Condition or the Enable Condition to respond (call) the method?
And if you use the Respond Acknowledgeable Condition what do you have to send as a request method? Confirm or Acknowledge
