NI OPC Client status (connected?) no updating when connection is lost

[paubine]

Hi, 

I'm using DSC Module 2009 and OPCTech OPC Server.

I'm reading the value of the connection between the OPC Server and the NI OPC Client via a shared variable called "connnected?" in the NI OPC Client variable. The problem is that when I turn off the OPC Server, the value of the Shared Variable added to the project associated to the "connected?" boolean in the NI OPC Client doesn't changed to false, it stay on.

If I open NI Distributed Manager 2009 and refresh value, it then turn off. It doesn't changed by itself?

Weird thing : If I turn off the OPC Server and refresh Variable in NI Distri Manager, the boolean change to false (ok..) and the variable change back to True when the OPC Server became back on? it is working in one way....

Thanks for your help.

Patrick

What are the shared variable settings?

Could you attach a screenshot of the Varaible properties so we can see how and where you are binding the shared variable.

Here is the properties of the shared variable .

Thanks for helping.

So your binding looks good, a few other questions.

How often are you reading the Shared Varibale in your LabVIEW Application? (screenshot of the read code)

If you check the "show trend" box in DSM do you see the graph update correctly?
