OPC and error code 1950679030

[Dr_F]

Communication between LabView and an OPC-server only works when I run the "Distributed System Manager" at the same time. Otherwise i get the error code 1950679030.  Any hints?

Do you get this error at all times? Or, does the shared variable read correctly the first few times and then you get the error? Posting a snapshot of your code would be helpful.

The code is just for testing so far. 2 signals connected to gauges.

I get the error everytime.

If I start  the "Distributed System Manager" from the tools menu it works OK, no errors.

The OPC-server seems to work OK. I've checked this with Matrikon OPC-Explorer.

Have a look at this:

Maybe the error is associated with respect to the timing of the reads? Try to put a wait in your loop to see if you get the error?

It doesn't work even when I singel-run so I don't think it's a timing problem.
