Has anyone else experienced an issue with the opc server failing to poll over time? My application will work fine for a few hours then it just quits updating. The device status shows a few read errors but the just quits scanning. desabiling and renabling device scan does nothing. I shutdown the runtime and restart it and all is back to normal till it does it again in a few hours.

FYI, Problem turned out to be the OPC DA Server was 3.0, and Winlog is only compatible with 2.0 and older. I hope there is plans in the future to bring Winlog's OPC compatibility up to 3.0 as many OPC DA Servers are no longer backwards compatible.
