Tag Overlay Timing

We have a source of data that is OPC-DA and is sometimes stable, sometimes not.

The main issue we’d like to fix is that when it goes out momentarily we get a tag overlay but then it comes back and the tag overlay disappears. There is nothing we can do about this in terms of fixing the source of the issue but we want to improve the visuals.

Is there a way that we can delay the tag overlay to happen later (say 5 seconds) so that we don’t get tag overlays when there are only brief issues?



I think this is handled by the stale timeout period. Look for it either in the tag group settings or the opc-da config

@nminchin Looking in the tag group settings and the OPC-DA connection setting I’m not seeing any setting for stale timeout period. What am I missing?
