Remote property: start type reado edge value issue on server restart

I am reading several read only properties from a kepware opc server and I have them configured to read from the edge on start. Whenever I reset the thing it works fine but it fails to read them on server reset. Is that working as intended? And if so how can I read the edge values on server restart?

 

Thank you

No it does not work as expected - it is described in the ThingWorx release notes under known issues (TW-78472).

 

The connection between ThingWorx and Kepware has been rearchitected and the fix versions are forthcoming.  Once released, you will need to upgrade both ThingWorx and Kepware and then the issue should be gone.

 

The problem is that it connects, sees the property configuration set to read from edge on start, however is not yet subscribed to the property so cannot read it.  Until the issues is addressed, you should not use "Read from Edge" as this can cause a race condition which can potentially lead to no data coming into the property.
