Hello @Shivam_P_Singh 

 

As you have mentioned different values , does it means the values are not what is coming from tag or some of the values are missing?

The above mentioned service Queries the value stream for the specified string property values of the Thing in a specified time range. Are you logging your property in value stream? . If yes , does all the values are missing or there are only certain historical values which are missing here?

 

Thanks

Hi @Shivam_P_Singh 

I think you checked the logged attribute for the remote bound property. With this setting, Thingworx will save property history to database and you can use query services to acquire all the VTQ change history. 

however, when Thingworx received new tag data, the new value will be queued before be saved into database by multile threads, so the update might be saved into at a different time order.

Which means it is possible for user to see partilal update history with running querystringpropertyhistory or other query services.

The only workaround is to wait several seconds till all the update saved into database.
