Datalogger view does not log when Source Timestamp changes

Dear Support Team,
We have our OPC UA server does firing of datachange event based on Value or Quality or Source Timestamp changes.
The data logger view in UaExpert logs data when there is value of item changes.
It does not log the data when the Source Timestamp of item alone changes ( i.e Value and Quality do not change; only Source Timestamp changes )

Do we have any option in UaExpert to log the data when the Source Timestamp of the item alone changes?

Thanks
Antoni

Hello,

Currently there is no way of setting the DataChangeFilter of the MonitoredItems being created. We will add this to our list of feature requests for UaExpert.

Best regards
Support Team

Source timestamp is not reflecting in Data access view

Dear support team,
I am getting the data from a DB and assigned with the source timestamp. When it is connected with UA expert tool, this assigned source timestamp is coming in the attribute window . When the data is updating, the client tool is taking the local system time, instead of assigned source timestamp. Please help me if I need to change any settings in UA expert tool to reflect the source timestamp
Thank you

Hi,

the timestamps in OPC UA are always UTC.

It is the client-side decision how to display the timestamps, many do convert into their local time zone, to make the time stamps more "easy" to read/interpret by the user. The UaExpert (client) has decided to use local time when storing in Datalogger CSV file, because the local client side CSV storage is considered local time zone. The UaExpert has no option to configure/select the timestamp used when writing to local file.
