Asyncua Server - Source TimeStamp

[marcos-schmitz]

Hello

I need some help with Asyncua Server. How do I make it update the value of the Source TimeStamp when some value is changed in UA Expert, for example?

You need to pass a DataValue which containes the Timestamps a StatusCode and the value ( Variant with value and DataType and information if it is an Array or not )

  dv = ua.DataValue(
          ua.Variant(
              100.0, 
              ua.VariantType.Double
          ),
          StatusCode_=ua.StatusCodes.Good,
          SourceTimestamp=datetime.datetime.utcnow(),
          ServerTimestamp=datetime.datetime.utcnow()
      )

Hello, thanks for the informations, but I have solved my problem with this:
Set ServerTimestamp when attributes/values are written #1135

[AndreasHeine]

ok! you asked for the sourceTimestamp!?

Yes, but I applied the same technique to update both values.
