Read-and-write property controlling the behavior of sending a value in writing operations. This property must be configured according to the OPC UA server in use, otherwise this writing fails. Possible values for this property are the following:
•0 - wvmDefault: Follows the default behavior of the OPC UA Driver to write only the value
•1 - wvmValueOnly: Writes only the value (default)
•2 - wvmValueQualityTimestamp: Always sends the quality and the time stamp together with the value
This property cannot be changed while communication is active.
NOTE |
Using the value 2 - wvmValueQualityTimestamp affects the way values are sent to an OPC UA server, regardless of the way a writing is triggered by E3. |
