This property determines the type of writing used by an OPC UA Block Tag. If this property is set to True, this writing is synchronous, that is, the OPC UA Driver waits for the result of the writing to the server. Otherwise, this writing is asynchronous, that is, the value in the OPC UA Block Tag is sent and the processing in the OPC UA Driver continues immediately. Default value of this property is False.
NOTE |
In asynchronous mode (property disabled), communication performance tends to improve, but in synchronous mode (property enabled) the success of the writing operation is verified and informed. |
