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