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