Items can be accessed by their name without first creating a group. OPC DA V3 defines a similar function but the SyncIOGroup methods are implemented to work with V1,V2 and V3 servers. The class opens it's OPC group and adds items automatically at the first read or write function.
The class is designed for the simple handling of individual items. The OpcGroup class is more efficient for handling multiple items, especially large number of items.
