(Not recommended) Graphically browse OPC DA server name space

Support for the OPC Data Access (DA) standard will be removed in a future release. Instead use OPC Unified Architecture (UA). See Compatibility Considerations.



ItmList = browsenamespace(DaObj) opens a graphical name space browser for the OPC Data Access Client object DaObj. The graphical interface lets you construct a list of items and return a list of those fully qualified item IDs to ItmList. You can use ItmList to add items to a Group object using additem. The name space is retrieved from the server incrementally, as needed.

ItmList = browsenamespace(DaObj,ItmListInit) lets you specify an initial list of item IDs to augment.

ItmList = browsenamespace(DaObj,ItmListInit,true) loads the entire name space into the dialog box.
