Opc data Access Automation Specification

4.1.5.3

 

Disconnect 

Description 

Disconnects from the OPC server. 

Syntax Disconnect() 

Remarks 

This allows you to disconnect from a server and then either connect to another server, or remove 

the object. It is it is good programming practice for the client application to explicitly remove the 

objects that it created (including all OPCGroup(s), and OPCItem(s) using the appropriate 

automation method. Calling this function will remove all of the groups and release all references to 

the underlying OPC Custom Server. 

Example AnOPCServer.Disconnect 

4.1.5.4

 

CreateBrowser 

Description 

Creates an OPCBrowser object 

Syntax 

CreateBrowser() As OPCBrowser 

Remarks 

The OPC Browse interface is an optional interface that is not required to be supported by an OPC 

Custom interface server.  Therefore, an OPCBrowser object will not be returned for OPC Custom 

interface servers that do not implement the browse interface. 

Example 

Dim ARealOPCServer As String 

Dim ARealOPCNodeName As String 

ARealOPCServer = “VendorX.DataAccessCustomServer” 

ARealOPCNodeName = “SomeComputerNodeName” 

AnOPCServer.Connect(ARealOPCServer, ARealOPCNodeName) 

Dim AnOPCServerBrowserObject As OPCBrowser 

Set AnOPCServerBrowserObject = AnOPCServer.CreateBrowser
