OPC Data Access Automation Objects & Interfaces  

4.1

 

OPCServer Object 

Description 

A client creates the OPCServer Automation object. The client then 'connects' it to an OPC Data 

Access Custom Interface (see the 'Connect' method). The OPCServer object can now be used to 

obtain general information about an OPC server and to create and manipulate the collection of 

OPCGroup objects.' 

Syntax OPCServer 

Remarks 

The WithEvents syntax enables the object to support the declared events for the particular object.  

For the OPCServer, the only event defined is the ServerShutDown. The OPCGroup (described 

later) has all the events associated with DataChange and the events as required to support the 

Asynchronous methods of the OPCGroup object. 

Example 

Dim WithEvents AnOPCServer As OPCServer  

Set AnOPCServer = New OPCServer
