B - 18 RSLinx – Training Guide
NOTE: the issue under discussion here is Server Browsing. This is entirely different from
the Address Space browsing discussed in the OPC Data Access Interface.
Overview of the Solution
The OPC Foundation supplied Server Browser OPCENUM.EXE can reside on any
machine, will access the local Component Categories Manger and provides a new interface
IOPCServerList which can be marshaled and used by remote clients. This server has a
published classid (see below) and can be installed once on any machine which hosts OPC
servers. The client still needs to know the nodename of the target machine however he can
now create this object remotely and use it's IOPCServerList interface to determine what
types and brands of servers are available on that machine.
