OPC Data Access 2.0 Components

Readme File

The FactorySoft OPC Data Access Components package installs
the Server Browser, the Data Access 2.0 proxy dlls, and the 
Automation dll in the System directory. This installation 
can be freely redistributed with your products. It can be 
used to install the OPC components needed for your server. 
It can also be used on client computers that will run 
custom or automation clients.

Automation -- The Automation interface has been completely 
redesigned and implemented. The new interface is easier 
to use from Automation languages, easier to understand, 
and it is general purpose. Server vendors no longer need 
to create an automation dll for their server. FactorySoft 
wrote the Automation interface sample code for the OPC 
Foundation and we provide a standard Automation component 
based on this code for redistribution.

Server Browser -- This COM server returns OPC Servers 
by Component Category. It can be used to find Data Access 
1.0 or 2.0 servers, in addition to future OPC servers. 
Because this is a COM server that can be run remotely, 
clients can now get access to remote servers without 
local registry entries.

Please stop any OPC servers or clients running on this
computer prior to installation.
