Dsc - programmaticly create IO server?

Question

Is it possible to programmaticly create IO-servers in my project (I use LabView 8.0)? I can programmaticly create libraries with folders and shared variables, but I havent found a way to programmaticly create a IO-server in my project (that for ex. points to a FieldPoint OPC server)... So I wonder if this is possible at all?
Thanks in advance!

Mmmh, this is more or less a
two step process and you can't exactly do everything programmatically.
First you would need to get the DSC device registry updated for the IO
server in question. You would do this with the DSC Module VIs->DSC
Module Server Development->DSC Module Server Registration VIs. But I
have no idea if this would work with OPC too since I have only used NI
hardware or my own VI based IO servers with LabVIEW DSC until now.
These VIs are mainly meant to be used if you develop your own VI based
IO server and there is a chance that the internal database organziation
has been extended with additional attributes or tables for OPC servers,
but that those VIs do not give you access to those attributes and
tables. But I would try it out by first creating an OPC server
interactively, then using the "Get" VIs retrieve the information for
that server through those VIs to see what is what, and then try to
create my own server through the "Add" VIs of that library and see if
it works.
The next step would be to create the tags in the SCF file but as far as
I know there is no documented API access to the SCF file so this will
have to be done interactively through the Tag Configuration Editor
anyhow.
