First, you should probably look for examples. There are lots of Excel
examples that ship with LV and available from the ftp/web site. These
will not specifically help with your control, but they will show how to
use ActiveX nodes with an Automation Server Interface. The next thing
to do is to gain acces
s to your Profibus object. It may really be a
control, in which case you drop an OLE/ActiveX Container on the panel,
popup and insert your control. The terminal of this control is the
refnum for the Automation interface, and you can immediately start
setting/getting properties or invoking methods. Most likely, the object
isn't a control, but a server, then the only thing that changes is that
you will need to use the Open node to get a refnum, and you can do
properties and methods on that.
