Not used labview, but on Kepware you can configure the tags on the kepware i.e. device1.Channel1 then a name "register_1" then the address (for ex if it was mitsi it would be D0001).

then if labview is a good bit of software you could browse the opc server & import the tags.

Kep doesn't require you to fill in the tags, instead you can create the tags in labview & providing you have the correct settings/opc link it should work.
best thing to do is set up opc comms, configure a tag in your opc
then use an opc client (some opc servers come with one for testing).
it should tell you if comms are working.
No knowing what plc/opc server you are using I cannot help anty further.

Willem,
If you have plain LabVIEW 8 (without LabVIEW's DSC module) you'll be using Datasocket to connect to your OPC server. Datasocket/OPC connections can be done either by:
1) simple linking/binding of front panel controls/indicators to OPC server items; or
2) coding on the block diagram using Datasocket VI's.

There are examples of 2) which ship with LabVIEW. Search for OPC or Datasocket using LabVIEW's example finder.

There are discussions of 1) on NatlInstruments website e.g.
