First off, I am bias since I work for National Instruments.
You first need to know how you will talk to your PLC. One standard is OPC. There is also Modbus.
If you want to directly talk PROFIBUS, then you need a PCI or PXI PROFIBUS card: http://sine.ni.com/nips/cds/view/p/lang/en/nid/204268
To learn about different ways of connecting to a PLC with LabVIEW, please read: http://zone.ni.com/devzone/cda/tut/p/id/5407
You should also add the LabVIEW Datalogging Supervisory and Control module (LabVIEW DSC) to be more efficient in building your SCADA application. It is worth mentionning, that you can have unlimited Shared Variables (tags) with LabVIEW DSC. For more info on LabVIEW DSC: http://www.ni.com/labview/labviewdsc/
Contact your local NI Sales Rep for a free meeting.
