My answer is:

Yes it is possible, CIT made it easier for you to implement  the communication layer.

You could use a PROFIBUS interface to bring data into LabVIEW.  NI sells PROFIBUS cards in both PCI and PXI form factors which include an API for communicating with the instrument inside of LabVIEW.
