Hi Richard,
Need more information about your setup. What kind of EPICS server are you using ?

As pppl mentioned, NI is working on a piece of software that will allow a LabVIEW Windows application to be an EPICS client. This is implemented as a plug-in for the LabVIEW shared variable. The plug-in allows a LabVIEW for Windows application to read and write variables on the network using EPICS Channel Access Protocol. At this point, we cannot host an EPICS database - just be a client in the system. We are calling this the LabVIEW EPICS Client I/O Server ("I/O Server" is the LabVIEW name for these types of plug-ins).
Using LabVIEW shared variables, you can get a LabVIEW Real-Time node (i.e. CompactRIO system) to participate in the EPICS system; however, it will need to communicate through a LabVIEW Windows node. You can think of the LabVIEW Windows node as "translating" channel access protocol to LabVIEW shared variable protocol. The attached powerpoint file gives you a visual of how this works (slide 8).
The LabVIEW EPICS Client I/O Server requires LabVIEW and LabVIEW DSC (Datalogging and Supervisory Control) Module, version 8.0 or 8.20. If you (or anyone else) would like to download this EPICS client software, you just need to sign up for the LabVIEW DSC beta program online at: www.ni.com/beta. You can list my name as the referring party.
We would definitely appreciate any feedback you have about the software and/or your particular use case. Feel free to contact me (product strategy) or Arun Veeramani (product marketing) directly at:
