LabVIEW is widely used for experimental station control in SPring-8. LabVIEW is also partially used for accelerator control, while most software of the SPring-8 accelerator and beamline control are built on MADOCA control framework. As synchrotron radiation experiments advances, there is requirement of complex data exchange between MADOCA and LabVIEW control systems which was not realized. We have developed next generation MADOCA called MADOCA II, as reported in this ICALEPCS (T.Matsumoto et.al.). We ported MADOCA II framework to Windows and we developed MADOCA II interface for LabVIEW. Using the interface, variable length data can be exchanged between MADOCA and LabVIEW based softwares. As a first application, we developed a readout system for an electron beam position monitor with NI's PCI-5922 digitizers. A client software sends a message to a remote LabVIEW based digitizer readout software via the MADOCA II midlleware and the readout system sends back waveform data to the client. We plan to apply the interface various accelerator and synchrotron radiation experiment controls.
