I noticed on the NI section of EPICS manufacturers page https://epics.anl.gov/modules/manufacturer.php#National%20Instruments there is an EPICS driver for the NI-DAQmx interface which, according to NI website, works with the NI-9223 but the SVN URL ( http://epics.svn.sourceforge.net/viewvc/epics/applications/trunk/DAQmxBase/ ) is not working. Is there another URL to clone the driver? Will this driver work with the NI-9223? Are there other alternatives?

FWIW, the modules database has moved to https://epics-controls.org/resources-and-support/modules/ a few years ago.

Note that DAQmx and DAQmx Base are two different NI software products. DAQmx Base development was frozen by NI in 2019 (last release: 2015).

ITER has plain EPICS support and an NDSv3 device driver for the IRIO library (by the I2A2 institute of UPM - University of Madrid) on top of the NI DAQmx open source driver (yet another NI driver). [1]

The first official release of the IRIO-based stack was also announced on Tech-Talk [2] and later reported in the EPICS Collaboration Meeting in June 2019. [3]

NDSv3 is the C++ framework for data acquisition that ITER proposes for its diagnostics use cases. It was presented in more detail at the ICALEPCS 2021. [4]

We're currently in the middle of the procedure to make the ITER developments for NDSv3 public. Once we have the authorization, things will appear on GitHub.

Cheers,
