RE: EPICS Support for NI-9223

[Freddie Akeroyd - STFC UKRI via Tech-talk <tech-talk at aps.anl.gov>]

Hi Abdalla,

 

The module just depends on the NI DAQmx library and EPICS asyn, the link you mention below should give you the necessary DAQmx C library to use. We have only ever used this on Windows ourselves, we do have a linux RHEL9 build server but I notice we currently exclude building this module there at the moment. I can give building it there a go and also tidy up our support module a bit as I think it looks to include some unnecessary other parts of our system, I can probably get that done by sometime tomorrow inbetween other things I am doing

 

Regards,

 

Freddie

Hi Freddie

 

Thanks for the link, I am not familiar with NI ecosystem so I have few questions:

1. Any prerequisites for building this support?
2. In this downloads page https://www.ni.com/en/support/downloads/drivers/download.ni-daq-mx.html#565431 there is a section for Linux downloads, does this download provides an API that I can use to build an EPICS driver on Linux or is it Just a LabVIEW instrument driver?

 

Thanks!

Hi Abdalla,

 

We made a fork of the original EPICS DAQmxBase software and adapted it for DAQmx on Windows – the code is at https://github.com/ISISComputingGroup/EPICS-DAQmxBase

Freddie

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,
~Ralph
