I should also point out it is forum etiquette to state and link if a question is a cross-post on Ni.com. https://forums.ni.com/t5/Industrial-Communications/NI-9145-with-NI-9476-9375-in-TwinCAT/td-p/4485626

IIRC. There is a safe-mode that will set outputs to a safe value (presumably 0v for sourcing 24v) when active. However. I think the status LED of the controller should be blinking red to signify that. Apart from that. If a variable can be set but it's not being replicated in the slave device (the NI device is a slave, right?) then it points to a mismatch in the PDO mapping. I do not know how you would tell that from the XML files you supplied but you may know more about their construction than I.

Mailing lists were great for maintainers, horrendous for users. Waiting a week to see if your question was answered and trawling through the archives in case you missed a response. One's issue getting engulfed in spam of the same simple issues posted by different people over and over again. I'm glad the days of IRC, Mailing Lists and, hopefully, Discord, are way behind us. Even SQLite eventually dumped the mailing list and support has greatly improved because of it.

Discord is a poor support platform and I view Discord with the same contempt as IRC (and for similar reasons). If one thinks Lavag.org is a sub-optimal platform with little activity; answer the question or suggest posting the same question on NI.com. EtherCAT is a niche expertise and if you can't find help here or on NI.com, I very much doubt you will find it on your Discord server.

Unlikely.

Lots of exclamation points against using Bytes At Serial Port and then goes on to use Bytes At Serial Port More seriously though. You avoid a lot of the problems if you just pop up on the read prototype and set it to Synchronous IO mode instead of Asynchronous.

I don't have an Arduino to hand but here is a quick and dirty conversion of your dump file so you can see how it would be done. Not much in the JPG to look at though str2jpg.zip

Why is the XKCD mage URL (for hotlinking/embedding) blocked for posting? -> "The link could not be embedded because that URL is not allowed."

I see that as a testament to quality. No contact, no bugs.

I think the main issue (and probably the reason for the question originally) is the Cyber Resilience Act which basically makes everybody legally responsible for software they use. There are carve-outs for opensource but the only real way forward is through what they call "Software Stewards". I wouldn't stick your head above the parapet for OpenG. The next question will be "where's the SBOM and CVD Policy" The way forward would be for NI or JKI to name themselves as "Software Stewards" for OpenG but it's a big ask for American companies.

Me too, for the compane. I got fed up with deleting connectors every time I created a new VI.

Can I Use LabVIEW on My Linux Machine with an ARM Processor?

No. I'm saying *if* the device is hardware independent then it wouldn't matter if a CSZ and/or Enviro device was installed and deployment of the hardware driver could be based on the platform, not the device. Rolf solved that by abstracting through VISA. However, you stipulated that you can't have both (CSZ & Enviro) classes in memory.

I wrote a markup string xcontrol. I really should look at it again because I don't think the mouse-over for links work properly on Windows 11.

Then you added not in memory for deployment to platforms. That's what messes the straight forward choice up because the platform hardware isn't abstracted.
