Hi Barry,
unfortunately the update mechanism is not always stable. We could so far not figure out what we are doing wrong here. So what you are doing is totally right.
What you can try to fix it is to remove the update site from the available software site. You can do this by going to Window->Preferences-> Install/Update->Available Software Sites
There remove everything, add a new update site: https://download.eclipse.org/4diac/updates/latest
Close 4diac IDE, restart it and then check for updates from the help menu. I hope this fixes your update problem.

Definitely - we would enjoy writing a blog post. I would be happy to submit a draft to you of the blog entry for the news section. Is a Word-format document OK?
The avionics project is an exploration of how feasible it is to create IEC 61499 applications with 4diac that could satisfy the D0-178C Safety-Critical Airworthiness criteria. That will end up as a journal article next year, but an early news blog post would be an ideal way to publicize the work in-advance.
We also have a small tutorial Fan and I have been writing for students in our lab. It details how to build a simple Alarm Clock app in 4diac. Just two function blocks but it is designed to walk through the whole process from creating a custom block, using library blocks, through the configuration of the CMake, compiling and then deployment and debugging. It is designed to complement the examples on the current 4diac site like the LED Flasher, etc.

Thanks a lot. This would be great. Word is fine. I would turn this into the html/php needed for the web page. But if you like the web-page is in git you can also directly add there and push it to our gerrit review system.
Also the other topics are very interesting. I'm thinking how we could make other people aware of your tutorials (if that is ok for you). Maybe a link collection page or something would be nice.
BTW we are also collected papers people have written using eclipse 4diac. Our vision is something like a 4diac use in research page with paper references and links to them. What do you think?

Thanks Alois,
That is interesting. Post-Doctoral, I am concentrating on IEC 61499 applications with an emphasis on machine control. So, lots of work on sensors and actuator control. As part of my thesis, I created a Heating Ventilation and Air-Conditioning Room Controller in 4diac and got it running on a Pi. That opened up a lot of work on Linux sensor drivers. I have a rough tutorial draft that I need to polish that shows how to control a DS18B20 temperature sensor with 4diac. That could be useful for anyone beginning to use IX/QX function blocks on a Pi. Using a sensor with a well-developed Linux driver (mounted with modprobe) makes the integration with the SIFBs a lot easier since the algorithms simply become reads of the symbolic link files the sensor controls.
Fan and I will tidy up those documents and get them to you after Christmas.
Have a great holiday break.
