Hi; CODESYS WebVisu is included as full version in the delivery of the BeagleBone runtime package. This means that is installed as part of your CODESYS Runtime allready. If I were you, I'd focus on building and making the visualisation for your program instead of focusing on the kiosk mode (which is trivial if you ask google); see https://support.mozilla.org/en-US/kb/firefox-enterprise-kiosk-mode or https://www.appsadmins.com/blog/chrome-kiosk-mode-introduction or https://www.jamf.com/jamf-nation/discussions/26210/ios-safari-kiosk-with-full-screen...

If you run CODESYS for BBB you won't need special software for an HMI. You can use Webvisu or TargetVisu depending on the license options that the BBB CODESYS Runtime contains. The PLC functionality is compiled, not scripted. Although special HMI software is not needed, especially when using the internal webserver for graphics(Webvisu). You could still opt to do this but it will take you way more effort. A tip is to read up on help.codeys.com on WebVisu or TargetVisu and search in the BBB runtime...

Why don't you try to read/write into your localhost pi using the CODESYS master first? That way you can test it without external tools and get a better feeling for it.

Hi, I hope I have read your post good enough for my anwsers to be adequate. A Raspberry Pi 3B should be more then powerful enough for your needs. It can do sub ms cycle times and I doubt your application will need that kind of scan time demands. Also Web visu will not be an issue at all. The built in webserver can easily host large HMI's with many pages. Trends data are logged every minutes during one day, every 10 min for 10000 sample, every hour for 10000 samples. The number of logged signals is...

Hi, A tip: you can also submit your code in the snippets corner as then all submitted code is easy to browse/find/search; https://forge.codesys.com/tol/iec-snippets/snippets/ Plus, offcourse kudoes for the effort, it looks very complete! 😉 PS => Your download button does NOT work at time of my posting

would you be so kind and post a definition or a link to a definition of this RTO timer FB? That would most helpfull, thank you in advance. Maybe OSCAT has this type of timer allready implemented, but without your definition It wll be more difficult to help.

Please integrate this also!👍💪👌

Indeed, VAR_STAT can be seen as if a variable is declared in the body of the parent POU (so an FB or a PROGRAM). In techspeak: the declaration of the VAR_STAT variables are placed on the stack of the parent POU, instead of on the stack of the METHOD itself. To sum it up: 'regular' variables in the METHOD declaration lose their contents after ending the METHOD, while VAR_STAT variables never lose their content after ending the METHOD. I Hope this anwsers your question.

Indeed, VAR_STAT can be seen as if a variable is declared in the body of the main POU (so an FB or a PROGRAM). In techspeak: the declaration of the VAR_STAT is placed on the stack of the parent POU, instead of on the stack of the METHOD itself. To sum it up: 'regular' variables in the METHOD declaration lose their contents after ending the METHOD, while VAR_STAT variables never lose their content after ending the METHOD.

Are you willing to share it on an MIT licensed basis? The projects or libraries corner would be an ideal place for you to showcase and share the code. Looking forward to it!
