Post by valenting on License problem with Raspberry Pi ^{CODESYS Forge talk (Post)}
Hello, I have a raspberry pi with a license installed, but Codesys stops after 2 hours, and when I start it manually I have the following message: pszInfo=!!!! no runtime license - running in demo mode(~2 hours) I tried using License Manager, and got the following message: Licensing info not available. There is no dongle attached to the device. I have this message frequently, and usually removing the content of /var/opt/codesys/.cmact_license makes it work. After doing it and restarting Codesys, I have an empty Softcontainer without my License. I tried using "Install license" using the .WibuCmRau file for the corresponding license and got the following message: Licensing info not available. The device does not support this service. I also tried using Additional Functions > Restore Licenses with the Ticket ID and got the following message: This device does not support automatic license backup. How can I reinstall the license to this Raspberry Pi?

What do the details show? Is it requesting an online change or download? If the compile file is missing, it will request a download. Several things can trigger an online change, if you haven't changed the code, likely libraries. The details should provide some guidance.

To simplify your problem you shall not select dongle and get dongle errors. Do as shown In some cases you need 2 different licenses depending on the metrics. And yes the system gives not always give proper error messages when you try to reinstall a license

yes, but you could use a demo project in the analyzer to check other types: https://analyzer-eu.automation-server.com/help/en/tags this should work.

I have a question for the Visu File Transfer Example. Is it possible to transfer more than one file from the plc to the webvisu with only one button click? How can i realize it?

I experienced the same problem: using __VARINFO is working only in PRG context, while it crashes if used inside Function Blocks. I would really appreciate if they would fix this issue

Hi kenth1973, no, we do not have this kind of information on internal variables. iPhasingState has been removed and is no longer present in current versions of SoftMotion. Best regards, Georg

Hi kenth1973, it is not a matter of who created the function block. It is just that we don't have, and don't provide, documentation about internal implementation details... Hope you can understand that, Georg

Are you sure you need to read holding registers? Have you tried reading input registers?

Post by blitz on Can't get SMC_SmoothPath to work ^{CODESYS Forge talk (Post)}
So in my case the solution was that I had both smooth path and round path in the code. Both blocks had their own buffer and seemed completely separate but still triggering Execute on both caused the mentioned problems. When I blocked Execute the problems disappeared.
