Post by valenting on License problem with Raspberry Pi
CODESYS Forge

(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?

Hi kenth1973, MC_Phasing has been improved in recent versions. I would recommend to install the latest version of SoftMotion (4.20.1.0) and test whether the problem still exists, and if so, what the error identifier is. (Also check the PLC log in this case, it might contain additional information.) Setting the internal state of the FB is not recommended, it could lead to malfunction of the FB and unintended movements of the drive. Best regards, Georg

Hi kalmeyer, I would recommend to have a look at these examples. They come with a project and a description: https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_examples_single_axis.html. Best regards, Georg

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

Post by jbcregen on Accessing parameters from a structure or function block with the web interface
CODESYS Forge

(Post)
I have a project with hundreds of OPC-UA variables available on the network. A lot of these variables are used actively in various scripts that run in background in the OS (Linux). I'm experimenting with Automation Server and I have a hard time understanding how the web interface populates its parameters list for a given PLC (<plc details="" parameters="" for="" plc="" 'xyz'="">).</plc> In this page, it looks like the only variables available are the ones that are of a "base" type : bool, TIME, String, INT, etc. All the variables that are nested into function blocks or structures are not available in the web interface, even if they are available to any OPC-UA client. Is this a limitation of the Automation Server or is there something that can be done in Codesys?
