please delete the contents of the following directory - /var/opt/codesys/.cmact_license/ then start a new SPS and then the activation should work (then you have a new empty UFC SoftContainer)

Thanks for your quick help. It's working until I do a reboot of the raspberry PI. After that it goes back to 2024-04-20. How's that possible?

yes I think you need to build the kernel drivers for the CCAT driver for the backplane ETC networkcard https://github.com/Beckhoff/CCAT/

Do you think there'd be a way to turn this into a library? How would I2C_master be passed down to POU FBs?

Hello, I'm having the same problem. I'm trying to license Codesys running in a Linux container, which I downloaded from the following link (https://hub.docker.com/r/hilschernetiotedge/codesys_control_sl_linux). The same error that you mentioned appears. Is there any solution?

Thank you for your answer. Finally I don't confirm that it used to work before. It seems that the IO-link Package is needed is you want to configure the network, but you don't need it if you use generic IO-link devices.

Seems that the Wago Target does not support the licensing. Either use PFC200 SL from CODESYS Store or ask the Wago support for help.

your device in the device tree is Pi 64 online you have Pi MC (32bit) - update device in the device tree to Pi MC then it will work.

yes sure. Thx for your support! This is the Codesys project stripped down only to my EtherCat and OneWire Configuration. The Project now contains only one OneWire Master on GPIO4.

the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

Could you check the taskcycle time in the taskmonitor (online monitor) - do you really see this 1s on Ethercat Task? Need to check this on my hardware but will take some time...

Is there perhaps a place where I can see examples of programming with different instructions? This would be a great help. Maybe there are some places where ready-made programs are posted that can be downloaded and tested? /Klaus

.. try to use this projectarchive for the Stepper. In case you search for SoftMotion Examples: "c:\Program Files\CODESYS 3.5.21.X\CODESYS\CODESYS SoftMotion\Examples\Tutorial\"

Maybe it is better to use Interfaces to access the objects instead of pointers. But besides that, is "read_obj_ptr" a method? If yes, you need to call it, so add brackets behind the method call: read_obj_ptr();

Hallo zusammen, hi all, ich habe den gleichen Fehler. Auf einem Raspberry Pi geht der Fehler weg, wenn ich alles bereinige und dann vollständig übersetze. Wenn das Projekt im Codesys Development System wieder neu geladen wird ist der Fehler aber wieder da. Mit eine Win V3 x64 PLC kann ich den Fehler nur unterbinden wenn ich auf der HMI das VUM_Login einbinde. Dieses brauche ich aber nicht, da ich die HMI für das User Management selbst gestaltet habe. Das funktioniert auch. I have the same error. On a Raspberry Pi the error goes away if I clean everything and then compile completely. When the project is reloaded in the Codesys Development System, the error returns. With a Win V3 x64 PLC I can only prevent the error if I integrate the VUM_Login on the HMI. But I don't need this because I designed the HMI for user management myself. That works too. Anyone have an idea to fix this problem. Many thanks

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
