Post by durallymax on Source code changes since last download CODESYS Forge talk (Post)
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.

Post by pernockham on Persistence Manager: Config File not found? CODESYS Forge talk (Post)
Trying to utilize the persistence manager, but system do not write to file and do not create the config file. System is a Linux SL, version 4.13.0.0 Problems with persistence/config started when I had other problems to go online, I deleted the config file and the persistent files, but the system will not re-create them. I have tried to remove/re-install the "PersistenceManager"-module, create the folder-structure myself. And also reinstall the linux-runtime but its clearly not working. Any help appreciated.

I ran into a problem. Uploaded an example (https://content.helpme-codesys.com/en/CODESYS%20Examples/_ex_uacapi_example.html) After launch. on the emulator. I see that I am having problems: - UaExpert does not connect. There are many servers but no connection. - I can’t transfer the certificate from quarantine to trusted ones. There is some problem with creating the certificate. CS 19.2. If anyone has had similar problems, please give me advice. Thank you.

Post by timothyzalusky on Missing Device Descriptions in Repository CODESYS Forge talk (Post)
After updating my Codesys to later versions, it seems my device repository no longer lists the proper runtime devices, nor ethernet adapters, or other previously installed device descriptions. What needs to be done here? Do I need to uninstall and do a clean install? I am now updating to SP21.1 to see if that fixes it. Any tips what I am doing wrong here are much appreciated. I don't see codesys control win, or have the ability to add an ethernet adapter in my project.
