Post by lisawilliam on Top Modafinil Tablets for Productivity and Wakefulness ^{CODESYS Forge talk (Post)}
Modafinil tablets are often discussed for their role in supporting productivity and maintaining wakefulness during long or demanding days. Many users look for options that help them stay alert, focused, and mentally consistent without frequent drops in energy. Because of its wakefulness-promoting effects, Modafinil has become a common topic among those aiming to improve concentration and handle extended work or study sessions more efficiently. In discussions around Modafinil Australia, users share their experiences with different tablet options and how they fit into daily routines. Preferences can vary based on factors like timing, dosage, and individual response, but the goal remains the same—achieving steady focus and sustained energy. It is generally seen as a supportive option for productivity when combined with a balanced lifestyle and good sleep habits.

Hi to all, I receive an error when I try to compile a project that in v.3.5.21.50 have no problem. The error seems to comes out when I add the Visualization part into the project. The complete error is: [ERROR] Internal error:System.AggregateException: One or more errors occurred. ---> System.Exception: Internal error in Code ---> System.ArgumentNullException: Value cannot be null.

Post by away on Visualization stops responding ^{CODESYS Forge talk (Post)}
Hi @spiritcore, Did you find a resolution to this? I'm running into a similar issue using TargetVisu when a user uses the login. It only happens sometimes, and when it does the login/logout buttons still work but the other buttons on the screen don't work.

Post by mohi on Connect to Azure IoT Hub ^{CODESYS Forge talk (Post)}
Hello, I try to connect a Controller to Azure IoT Hub using a Root Certificate put on the controller in /etc/ssl/certs und SAS Token for IoT Hub instead of X.509 certificates. The TLS Handshake is successful when I test in terminal using openssl. It seems that the Controller doesn't start this process. I use the Azure IoT Hub library and the Net Base Services. Is there something left or something you can recommend? Best regards Mo
