Currently the CODESYS Control Basic S license is not a network license but it should be, so I guess it doesn't work yet

Post by yoeri on Refresh visulization realtime ^{CODESYS Forge talk (Post)}
Hi everyone, I need some help with displaying an image (test.png) on my device. Initially, showing the image is straightforward. However, I want to be able to update the image dynamically. My goal is to send updated files via FTP to the device, and have the display automatically show the latest version of the image. All images will be sent with the same name (e.g., test.png). Currently, I can see the updated image after sending it via FTP and performing a warm restart, but I'd like to achieve this in runtime, without having to restart the display or application. Does anyone have suggestions on how to implement this? Thanks in advance!

Post by imuser on Is it possible to use debug functions such as Step Execution while the PLC ladder is in Running? ^{CODESYS Forge talk (Post)}
Hello, I am a student learning CODSIS. Lately, I've been curious about something. During the actual PLC run, that is, Assume that the I/O is connected to a physical device and the analog value is updated in real time. Is it possible to use a feature like Codesys’ Debug-Step Over-Step IN? If possible..... How do I process the values of analog values (pressure sensor, temperature, current, etc.) that are being updated in real time? To step over, the ladder must stop at the breakpoint. If that happens, the PLC will actually stop, right??
