Post by manuknecht on Detect "Cancel" Press in FileOpenSave Dialog ^{CODESYS Forge talk (Post)}
When using the FileOpenSave dialog and using the Visu_FbFileListProvider FB as an In/Output I could not manage to detect the difference of pressing the "Load" button on the dialog vs. pressing the "Cancel" button. In both cases, the selected file is updated if the dialog is closed when checking using the Visu_FbFileListProvider.GetSelectedFileName() command. How can I prevent reading or writing of a file when the "Cancel" button was pressed?

Post by jkopicz on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
In my project, I have frames that I would like to read the current active index. I change the frame index using the onclick properties of a button, then change frame index. I need to do some logic based on which frame index is selected. Is there a way to read the current active index of a frame?

Post by taqamert on CANopen PDO Issue with Pressure Sensor in Codesys ^{CODESYS Forge talk (Post)}
Hello everyone, I am using an IFM CR0303 model PLC, which has a tilt sensor and a pressure sensor connected via CANopen. Both sensors are from the same brand (ATEK). I can read data from the tilt sensor without any issues, but I am unable to read data from the pressure sensor. I have added the EDS file in the PLC configuration and adjusted the node-ID settings. When I check with the PCAN-View application, I can see that the selected PDOs are coming through, but the data is not reaching the Codesys side. What could be the issue, and what can I try to resolve it? Can anyone help me?

Post by otbeka on CAA File Handling: "Read only" error ^{CODESYS Forge talk (Post)}
Hi, sorry for the late reply. After some investigation, the read-only error was being triggered by a FAT-fs filesystem panic on the kernel end, probably caused by unfinished write/reads causing corruption. I found this thread https://forge.codesys.com/forge/talk/Engineering/thread/e637d252b7/ which seems to give a solution of using SysProcess to send the 'sync' command to the console immediately following a write to prevent issues if power is lost or, in my case, if the unit is harshly power cycled. Indeed this seems to resolve the issue bar the worst possible edge cases.
