Thank you wollview, it is clear now, it is due to security reasons that access to the file system is restricted.

I have code written since version 3.5.16 to access the USB drive, how can I do that now the file access has been taken away? I have tried adding a sybolic link to the usb drive in the following directories: /var/opt/codesys/PlcLogic/ /var/opt/CODESYS/PlcLogic/ /opt/CODESYS/PlcLogic/ I still recieve a "FILE_OPERATION_DENIED" response when accessing the USB drive.

Post by docker on Webvisu client connection monitoring ^{CODESYS Forge talk (Post)}
Hi, i am interested in this thread and have tried a couple of the above examples in to determine remote webvisu access. I am having trouble getting the lastusage variable to refresh during runtime? It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Hello. I am using TI AM64x evaluation board TMDS64EVM. It has 8 leds connected via I2C to SoC.I wanna control them via codesys GPIO device. Is that possible? If so how I can do it. I had no problem installing codesys runtime, and running program on device. But when it comes to GPIO access, It couldn’t make it.
