Hello Tim, I am using CODESYS Visu V4.8.1.0. It works when I turn off the "Support client animation and overlay of native elements". But if I do that, dialog box moving and other options are also disabled so it is a bit problematic. Thank you for helping.

No that is not possible for function blocks, although it is possible to that with methods and functions as you see in your second pic.

Hi, how do you change the Git local repository folder name? It is called "project" by default, so we would like to rename it to something more descriptive especially for the remote repo's sake. Thanks!

I'm having right now trouble if the NVL is 'big' and I've needed to reduce the size. It sends for (about) 1 hour then stops.

... and SP21 P6 also. Kind of bummer, migrating from TIA Portal to Codesys for PLC educational courses. These kind of bugs, and other deficiencies, really makes me regret my choice.

Post by charly29160 on CmpCharDevice blocks gpiochip access on Raspberry Pi 5 since update from SP18 to SP21 ^{CODESYS Forge talk (Post)}
Hi, after updating CODESYS Control for Raspberry Pi SL from patch level 18 to 21 (currently 4.21.0.0), the IoDrvGPIO driver ("GPIOs B+/Pi2") can no longer open any GPIO chip on a Raspberry Pi 5. Log output on login: Could not open GPIOChip0. Access to path /dev/gpiochip0 not allowed. Add /dev/gpiochip0 to permitted paths in configuration file if required Could not open GPIOChip4. Trying to open GPIOChip0 Access to path /dev/gpiochip4 not allowed. Add /dev/gpiochip4 to permitted paths in configuration file if required Could not open any GPIOChip. System details: Raspberry Pi 5, 32-bit Raspberry Pi OS (armv7l), kernel 6.12.47+rpt-rpi gpiodetect correctly shows gpiochip0 [pinctrl-rp1] (54 lines) as the RP1 GPIO controller Runtime: CODESYS Control for Raspberry Pi SL 4.21.0.0, Runtime Toolkit SP21+ This worked without issues before the update to SP21. I've tried adding the following to CODESYSControl_User.cfg without success: ini[CmpCharDevice] Linux.DevicePath.1=/dev/gpiochip0 Linux.DevicePath.2=/dev/gpiochip4 Could you tell me the correct section/key to whitelist /dev/gpiochip0 (and /dev/gpiochip4) for CmpCharDevice? I suspect this is part of the general security hardening introduced around SP21 (similar to ForceIecFilePath for SysFile, or the new Gateway "accept local clients only" default), but I couldn't find it documented anywhere. Thanks in advance!

What do you think about having an AI Agent specialized in ST programming in Codesys? I see this saving hours and hours of work for those who program on a daily basis.

For me going to Project -> Project Settings -> Visualisation -> check "Visible" and then check both "Activate property handling ..." and "Activate implicit checks ..." solved the problem.
