OK, can be, that You have another Problem.. but this need more description of Your issue.. In Raspbian is neccessary to allow control of GPIO in "Interfaces - Raspberry Pi Configuration". I hope, this You have set if You uses Python. Which CODESYS and runtime version do You use? Do You set outputs or read inputs? Can You send some printscreens or whole project is best...

Here is detailed picture how to change GPIO control... Update Device for GPIO:

Hello, I solved this issue with use of new CODESYS runtime V3.5.16.20. There I used new GPIO driver: "GPIOs B+/Pi2". (The older was named "GPIOs A/B" and worked me only on RPi3B+). Lubos

Hello, I have problem to control GPIO pins on Raspberry Pi 4. I use latest CODESYS runtime Version 3.5.16.10. I can control GPIO from RPi 4 system (e.g. Python code), but not from CODESYS. I tried older runtime Versions too, another RPi 4 device, but nothing helps. On Raspberry 3B+ function everething without problem. Did You tried this or do You how to solve this issue? Thanks.
