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...

Subject: Curtis 1229-4105 CANopen (CiA 301 / CiA 402) Hello everyone, I am developing a battery-powered industry vehicle using a Curtis 1229-4105 motor controller together with a Siemens S7-1200 PLC and an HMS (Ixxat) CANopen Master. I am looking for someone who has practical experience with the Curtis 1229-4105 CANopen implementation. I would appreciate your help with the following questions: Does the Curtis 1229-4105 support only CANopen CiA 301, or does it also support CiA 402? Is an EDS file...

I've been moving in the same direction. For new libraries, I'm trying to minimize dependencies on APIs that look like they're being phased out unless the documentation explicitly recommends them. For synchronization primitives like CAA.BOLT and CAA.SEMA, I'd love to see an official replacement or abstraction layer that's guaranteed to remain stable across runtimes. That would make library development much cleaner than relying on platform-specific SysLib* implementations or conditional compilation...

I am trying to use Codesys to connect by Modbus RTU to an Arduino UNO, I add the Modbus COM Port but when I try to add the master and the slave I don't have these options, I attach an image of the device manager. I am using Codesys 3.5 SP21.
