Ok it's working with Codesys now using Syscom library.
We had to add the following in /etc/codesyscontrol/CODESYSControl_User.cfg and not in the CODESYSControl.cfg

[SysCom]
Linux.Devicefile.1=/dev/ttyACM0
portnum:=COM.SysCom.SYS_COMPORT1

thank you for that Dirk.

Any suggestion for making serial ( ttyACM0 on linux in ascii mode) with Codesys ?
Because if not we will jump into Python which is working and free




pi@RevPi110436:~$ udevadm info -q property -n /dev/ ttyACM0
DEVPATH=/devices/platform/soc/fe980000.usb/usb1/1-1/1-1.3/1 ...

Ok :
- I reinstall CODESYS V3.5 SP 20 Patch 5
- I re install RevPi linux Os from Bullseye to bookworm

Now I can connect and begin to work on the project itself

Hi all,
We recently bought a RevPi Core S with profinet or profibus gateway.

So we we want to control an High frequency generator with a PLC by Profinet Or Profibus. Our issue is that this generator can only be driven through serial UART.

Were I'm :
- bullseye installed and up ...
