Hello, I have been reading some old post but IΒ΄m not enable to connect my Raspberry Pi to a modbus USB - RS485 adapter. I haver a Raspberry 4 with the last version of the CODESYS Control runtime on it. I have configured the .cfg file as you said in other posts:
portnum := COM.SysCom.SYS_COMPORT1;

And apparently in CODESYS the port is working but the slave is giving me a a Timeout error IΒ΄m unable to resolve in spite of have modified it.
I attach some images.
