Hi,

I'm trying to read analog inputs on a Modbus RTU device.

The COM Port doesn't work.

I added the SysCom in CODESYSControl_User.cfg.

Any suggestion?

Best Regards
Thanks

Hi Straccio80,

did you try Com Port number 2 in codesys. Because Com port 1 is used for the rs232 console port.

Hi,

i fixed the problem.

In CODESYSControl_User.cfg i setted

[SysCom]
Linux.Devicefile=/dev/ttyUSB

instead of

[SysCom]
Linux.Devicefile=/dev/ttyRS485

and it's working fine.

Best regards
