more detailed:
there are several Options:
for a wetterstationconnection l viewtopic.php?f=23&t=6247&p=13503#p14144 l we use this RS485 modul on the PI http://www.amescon.com/de/produkte/raspicomm.aspx
for this you need to install it and add to /etc/CODESYSControl.cfg [SysCom]
Linux.Devicefile=/dev/ttyRPC
portnum := COM.SysCom.SYS_COMPORT1;
use any USB to Serial converter and add to /etc/CODESYSControl.cfg [SysCom]
Linux.Devicefile=/dev/ttyUSB
portnum := COM.SysCom.SYS_COMPORT1;
In CODESYS you could use SysCom or CAASerial Com, think you will find here some application examples.

Hi,
could you attach the project and give more details what you have already done?
Does the serial com work under Linux?
