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

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.
