Beside CAASerialCom using Syscom.library is possible too.
Here is the example for it.
(See l viewtopic.php?f=21&t=5699 l for CAASerialCom example)

on Linux side you need to indentify your serial port and activate it in /etc/CODESYSControl.cfg

How to do this:
1. you need to check on linux side which tty port is available.

Example a USB to serial converter:
Check under Linux with 'dmesg' which device is used for it:

in my case it reports: ttyUSB0

so you need to add in /etc/CODESYSControl.cfg
(Attention you need to remove the 0 from USB0)

[SysCom]
Linux.Devicefile=/dev/ttyUSB
portnum := COM.SysCom.SYS_COMPORT1;

this was the pi side under Linux

1. then after reboot or restart plc, you could communicate via serial com

here I can show example of saving INT values int txt file on Raspberry Pi SD

I have used pymodbus TCP to create modbusMaster(client) on port 503, with 10 holdt_register and 10 input_registers
in Cosesys v3 create ModBusSlave TCP also with 10 holdt_register and 10 input_registers,

if raspberry pi shut down , at start you can get 10 int values from file vars.txt on SD

How to make start at boot pymodbus master(client)

using PuTTY:
#sudo nano /etc/init.d/autorun

and paste text from autorun.txt
Ctrl + x
y
Enter

#sudo chmod 777 /etc/init.d/autorun
#sudo update-rc.d /etc/init.d/autorun defaults

#cd /home/pi/Documents/pymodbus/examples/common

root@raspberrypi:/home/pi/Documents/pymodbus/examples/common# sudo nano test.py

and paste text from test.py.txt
Ctrl + x
y
Enter

before ShutDown RaspberryPi Download CodesysProject and try:

#sudo /etc/init.d/autorun start

output:

Starting autorun
done
wait to start ethernet , wait for Codesys Slave to start 20sec

Prefered Interface (USB to RS482 Serial adapter)
https://www.amazon.de/gp/product/B00GWE ... UTF8&psc=1
(Advantage does not use any specific kernel module - you could use latest Debian)

For Raspi Comm the following is needed:
/etc/CODESYSControl.cfg

[SysCom]
Linux.Devicefile=/dev/ttyUSB

maybe another options is:
Link: http://www.elsner-elektronik.de/shop/de ... rs485.html
RS485 Extension: RasPi Comm

For Raspi Comm the following is needed:
/etc/CODESYSControl.cfg

[SysCom]
Linux.Devicefile=/dev/ttyRPC

wget http://downloads.amescon.com/rpc_setup.sh && chmod +x ./rpc_setup.sh && sudo ./rpc_setup.sh

sudo raspi-config
enable:
1. Devicetree
2. I2C
3. SPI

RS485 Port is
