I am attaching the project done with M-DUINO and Raspberry Pi 3.
In this project Raspberry with Touch Screen 7 ", is ModBus TCP master function,
and M-Duino (Arduino Mega) has ModBus TCP Slave function.

The CodeSys project are including :
1. Alarm Manger
2. Language manager
3. Data Base (like retain variable) is a file on Raspberry SD card
{if Raspberry suddenly turns off, the configuration data is retrieved from SD.}
4. Visualization
5. Ladder function example
6. ModBus TCP Master
Great work. Ineterresting example
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hello,
I want to do similar thing as you, to make the Arduino Mega to become I/O for Raspberry Pi. But I have a problem with connecting Arduino to Raspberry (i can ping arduino from Raspberry). Should i configure something from RPi side yet? For Arduino I have based on your program (but i had to use Ethernet2 library) and configuration for Codesys seems the same as yours (except chanels for modbus slave). In online i can see this:
