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
