our Modbus example is only for Modbus RTU – which means Modbus over RS485 serial line.
But the ArduinoModbus library should work also over Ethernet. CONTROLLINO MEGA should be compatible to Arduino Mega + Ethernet Shield.
Do you have any progress so far?
Have you tried to connect to you robot from some Modbus client app running on a PC?
