The CONTROLLINO MAXI and MEGA have a RS485 interface of the type SN65HVD08. With this interface you are able to communicate with other RS485 interfaces.
RS485 is a serial interface standard capable of data communication with up to 32 receivers at a distance up to 1200m.
The RS485 driver is connected to the UART3 (TxD3 / RxD3) of the ATmega2560.
This is an example guide to setting up Modbus TCP communication between a client and server using CONTROLLINO and an Ethernet shield. This tutorial will
