Raspberry Pi serves as a CPU of the control unit. Inside there is inserted SD card with a stored control software, RPi itself processes the received signals and sends reactions. All the individual interfaces, inputs and outputs are connected to RPi processor directly over GPIO or non-directly via I2C. Raspberry Pi also provides connection to the network (which allows local or remote system control) and USB (over USB it is possible to connect for example [https://www.unipi.technology/usb-to-serial-rs485-converter-p42 RS485 converter] for Modbus communication).
