Reading data stored on the module can be done via polling, which is more suitable for simple programs, or via interrupt, which is used in more advanced programming. The identification of the IP address of the modules assigned by the DHCP server, the configuration of the ports and signal lines (input: TTL, CMOS, Schmitt Trigger or output), the reading/writing of the ports and the use of the EEPROM memory are additional programming options for the module. Some advanced programming for the module includes setting a fixed IP address, default power-on state, auto scan mode, and resetting the
