| If you set any other IP address or enable [[wp>DHCP]] support, the Ethernet component will be started before any VI is executed. This leads to longer boot time and can block the program (when no network is connected) before a watchdog can be set up or a life sign can be given out. The settings (IP adress, gateway, MAC address...) cannot be chaneg at runtime. | If you set any other IP address or enable [[wp>DHCP]] support, the Ethernet component will be started before any VI is executed.
