Operating the device in the local network (LAN)
NOTICE
Do not connect the device to a public network (e.g. the internet).
An Ethernet/IP-based network connection (LAN) is required to operate the device in a local network. In its delivery state,
the device is configured to obtain the IP address automatically from a DHCP server operated in a LAN.
NOTICE
Check the IP address carefully during the conversion for a manual configuration before connecting
the device to the LAN.
An incorrectly-entered IP address can cause IP conflicts in the network and thus disturb another device in your
network.
In the LAN with a firewall, only permit connections to and from the device which correspond to the intended use of the
device. All ports not used are blocked on the device side.
