Communication & interaction
DNS: Domain Name System
Access to the controllers via fixed naming conventions. When establishing communication between two controllers, it is not necessary
to know the IP address of the target controller, only its name. The IP address can be requested from a DNS server using this name.
Devices are no longer controlled via meaningless IP addresses. The structure and availability of individual networks is specified once
and does not have to be constantly adjusted according to the available IP addresses. This make systems easier and more intuitive to use.
Networks involving several participants can be documented more clearly.
Examples using DHCP and DNS
Integrating devices in networks is easy. A DHCP client automatically receives the network parameters from a DHCP server. This means
that controllers can be integrated in existing networks without knowing the network parameters. The controller is simply accessed
using the name.

PG5 device configurator.
FBoxes
Specific network administration FBoxes can be used to distribute the DNS names
of other stations via the application program and verify communication with
the PING FBox.
