System Manual 2CKA000073B9795
The data is stored on an external server.
– In the ABB-Welcome IP system on the server of Busch-Jaeger.
Dynamic Host Configuration Protocol
– In a network, every device requires its own address so as to able to be
recognised in the network. These addresses are allocated automatically via
the DHCP.
Interface between two systems
The transmitter can simultaneously deliver IP data flows to many recipients in
a single step.
Power over Ethernet
– With PoE, network cables supply network-capable devices with current via
an existing data connection. Only one cable is required for the transmission
of the current and data.
Power Sourcing Equipment
– Devices for the infeed of PoE. E.g. PoE switches.
Powered Device
– Device that is supplied via PoE.
Quality of Service
– Optimisation of connection through automatic prioritisation of applications.
A device, a computer for example, can normally communicate only within its
own network. To enter a different network, a device is required that transmits
and distributes the data packages. This process is called routing. The device
that takes over this task is the router.
