4 Connections and interfaces
The following figure shows DANEO 400 with the interfaces located on the front panel.
There is only one interface on the rear panel: the socket for the power supply.
4.1
Ethernet ports
DANEO 400 has three Ethernet ports. Two of them are in the group NETWORK and are labelled A
and B. These ports will be referred as the "process ports" in the following.
A third Ethernet port is in the group CONTROL and is labelled ETH. This port will be referred as the
"control port" in the following.
Network interfaces (A, B) – Process ports
4.1.1
The process ports are primarily intended for capturing traffic from the "process", in our case the
communication network of the power utility automation system. The two ports can be either individually
used or they can be combined to form a tap (see below 4.3.1).
When the process ports are used individually, the captured traffic flows "one-way" into the port. If
required, DANEO 400 can be also controlled through one of the ports A or B.
When the process ports are combined to form a tap, the traffic received on port A is transmitted from
port B and vice-versa. For capturing, it can still be selected from which of the two ports the incoming
traffic is to be captured. In tap mode is not possible to control DANEO 400 through one of the process
ports.
4.1.2
Control port (ETH)
The control port is primarily intended to control DANEO 400 via a network connection. In addition, you
can also use the ETH port for capturing traffic, even when the port is actually used for controlling
DANEO 400.
