BDA Plus as an Ethernet Interface
In addition to the above-mentioned
functions, the BDA Plus enables data to
be accessed via the Ethernet. In this
case, the circuit-breaker data is not
transmitted as net data, but displayed
on HTML pages in an
application-specific format. The
BDA/BDA Plus cannot be used to
integrate the circuit-breakers in higher
level visualisation systems, such as
WinCC. If it is to be possible to display
several SENTRON VL/WL circuit-breakers
round-the-clock online using the
communication system in a switchgear
unit without the PROFIBUS-DP, one BDA
Plus is required for each circuit-breaker.
In this case, the circuit-breaker is
selected by entering the BDA-specific IP
address in the browser. Password
protection in the BDA and BDA Plus
prevents unauthorised access.
By making the appropriate settings on
the firewall, the SENTRON VL/WL
circuit-breakers can also be accessed via
the intranet and Internet.

Depending on the network settings (routing tables and firewall entries), the
circuit-breaker can be diagnosed by all PCs with an Internet connection.
