BDA
Plus
as an Ethernet Interface
In addition to the previously
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 visualization systems.
To display several WL Circuit Breakers
around the clock online using the
communication system in a switchgear
unit without the PROFIBUS module,
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
unauthorized access.
By making the appropriate settings
on any firewall, 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.
