Breaker Data Adapter (BDA)

WL Circuit Breaker

Brief Description and System Requirements

The Breaker Data Adapter (BDA) is the first circuit breaker parameterization device to feature an integrated webserver for parameterization, monitoring and diagnostics. The BDA Plus also features an Ethernet interface for connection to the Ethernet, Intranet or Internet.

Description

The BDA can be used to read and change the parameters of WL Circuit Breakers, display measured values, as well as visualize, analyze and store diagnostic data.

It is comprised of a microcomputer on which an embedded Linux operating system featuring a web server application runs. The HTML pages and the Java program codes are stored in the internal flash and can be displayed on a browser. The browser itself displays the HTML pages, while the more complex functions are implemented using Java applets. A Java Virtual Machine (VM) is required to run the Java applets. This is available free of charge for a wide range of browsers and operating systems.

All the pages that can be displayed are stored on the BDA in German and English; the language is selected when the data is called up in the browser for the first time. A new language can be selected during operation.

The cable supplied is used to connect the BDA to the WL Circuit Breaker. The BDA can either be connected directly to the trip unit or to the last

CubicleBUS module. The indicator with the browser application (e.g. laptop) is connected to the BDA using a null modem cable.

The Breaker Data Adapter Plus features an additional Ethernet interface, which means that the BDA Plus can also be addressed via the Intranet or Internet. The communication options available via the Intranet or Internet are restricted only by the network administration.

All write actions (changing parameters or switching actions) are password protected.

When connected temporarily, the BDA can be used to read and change parameters, perform diagnoses, or display measured values. For this reason, a magnet is supplied with the BDA so that it can be attached to doors and other elements containing iron. The DIN rail installation kit supplied can be used to connect the BDA permanently. Depending on the application, the BDA Plus is normally used for a permanent connection. In this way, it can be accessed via the Ethernet, Intranet or Internet.

If the WL is to be switched open or closed via the BDA, the MODBUS COM16 module must also be installed. This contains the connections for activating the opening and closing solenoids and the motorized drive.

The MODBUS communication function does not have to be enabled at this point.

Benefits of the BDA:

•No special software has to be installed; the display software is supplied with the circuit breaker data directly from the BDA. The appropriate help pages are also stored directly in the BDA, which means they are always available when they are needed.

•The comprehensive use of Java technology ensures the systems can operate regardless of the operating system. This means that the BDA can be used with all Windows versions, Linux, and all other operating systems provided by the corresponding Java Virtual Machine.

•Smaller hand-held devices with PocketPC as the operating system can also be used, as can PCs or notebooks, provided they fulfill the system requirements.
