BDA/BDA Plus Description WL Circuit Breaker BDA Plus as an Ethernet Interface In addition to the previously mentioned functions, the BDA Plus enables data to be accessed via 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 communication without the PROFIBUS/MODBUS 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 via the BDA Plus.

System Requirements WL Circuit Breaker System Requirements Certain prerequisites have to be fulfilled before the BDA or BDA Plus can be operated. One of the two standard browsers (Internet Explorer V5.5 or higher or Netscape Navigator V6.2 or higher) must be installed on the output device (e.g. laptop). Compatibility with other browsers cannot be guaranteed. To ensure independence between the operating systems and browsers, all the pages have been written in HTML code and Java applets. A Java Virtual Machine is required to display the pages. What is Java? Java is a platform-neutral object-oriented programming language originally developed by Sun Microsystems. Java is implemented in all IT areas of the commercial, industrial and administrative sectors, and is available on the internet for many operating systems and platforms – including cell phones and real-time mainframe systems. Unlike most compiler languages, Java applets are not directly translated into a set of commands that can be understood by a “Real Processor.” Instead, they are first converted to the “Java Byte Code.” Although this byte code is highly machineoriented, a “Java Virtual Machine” (VM), which emulates a standardized processor for all Java applets, is required on the target computer. Since Java normally compiles data twice (once with the developer and once with the user), this principle is known as the “Just-In-Time“ (JIT) Compiler. Java applets take longer to start since the machine code is generated during initialization. WL PROFIBUS/MODBUS Communication and Electronic Accessories However, the same Java applet can run on all supported systems without modifications. The Java Virtual Machine V2 V1.4.0_01 may be required to display the BDA pages. When these pages are called up for the first time, the BDA checks whether Java VM2 is available on the browser. If not, the system automatically displays a window informing the user of this and automatically links the user to the appropriate Sun Microsystems page. An Internet connection must be established to ensure the automatic installation procedure functions properly. If this is not the case, the Virtual Machine required for the Microsoft Windows operating systems can be downloaded from the following address: http://java.sun.com Once installed, the option Java 2VM must be activated in the browser (if it is not already). To avoid conflicts with other Java versions, it is recommended that you uninstall older versions of Java and delete the cache in the browser. The target system with the browser also requires one or both of the following communication interfaces: • A serial interface with RS232 design, usually integrated on standard PCs (e.g. COM1) for point-to-point (PPP) communication with the BDA. • A LAN interface for communicating with the BDA Plus via Ethernet. SECTION 5 Circuit Breaker Requirements The BDA can be connected to WL Circuit Breakers with the following trip units: ETU745, ETU748, ETU755 and ETU776. It can be connected either directly to the trip unit test socket or to the last external CubicleBUS module. Getting started with the BDA Plus If the BDA Plus is being installed for the first time, the settings for the IP address and the standard gateway as well as the subnet mask must be set using the serial communication via RS232. After this the BDA Plus must be rebooted to load the Ethernet driver with the specified parameters. 5/4
