Operation

As a microcomputer, the BDA is booted in the same way as a PC. This takes approximately 40 seconds and is started automatically when the power supply is switched on. During this time, the content is loaded from the Flash memory to the main memory, an internal self test is carried out, the operating system (embedded Linux) is booted, and the web server application started.

The RESET button on the underside enables the BDA to be restarted manually at any time.

The LEDs indicate the operating status during the boot-up process. The upper DEVICE LED is first red/green, while the lower CubicleBUS LED is red only. After about 10 seconds, this also changes to red/green. During the load process, the Ethernet connection is checked for a connected network. Only then is the appropriate driver loaded. Since the BDA Plus is to be operated with an Ethernet connection, a physical connection to the Ethernet must already exist during the boot-up process.

Table 4-1The LEDs on the BDA indicate the current operating status.

Figure 4-2For temporary operation, the BDA can be connected to the local interface of the trip unit. In this configuration, only the RS232 connection to the PC is typically used.

Figure 4-3In a permanent installation, the BDA should be connected to the last external CubicleBUS module. It can be secured using a DIN rail, as shown above.
