1.3.2 Registers Screen

The Registers section contains parameters used to monitor gauging. The Bit Registers section provides bit level picture of status and fault registers. A green flag indicates that the bit is 0 (low state) and a red flag indicates that the bit is 1 (high state). A greyed out bit indicated that bit is reserved. Data begins to appear once the Refresh (single-time scan) button is selected, or it scans continuously if the Scan button is selected. The continuous scanning period can be set via the | Windows |preferences| register selections. Please see Register Screen for green and red flags reference.

The Battery Management Studio program provides a logging function which logs all the values of the parameters in the Register section if running the program in “Show basic view mode”. In order to selectively choose the parameters of Register section that are scanned and logged, the user needs to set Battery Management Studio to “Show Advanced view mode”. This mode can be set via | Windows |preferences| All Global Settings| Show Advanced Views. Uncheck the fields that are not needed to be scanned or logged. To enable logging, select the Log button; this causes the Scan button to be selected. When logging is stopped, the Scan button is still selected and has to be manually deselected.
