The above picture shows four different screen shots from simple to more detailed.  Note that there where no slaves plugged in with the upper left screen shot that shows zero voltage for the pack (oops).  
The upper right screen shows low, high and average cell voltages for entire pack and low, high and average temperatures for pack, that there are 3 out of 3 slaves and 28 out of 28 cells communicating and that the state of
charge is 98%, the pack voltage is 107 and no current is flowing.
The lower screens show the detailed cell voltages and temperatures for slave #01

This is the main screen showing that one master controller exists on the CAN network and that there are 18 devices within that controller that can be configured (16 slaves, the pack itself and the LCD screen)

This shows the main configuration screen for the pack itself with this tab giving a look at
all the individual cell voltages and temperatures.  At the top is all the pertinent pack information

This tab contains the configuration for the pack capacity which in turn is used to determine the SOC and watt hours remaining.  The current sensor can be any sensor that is 5v based with a zero current reading around 2.5v  To allow for an offset from 2.5 volts, the zero current set point can be adjusted from 1.9 to 3.1v  By simply plugging in the mV setting for a current sensor you can use any range of sensor, from a few amps to thousands of amps.

This tab allows you to set the individual warning and error thresholds for the individual cells.  Note that there is a warning and error threshold which is really meant as giving you two individual set points for each.  For example, this allows you to trigger a buzzer if any cell voltage drops below a certain point and turn off the pack if a lower threshold is reached.  Or, conversely, you could have your charger respond to one upper voltage to go from a constant current mode to a constant voltage mode and then have a higher threshold to end the overall charge.  
Note that for each warning or error, you can choose whether it activates any of the outputs.  Also note that the relay is special in that it releases if any of the warnings or errors occur (that have the R1 checked)  This ensures that if the relay is used to enable charging (for example) that a power off condition, a micro reset or any of the warnings or errors will release the relay and stop the charging.
In the above example, the relay will release if any cell goes to 4.2volts and the Out1 is connected to a buzzer and will activate if any of the 4 conditions apply.  The Out3 output will activate if any cell voltage hits 4.1v



 

This screen shows the similar warnings and error thresholds for the pack itself.  In this case, the Out1 output will trigger on any of these conditions and the Out2 will trigger on an over current situations.

When you choose to configure an individual slave board, you are presented with this screen.  From here you can see all of the cell voltages with the low, high and average voltages as well as temperatures.  I think the rest of the configuration is self explanatory.  Communication errors are monitoring and displayed on this screen to give advanced warning of potential wiring issues.




This tab allows you to configure the cell balancing method should you choose to enable it.  You can set the balancing to either turn on at a certain threshold (4.15v in the above example) or if the individual cell exceeds the pack average by a set amount (in 50mV increments)  You can also set the maximum number of cells to balance at any given time.  This can serve a couple of purposes,
1) if you are using the internal 6802 balancing mosfets and you don't want to heat the device excessively or
2) you are using larger external balancing mosfets and resistors and you don't want to heat your pack excessively.  

The lower portion of the screen allows you to manually lower any cells voltages and have them turn off at a certain threshold, in this case 3.75v




This screen shot shows the balancing set to 3.7 volts and shows that all 12 cells are (A)utomatically in balance mode but only 5 are actually on because we have set the max # of cells to balance at 5.  In this case, because the cells are so close in voltage, the balancing will jump around from cell to cell because as the balancing turns on, it will lower the cell voltage slightly which in turn will cause another higher cell to be switched on at the next check.





This screen shows the manual (O)verride feature turned on with the same 5 cell limit being enforced.

This screen shows the final tab that has a graphing function to look at the individual cell voltages.  In this case, I have a 4 cell E-Moli pack and was discharging it at close to 10 amps (these are 2.9Ahr cells) and you can see how quickly the cells go from a safe 3 volts down past their lower 2.5 volt limit (less than 10 seconds)  You will also note the number of alarms that are going off, highlighted by yellow and red conditions (no cells were hurt during this test!)
