Issue Details

What is the purpose of the backup battery in my CompactRIO or sbRIO?

Solution

The backup battery stores the system clock information on RIO targets when the RIO is powered off.

Additional Information

Some RIO models including the sbRIO-9605/9606 and cRIO-9075/9076 do not have backup batteries. Therefore, these models do not keep system clock information when power is not supplied. Please see the following document for more information: System Time On sbRIO-9605/9606 And cRIO-9075/9076.
