The Save to Flash exclamation point (!) (bang) shows on a Continuum BACnet controller object and indicates that the controller 'requires flash backup' but won't save to flash.


The Save to Flash exclamation point (bang) shows on a Continuum BACnet controller object. Hovering over the icon, a tooltip comes up indicating that the controller 'requires flash backup'. However when performing a backup to flash, a result comes back that the 'controller doesn't need flash backup' and the exclamation icon remains. Re-loading the controller and performing a send to database have no effect.
