Controller always indicates that a backup to flash is needed.

Issue

Shortly after a successful backup to flash the exclamation point appears again on the controller's icon in the Continuum explorer indicating that a backup to flash is needed.

Product Line

Andover Continuum

Environment

  • CyberStation
  • bCX9640
  • bCX4040
  • CX9680
  • ACX5740
  • ACX5720

Cause

  1. PE program changing configuration attributes.
  2. A setpoint changes value.

Resolution

Any changes to a configuration attribute will cause the database in the controller to be marked as needing backup up to flash.

Also, if an object is configured as a setpoint, changing its value causes the database to be marked as needing backup to flash.

Find and modify any PE programs that change configuration attributes (i.e. description, format)  and/or setpoint values.
