CiDRA Use of Foundation Fieldbus Protocol with SONARtrac Transmitters - Manual (Page 41)

It is important to note that ‘written’ simply indicates that changes have
been sent and acknowledged by the transmitter, but NOT written to
FLASH yet.
A3.1 Changes to FLASH
To write the changes to FLASH, click the ‘Auto’ button. All changes
must be accepted before hitting the ‘Auto’ button, or changes will not
be written, and Configurator will indicate an error has occurred.
When the ‘Auto’ button is clicked, the transmitter validates all changes
made and will modify anything that is invalid back to its previous
value. The only way this is indicated is that Configurator will show the
previous value.
No error messages are displayed. The user must confirm that
changes were accepted by inspecting what Configurator shows after
returning to ‘Auto’ state and the device is given time to update the
Configurator display.
A3.2 Undoing Changes
To undo changes without saving them, click the ‘Auto’ button, then the
‘Read All’ button. Configurator will remove the asterisk and refresh
the value that was changed.
