RESULT: The controller begins erasing Flash EPROM and displays the
message: Erasing Flash EPROM, please wait. Erasing the Flash-
EPROM can take up to 30 minutes depending on the activity of your
application.
When done, the display window lists options for controlling Flash
EPROM. Continue with Step 3 in the procedure for Saving
Application Data in RAM to Flash EPROM.
Erasing a Specific Application It is not possible to erase one specific application from the EPROM while
maintaining other applications.

Save application to Flash EPROM 3. Press Enter (↵) to select Save Application.
NOTE: The save procedure writes application data to Flash-EPROM. The
save procedure does not affect application data in RAM.
RESULT: If there is sufficient space in the Flash EPROM, the controller begins
saving application data in RAM to Flash EPROM and displays the
message: burning Flash EPROM, please wait.
When done, the display window lists system data.
If the message “Couldn’t burn EPROM” displays, check that the
controller has a Flash EPROM. If it does and there are no hardware
problems, the Flash EPROM is probably out of memory. Erase the
Flash EPROM (previous procedure) and try to save again.
