2.2 Saving Data
When data is created/edited using the PC software or teaching pendant is sent to the controller (or when the
[WRT] key is pressed on the teaching pendant), the data is stored in the controller’s temporary memory. The
data stored in the controller’s temporary memory will be erased once the controller is powered off or restarted
(via software reset). For important data, always write to the flash memory so that they will not be lost.
Note: Global data (variables, flags and strings) and error lists will be erased once the controller is powered off
or restarted (via software reset). (These data cannot be retained after the power is turned off.)
The error list is retained after a software reset, but will be cleared once the power is turned off.
Content 1: Parameters other than content 2 and encoder parameters
Content 2: Parameters of driver card, I/O slot card (power system card)
Content 3: Flags, variables, strings
Since the programs, parameters, symbols and positions are read from the flash memory at restart, the
data in the temporary memory will return to the original data before editing unless the edited data are
written to the flash memory. The controller always operates in accordance with the data in the temporary
memory (inside the dotted line) (excluding the parameters).
