5.7.6 Memory map
The RSEL has a storage area by holding memory and a storage area by flash memory.
When data is transferred from the PC software or teaching pendant to the controller, the data is
only written to the main CPU memory as shown in the diagram below and will be erased once
the controller is powered down or reset.
For important data, always write to the flash memory so that they will not be lost.
Since the programs, parameters and symbols are read from the flash memory at restart, the data
in the temporary memory will remain the same as the original data before edit unless the edited
data are written to the flash memory.
The controller always operates in accordance with the data in the main CPU memory (excluding
the parameters).
Note: The first 10% of the position data is stored in non-volatile RAM and the rest in flash memory.
Comments for each position data can be used for up to 10,000 positions regardless of the
position number, and are saved in flash memory.
Data edited on the PC
or teaching pendant
Data will be retained even after
the power is turned off
