Part 3 Controller Data Structure
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 temporary memory (inside the dotted
line) (excluding the parameters).
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
2. When the System-Memory Backup Battery is Not Used
Other parameter No. 20 = 0 (System-memory backup battery not installed)
Since the programs, parameters, symbols and positions 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 temporary memory (inside the dotted
line) (excluding the parameters).
Note: SEL global data cannot be retained if the backup battery is not installed.
