Part 3 Controller Data Structure
2.2 Controller with Increased Memory Size (with Gateway Function)
(Other parameter No. 20 = 0 (System-memory backup battery not installed))
The programs, parameters, symbols and positions are read from the flash memory at restart. The data in
the main CPU 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: SEL global data cannot be retained if the backup battery is not installed.
Data edited on the PC
or teaching pendant
Data will be retained while the power
is on and cleared upon reset
Data will be retained even after the
power is turned off
