Part 3 Controller Data Structure
2.2 Controller with Expanded Memory (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
