MEMORIES AND FILES USED IN CPU MODULE
3) Set to the DIP switches of the High Performance model QCPU, Process CPU
or Redundant CPU to positions indicating a parameter for valid drive.
• When SRAM card is installed••••••• SW2 : ON,SW3 : OFF
• When Flash/ATA card is installed ••SW2 : OFF,SW3 : ON
4) Power ON the PLC.
Boot the files specified for the memory card to the program memory.
After completion of boot, write the program memory contents to the standard
ROM.
5) Upon completion of the automatic write to standard ROM, the BOOT LED and
ERR. LED flicker and the High Performance model QCPU, Process CPU or
Redundant CPU is placed in a stop error status.
6) Power OFF the PLC.
7) Remove the memory card, and set the DIP switches for valid drive of the High
Performance model QCPU, Process CPU or Redundant CPU to the standard
ROM setting.
• Standard ROM •••••SW2 : ON,SW3 : ON
8) Power ON the PLC.
When the PLC is powered ON, data are booted from the standard ROM to the
program memory and actual operation is enabled.
