Automatic Writing To Standard Rom - Mitsubishi Melsec-Q Series User Manual

4.3.5 Automatic writing to standard ROM

The High Performance model QCPU, Process CPU and Redundant CPU allows data in the memory card to be written
into the standard ROM automatically.
For details, refer to the following.
Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals)
(1) Procedures for automatic write to standard ROM
Automatic writing to the standard ROM is performed with the following procedures.
(a) Operation with GX Developer (setting automatic writing to standard ROM)
1) Check the "Auto Download all Data from Memory card to Standard ROM" in the PLC parameter boot file
setting.
Set the parameter and program to be booted at the "Boot file" setting section.
(Set the "Transfer from" to "Standard ROM".)
2) Store the set parameters and programs to be booted in the memory card.
(b) Operations on CPU module (automatic writing to standard ROM)
1) Power off the programmable controller.
2) Insert the memory card that contains the parameters and programs to be booted onto the CPU module.
3) Set the DIP switches on the CPU module so that the valid parameter drive is matched with the memory card
to be installed.
• When a SRAM card is installed: SW2 : On, SW3 : Off
• When a Flash card/ATA card is installed: SW2 : Off, SW3 : On
4) Power on the programmable controller.
• Boot the file specified in the memory card into the program memory, and write the program in the
memory to the standard ROM after completion of the boot.
5) The BOOT LED will flash when automatic write to standard ROM is completed, and the CPU module will be
in the stop error status.
6) Turn off the programmable controller.
7) Remove the memory card, and then set the valid parameter drive to the standard ROM with the CPU
module's DIP switches.
• Standard ROM: SW2 : On, SW3 : On
The parameters and programs will be booted from the standard ROM to the program memory when the
programmable controller is turned on to enable actual operations.
