7.7.12 Boot run method (Writing programs to ROM)

The ROM operation of the AnSCPU corresponds to the boot run of the QCPU. The overview of the boot
run is explained below.
Refer to QCPU User's Manual (Function Explanation, Program Fundamentals) for details.
The Universal model QCPU does not have to perform the boot operation since its program memory is a
Flash ROM.
(The data written to files are not erased even if a battery error occurs.)
However, the Universal model QCPU other than Q00UJCPU, Q00UCPU, and Q01UCPU can perform
the boot operation by using a memory card or an SD memory card.
For the procedure of the boot operation using a memory card, refer to the following:
Procedure 1: Configure the boot file settings.
Set the names and storage destinations of the files to be booted to the program memory in the
Boot file tab of the PLC parameter dialog box of GX Works2.
Procedure 2: Mount the memory card.
Mount the memory card or SD memory card to the CPU module.
Procedure 3: Write data to the memory card.
Write the parameters and programs set in the Boot file tab to the memory card or SD memory
card using GX Works2.
Procedure 4: Execute the program.
Set the RUN/STOP/REAET switch to reset. The BOOT LED turns on after a boot from the
specified memory is completed.
