(c) Maximum number of boot files that can be set
The maximum number of boot files that can be set in the boot file setting of the
PLC parameter dialog box should be the same as the number of files that can be
stored into the program memory.
However, in the following cases, the number of boot files decreases by 1 for each.
• When a heading is set
• When the PLC parameters (set in the boot file setting) stored in the standard
ROM/memory card are booted
(d) Boot run executed when ATA card is used
When boot run is executed in either of the following states, a maximum of 200ms
may be taken per 1k step (4k bytes) at a boot.
• When boot is executed from the ATA card
• When boot is executed from the standard ROM with the ATA card installed
(e) When data in the program memory are changed at power OFF ON or reset
If the data in the program memory are changed when the programmable controller
is powered OFF ON or the reset operation of the CPU module is performed
after sequence programs are written to the program memory, it may be
considered that the boot operation is still active.
The boot operation is active if the BOOT LED on the front of the High
Performance model QCPU, Process CPU, Redundant CPU, and Universal model
QCPU is on.
Refer to (4) in this section and stop the boot operation.
(f) Capacity after boot from memory card
The size unit of the file stored in each memory differs between the memory card
and the program memory. ( Section 5.4.4)
Therefore, note that the file transferred from the memory card to the program
memory changes in memory capacity between before and after the transfer.
(g) Program written to memory card
The PLC type (the model of the CPU module) of programs written to the memory
card (programs set in the boot file settings) and the model of the CPU module
targeted for boot operation must be same.
