(b) Online change in boot operation
1) SRAM card, ATA card
When a program in the program memory is written in the RUN status (
updated to the program in the boot source SRAM card or ATA card.
2) Standard ROM, Flash card
Even if data are written to a program in the program memory in the RUN status, the change is not updated to
the program in the boot source standard ROM or flash card.
Therefore, write the same file whose program was written to the program memory to the standard ROM or
flash card by Write to PLC (Flash ROM). (
(c) Maximum number of settable boot files
Set the maximum number of settable boot files in the Boot file tab of the PLC parameter dialog box so that it
may be the same with the number of files storable to the program memory.
However, the number of boot files reduces by 1 when:
• a heading is set, or
• the parameters set in the Boot file tab of the PLC parameter dialog box and stored in the standard ROM or
memory card is booted.
(d) Boot operation when the ATA card is used
When data are booted in the following status, the processing time of maximum 200ms may be required per 1K
step (4K bytes).
• Boot from the ATA card
• Boot from the standard ROM with the ATA card mounted
(e) When data in the program memory are changed after the CPU module is powered off
and then on or is reset
If the program memory data are changed after the sequence program is written to the program memory and the
CPU module is powered off and then on or is reset, a boot operation may be active.
While the BOOT LED on the front of the CPU module is on, the boot operation is active. Refer to (4) in this
section and stop the boot operation.
(f) Size after a boot from the memory card
The size unit of a file stored in each memory differs between the memory card and the program memory.
( Section 5.4.4)
Therefore, note that files transferred from the memory card to the program memory differ in memory capacity
between before and after the transfer.
(g) Program written to the memory card
Set the programmable controller type (model name of the CPU module) for the program written to the memory
card (program set in the Boot file tab) and the model name of the CPU module to be booted to the same.
