• Choose [Online]
memory to ROM...] on GX Developer, and write to the standard ROM the
files written to the program memory. (
4) Program execution
Resetting with the RUN/STOP/RESET switch of the Basic model QCPU boots
the program from the standard ROM.
5) Check for normal boot completion
Whether the boot is normally completed or not can be checked by the special
relay (SM660) status.
Refer to Appendix 1 for the special relay.
Perform the following operation using GX Developer to stop boot run and execute
operation by the parameter program written to the program memory.
1) Format the program memory.
2) Choose [Online] [Write to PLC (Flash ROM)]
to ROM...].
(Parameters and sequence program data in the standard ROM are cleared.)
3) Write parameters and sequence program data to the program memory.
1) Files stored into standard ROM
Before executing boot run, store the following files into the standard ROM.
*1
• Parameter
• Intelligent function module parameter
*2
• Program
• Device comment
• Device initial value
* 1 : Must be stored into the standard ROM.
* 2 : Any of the sequence program, ST program and SFC program is necessary.
2) Online change during boot run
If online change is made to a program in the program memory during boot run
from the standard ROM, the change is not updated on the program in the boot
source standard ROM.
Hence, write the program to the standard ROM (
the CPU module is put in a STOP status.
3) When program memory contents change at power OFF
If the sequence program written to the program memory changes when the
PLC is powered ON or reset, boot run may be in execution.
Refer to "(1)(c)Operation to stop boot run" in this section, and stop the boot
run.
