* 1: A file cannot be written during RUN if the trailing edge instruction is included in the write program
file when [Trailing edge instructions are not executed] is set in the option menu "instruction
operating setting at writing during RUN" of GX Developer.
However, if a write program is the SFC program, the file can be written during RUN even if the
trailing edge instruction is included in the write program file.
(For the operation of setting [Trailing edge instructions are not executed] in the "instruction
operating setting at writing during RUN" of GX Developer, refer to Section 6.12.3.)
* 2: A program file can be written to the program memory during RUN in the Universal model QCPU.
(b) For the Universal model QCPU
A file can be written during RUN regardless of whether empty area exists enough
to write a program file.
The scan time increases when the file is written during RUN.
For increased scan time, refer to Section 11.1.3.
No access can be made from an instruction in a program to the file during online
change.
The instruction to make access to a file during online change will not be executed.
Do not execute file write in RUN simultaneously from multiple locations.
Doing so may erase program file contents.
