Table6.18 shows whether online change (files) can be performed or not depending on memory area.
*1: When "Trailing edge instructions are not executed" is selected in "Instruction operational settings for online change/file
online change" in the Options tab of GX Developer, if the program file to be written contains the fall instruction, it cannot be
written in the RUN status.
Note when a program to be written is a SFC program, even if the program file to be written contains the fall instruction, it
can be written in the RUN status.
(For operation when "Trailing edge instructions are not executed" is selected, refer to Section 6.12.3.)
(3) Increase in the scan time
The scan time increases when a program file is written to the CPU module in the RUN status.
For increase in the scan time, refer to Section 10.1.3.
(4) When a file is accessed by a sequence program instruction
An instruction in a program cannot access to the file being written to the CPU module in the RUN status.
If doing so, the instruction will not be executed.
The relevant instructions are as follows:
• PLOADP instruction
• PUNLOADP instruction
• PSWAPP instruction

Do not simultaneously write files to one CPU module in the RUN status from multiple locations.
Doing so may delete program files.
