4.3.2 Switch Operation at the Time of Writing Program

This section explains the switch operation to be performed after a program is written using
GX Developer.
(1) When writing program with CPU module set to "STOP"
(a) To set to RUN status with device memory data cleared
(b) To set to RUN status with device memory data not cleared (held)
(2) When a program is written while CPU module is running
(online change)
No operation is needed for the RUN/STOP switch and RESET/L.CLR switch of the
CPU module.
At this time, the device memory data are not cleared.
1) Move the RESET/L.CLR switch to the RESET position once and return it to the
original neutral position.
2) Set the RUN/STOP switch to RUN.

* 1: When a program was written to the program memory during boot operation, also write the
program to the boot source memory.
If the program is not written to the boot source memory, the old program will be executed at the
next boot operation.
* 2: When online change is performed in the ladder mode, the program changed online is written to
the program memory.
When performing boot operation, also write the program to the boot source memory after online
change. If the program is not written to the boot source memory, the old program will be executed
at the next boot operation
For details of the boot operation, refer to the manual below.
