This section explains the switch operation after a program is written using programming tool.
(1) When writing program with CPU module set to "STOP"
(a) To set to RUN status with device memory data cleared
1.
Set 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.
3.
The CPU module is placed in the RUN status (RUN LED: On).
(b) To set to RUN status with device memory data not cleared (held)
1.
Set the RUN/STOP switch to RUN.
2.
The RUN LED flashes.
3.
Set the RUN/STOP switch to STOP.
4.
Set the RUN/STOP switch to RUN again.
5.
The CPU module is placed in the RUN status (RUN LED: On).
(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 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 a program is changed online in the ladder mode, the changed program 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 following.
Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals)
● Before writing a program to the CPU module, perform the following operation.
• Set the system protect setting switch (DIP switch: SW1) of the CPU module to off (not protected).
• Cancel the registered password on programming tool.
● When the CPU module is placed in the STOP status by the remote STOP operation of programming tool, it can be put in
the RUN status by the remote RUN operation of programming tool after program write. In that case, No operation is
needed for the RUN/STOP switch and RESET/L. CLR switch of the CPU module.
● For details of programming tool, refer to the following.
