6.12 Writing in Program during CPU Module RUN
When the High Performance model QCPU is in the RUN status, you can write programs or
files in any of the steps shown in Table6.27.
POINT
Refer to the following manual for online change (order of write to control system
and standby system, whether tracking can be executed at execution of online
change, etc.) when the Redundant CPU is used.

6.12.1 Online change in ladder mode
(1) Writing data in the circuit mode during RUN Status
Writing data in the circuit mode during RUN is a function to write a program during the
CPU module RUN status.
The program can be changed without stopping the process in CPU module program
by performing writing data in the circuit mode during RUN status.
