speed execution type programs, it is not necessary to be conscious of online change of low
speed execution type programs.

Basic
Redundant Universal
The Basic model QCPU, Redundant CPU and Universal model QCPU cannot change the
UD
program files during RUN by the PLOADP, PUNLOADP or PSWAPP instruction.
Note6.22
Note6.22 Note6.22
In the low speed execution type program, data are written online in the END
processing of the next scan after completion of all the program execution.
Note the execution of low speed execution type program is suspended during online
change.

instruction Note6.22 Note24
If the online change is executed while the PLOADP, PUNLOADP or PSWAPP
instruction is executed, the processing will enter into a stand-by status for the online
change. If the online change is executed while the PLOADP, PUNLOAD or PSWAPP
instruction is executed, the execution of the instruction is delayed until the online
change is executed.
