(4) The execution timing of low speed execution type program
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.
1) : RUN write command of scan execution type program
2) : RUN write execution of scan execution type program
3) : RUN write command of the low speed execution type program
4) : RUN write execution of the low speed execution type program
(5) Online change during execution of PLOADP, PUNLOADP or PSWAPP
instruction
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.

Note6.21
Since the Basic model QCPU, Redundant CPU and Universal model QCPU cannot use low
speed execution type programs, it is not necessary to be conscious of online change of low
speed execution type programs.
