*1: Set the flow size to 0 for memory assignment.
If a program transfer is performed by specifying the flow size, the message "Cannot execute: Operation error" is displayed, and
a peripheral unit remain as WRITE occupied. In this case, either cancel the occupy state from LADDER EDITOR of the
peripheral unit or by re-entering the CPU power.
