Function
PLS

turns OFF the device in any other case the execution command is turned OFF ON (i.e., at
ON ON, ON OFF or OFF OFF of the execution command).
When there is one PLS instruction for the device designated by during one scan, the
specified device turns ON one scan.
See Section 3.9 for the operation to be performed when the PLS instruction for the same

instruction, the PLS instruction will not be executed again even if the switch is set back to
RUN.
