POINT
(1) If the start condition is established again during the order monitoring period,
monitoring returns to the 1st condition establishment wait state and order
monitoring continues.
(2) If two or more conditions are established simultaneously, the conditions are
considered to have been established in the specified order, so the trigger will
not occur when detecting an abnormal pattern.
