Displays available instances of OEXPVPH (24) with a number of measurements per
instance. These measurements indicate whether values are out of the measuring range
(ERROR) and if the overexcitation function has caused a trip (TRIP). The thermal
status as a percentage of the trip level and the calculated time to trip are among the
other outputs available here.
