settings
The
BLOCK
input blocks the
OBS_PR_ACT
output, which then disables the maximum
value calculation of the Statistics recorder module. If the trigger mode is selected
"Periodic" or "Continuous" and the blocking is deactivated before the next
observation period is due to start, the scheduled period starts normally.
Statistics recorder
The Statistics recorder module provides readily calculated three-second or ten-
minute values of the selected phase to the percentile calculator module based on
the length of the active observation period. If the observation period is less than
one day, the three-second average values are used. If the observation period is one
day or longer, the ten-minute average values are used.
