If the method is absolute , the value of the selected variable is compared
directly with the thresholds at the end of the sampling interval. If the
method is
delta , the selected variable value of the last sample is subtracted
from the current value, and the difference is compared with the thresholds.

If the first sample (after this entry becomes valid) is greater than or equal
to rthreshold and direction is equal to
rising or rising-falling , a single
rising alarm is generated. If the first sample (after this entry becomes
valid) is less than or equal to fthreshold and direction is equal to
falling or
rising-falling , a single falling alarm is generated.
