Picture 2: Figures
Nmas supports figure calculations in two levels. Levels are defined as
hardware level and software level . Difference between levels is that
calculation of hardware level figures are done immediately when data is
measured. Software level figures are calculated when data is stored to
database. Software level figures can also be calculated anytime after data has
been stored.
Nmas hardware level figures can be related to peak, mean or rms values of
relating data. Software level figures have no limitations. Data in nmas storage
can be manipulated, recalculated and associated to other signals as desired.
Please note that some
software level figures have to be specially added to nmas
and are not included in standard user interfaces.
Warning and Alarm
Nmas warnings and alarms are always related to figures. All figures can have
individual warnings and alarms. As in figures nmas supports two levels of
warnings and alarms. Levels are defined as hardware level and software level.
When using warnings and alarms it is important to notice that only hardware
level warnings and alarms are calculated immediately when data is measured.
When warning or alarm information demand immediate actions they should be
configured as hardware level warnings and alarms.
Nmas hardware level warnings and alarms can be related to peak, mean or rms
values of data.
