General Information
Introduction
MAS is able to present data both with
fi
gures and diagrams. Momentary data, max and
min values and recordings over a long time period can be viewed. With the operator panel,
only momentary data and max and min values are presented. To view other logged data, a
computer with a web browser is required.

Database
The system measures and stores data continuously in a cyclic memory on a
fi
rst in,
fi
rst
out basis. The highest resolution is one second, which means that the system measures
and stores measurement results each second. To keep the amount of data within the limits
of the memory capacity, each new data value replaces an old. The highest resolution of
data is transformed into average values in steps: each minute a minute average value is
formed, each hour an hour average value and so on. The result is that the further back
you wish to study data, the lower the resolution.
This table shows the data that is stored for each analog channel in the trend diagrams
