Selecting Calculated; Selecting Point Range; Selecting Point Tag; Selecting Decimal Fix - Siemens SIREC D Handbuch

B. Hi Peak Point Type -
Types with a Point Range of Hi Peak keep track of
the highest data of a given point. This data is stored
until some form of reset occurs. When the data is
reset, the Hi Peak Point data is printed on the Chart
along with the current time and the time the peak
value occurred if Reset print is enabled.
When Calculated Point Types of Hi Peak, Lo
Peak, or time Average point ranges are re-
set, the new value will be the current base
point value at the time of reset.
C. Lo Peak Point Type -
Types with a Point Range of Lo Peak keep track of
the lowest data of a given point. This data is stored
until some form of reset occurs.
When the data is reset, the Low Peak Point data is
printed on the chart along with the current time and
the time the peak value occurred if reset print is
enabled.
D. Time Average -
a Point Range of Time Average calculate a
continuous average of the measured or processed
value of a selected point. The result is a weighted
average of the present reading and the previous
average value. This value can be used to smooth
out noisy or erratic signals and to attenuate the
effects of sudden transitions.
