FIGURE 41 - TREND SETUP SCREEN

OVERVIEW
This screen is used to configure the Trend screen. The
parameters to be trended are selected from the Com-
mon Slots screen or common slots master list and
entered as slot numbers for Data Points 1 through 6.
The Y-Axis minimum and maximum values for each
parameter are entered as "Data Point Min" and "Data
Point Max" for Data Points 1 through 6. The interval at
which all the parameters are sampled is selected as the
"Collection Interval".

Collection Interval
Access Level Required: OPERATOR
Selects the interval at which the trending parameters
are sampled. There are 450 data points displayed
across the X-Axis of the graph. Each point represents
the value of the parameter at that time. The user selects
the time interval between these points. This is called
the "Data Collection Interval", or the interval at which
the data for the parameter is sampled. This interval is
programmable over the range of 1 second to 3600 sec-
onds (1 hour), in one second increments. The selected
interval not only determines the sample interval, but
also the full screen time display. The full screen time
display is a result of the selected interval in seconds,
multiplied by the 450 data points.
• For example: If the data collection interval is pro-
grammed for 900 seconds, the parameter would
be sampled every 900 seconds, with the last 112.5
hours (4.7 days) of data viewable on the screen.
Therefore, the selected interval is a compromise
between resolution and full screen time display.
