This key is used to enter the slot numbers and the
minimum and maximum Y-Axis values of each param-
eter to be trended. Pressing this key places a yellow
box around Data Point 1 Slot Number. Use the ▲ and
▼ navigation keys to place the box around the value of
Data Points 1 through 6 to be changed. With the desired
value selected, press the ‘4’ (Enter) key. A dialog box
is displayed permitting data entry.
Data Point Slot # (1-6)
Use the SELECT key as described above and enter
the slot number from the Trend Common Slots Screen
of the desired parameter to be trended. The selected
parameter description will be displayed for the Data
Point. Setting this slot number to zero will disable
trending for that particular Data Point. Any or all points
can be disabled.
Data Point Min (1-6)
Only displayed if the Associated Slot Number is not
Zero. This is the minimum value displayed for the
Y-Axis. Selecting a parameter for a Data Point sets
this to the default value, which is the lowest value
allowed for that parameter. It can be changed to a
value that provides a more appropriate resolution for
the parameter being monitored. To change, use the
SELECT key as described above and enter the desired
value. The value must always be set to a value less
than the Data Point Max. Otherwise, a red graph is
displayed on the Trend Screen with the words “TREND
MAX MUST BE > TREND MIN”. If the parameter
selected for this data point is a digital type (on/off),
this value must be set to zero (0). Zero indicates the
OFF state.
Data Point Max (1-6)
Only displayed if the associated slot number is not zero.
This is the maximum value displayed for the Y-Axis.
Selecting a parameter for a Data Point sets this to the
default value, which is the highest value allowed for that
parameter. It can be changed to a value that provides a more
appropriate resolution for the parameter being monitored.
To change, use the SELECT key as described above and
enter the desired value. The value must always be set to
a value greater than the Data Point Min. Otherwise, a red
graph is displayed on the Trend Screen with the words
“TREND MAX MUST BE > TREND MIN”. There are
20 Y-axis divisions. If a MIN-MAX span is selected that is
not evenly divided by 20, the Program will automatically
select the next higher MAX value that makes the span
evenly divided by 20. For example, if 0.0 is selected as
the MIN, and 69.0 as the MAX, the Program will insert
70.0 as the MAX value. If the parameter selected for this
data point is a digital type (on/off), this value must be set
to one (1). One indicates the on state.
