BUTTON ACCESS LEVEL DESCRIPTION
Select Operator
This key is used to enter the slot numbers and the minimum and maximum
Y-Axis values of each parameter to be trended. Pressing this key places a yel-
low 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 "" ENTER key. A dialog box is displayed
permitting data entry.
Data Point Slot
# (1-6)
Operator
Use the SELECT key as described above and enter the slot number from the
Common Slots Screen or Master Slot Number List 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)
Operator
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 param-
eter 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)
Operator
Only displayed if the associated slot number is not zero. This is the maxi-
mum 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 appro-
priate 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
is selected 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.
