Scaling
The value produced by a data group can be Scaled using a Formula or limit Conditions.
 |
Formula scaling provides three operators with values.
Example: An item contains the flow rate in gallons/minute. To calculate the total flow in MGD perform an average on the item value and then scale with *1440/1000000.
Example: An item contains the temperature in Fahrenheit. To convert to Celsius scale, use the formula
-32*5/9.
Condition scaling provides up to three Limits that provide up to three ways the value can be scaled. The scaling supported are:
Specific Value
Column Value
Column Value that has an applied Formula
Example: When an item value is below 0.001, display the text negligible otherwise show the value.
Example: When an item value is below 100, display blank otherwise scale the value by 1000.
Example: A digital item contains the state of a pump. When the value is less than 0.5 display OFF, otherwise ON.
Example: An item contains the temperature of an oven. Display LOW, MEDIUM, and HIGH at specified temperature thresholds.
