Creating an algorithm
Algorithms are formulas created on a wire sheet that enable calculations, where the framework can combine real-time and historical
data to produce values and analyze trends (time series).
Prerequisites: All objects are tagged, hierarchies created, and relationships established.
- In the station’s Nav tree, expand , and double-click Algorithms.The Algorithm Manager opens to the Database view.
- To group algorithms, create a folder by clicking New Folder at the bottom of the manager and supplying a descriptive name.
- Do one of the following
- To create a new algorithm, click New, select the number of algorithms to add, and click OK.
- To edit an existing algorithm, select it in the Database table and click Edit (or double-click the row in the table).
The New or Edit window opens.
- Give the algorithm a name, make any changes to the default properties and click OK.
The framework requires data policies for these algorithm properties:
- Aggregation – defines how to combine current values from multiple data sources.
- Rollup – defines how to combine the multiple values contained in a single interval of a trend.
- Min and Max interval – some data may have limitations that establish the acceptable minimum and maximum period to use for rollups. For example, heat and cooling degree days should not have an interval of less than one day.
The algorithm and properties display as a row in the Database table.
