Node Types

There are many different node types that will aid you in building your Driver Model.

These node types are:

• Numeric – A value to be used in the application;
• Asset Parameter – A value linked to an asset in the Asset Library;
• Time series – A numeric value that has a different value over a certain time interval in the application;
• Calculation – Performs a user defined calculation;
• Prior Value – Obtains the value of a node from the previous time period;
• Node Reference – Links to another node on another page;
• Label – A text Label that can be used to app explanatory text to the driver model;
• Image – An image that can be added to the driver model for extra information;
• Background Image - A background image to give context to the driver model; and
• Datasource - Used to reference data from datasources in the driver model.

Now that we have covered the basics of driver models we are ready to begin understanding the different nodes, how to connect them to create flows and build models and systems.

To do this we will use very simple examples which demonstrate a node’s capabilities.

Parameter Groups

A parameter group is used to arrange node results into named output tables. By default, node values that are published to results will appear in the “appoutput_vw” table. By specifying a parameter group, these node values can be added into either a single or multiple output tables.

Parameter group names are added to multiple output tables separated using a comma delimiter. For example, a node could be added to parameter groups “test1” and “test2” by specifying “test1,test2” in the node’s paramater groups field.
