Sum Nodes in Policy Designer

The Properties window for a Sum node contains the items that are described in the following table.

The following example illustrates how you can use a Sum node in a policy model to determine the total value of the Measurement Location readings that were taken within the last week. Consider the following nodes and connections.

In this example, the Collection Filter node is used to filter the readings associated with the Measurement Location node to only the readings that were recorded within the last week. The Sum node is then used to calculate the total value of these readings. The following image shows what the Properties window looks like for the Sum node.
