Count Nodes in Policy Designer

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

The following example illustrates how you can use a Count node in the policy model to determine if any Measurement Location readings were recorded within the last week. Consider the following nodes and connections.

In this example, a Collection Filter node is used to filter the readings associated with the Measurement Location node to only the readings that occurred within the last week. The Count node is then used to calculate the number of readings that occurred. The following image shows what the Properties window for the Count node looks like.
