====Example - Comparing Actual to Target====

This Agent has two inputs - the Actual value and the Target value - and uses the [[Differential|differential]] algorithm to flag if they have drifted apart from one-another.

We want to raise an alert if they differ by more than 1.5 units.

In most cases, you'll want to use a [[Type Attachment|type]] or [[Property Attachment|property]] attachment.
