Assuming that a device is configured with a DNP address equal to 3 (three), these are examples of N1, N2, N3, and N4 parameters, in N1.N2.N3.N4 format.

Digital Input 100, Object 1 Variation 2: 3.1.102.100 (configured as a static object)
Digital Input 100, Object 2 Variation 2: 3.1.202.100 (configured as an event)

In the previous example, both Tags reference the same variable (Digital input 100), but the first Tag remains continually requesting the current value (polling), while the second one only receives notifications when the point changes its value. In addition, as an Event the timestamp of the change from the device is kept. In the Static mode, on the other hand, as there is no timestamp, it is generated with the computer's time at event's arrival.
