  • An event is raised when the tag's alarm state is constant for the set time period (the configured tag excursion delay period).

  • When the tag's state changes, the new state is monitored, and the time period starts again.

Example one - Baseline

Polling frequency = 1 minute

Excursion delay = 0 minutes (No excursion delay has been configured)

!discrete - baseline

A new event is raised every time the tag's alarm start changes. The open event closes when the tag moves into a neutral state.

Example two

Polling frequency = 1 minute

Excursion delay = 2 minutes

1 discrete - example 1

The tag's state needs to remain constant for over two minutes before an event is trigged because the excursion delay is two minutes. In this example, none of the states remain constant for over two minutes, so no event is trigged.

Example three

Polling frequency = 1 minute

Excursion delay = 2 minutes

2 discrete - example 2

Events are raised after the tag's state has been constant for over two minutes. The two minute excursion delay period starts again when the tag's state changes.

Example four

Polling frequency = 1 minute

Excursion delay = 2 minutes

3 discrete - example 3

The Boiling state changes after two minutes, so no event is raised. The two minutes excursion delay period starts again when the Fire state is triggered. The open event closes when the tag moves into a neutral state.

Example five

Polling frequency = 1 minute

Excursion delay = 2 minutes

4 discrete - example 4

Events are raised after the tag's state has been constant for over two minutes. The two minute excursion delay period starts again when the tag's state changes. The active event closes when the tag moves into a neutral state.
