• Fallback is used when there is no specific logic before the point. It is used as a default value that you can change indefinitely calling the SET action.
• When there is an internal logic in the BOS prior to the point (or in the controller if it's Bacnet), the inputs are used from in9 to in16.
• You can override the logic for a certain duration. The logic can it self invoke the Auto action to release your override on certain event.
• The emergency override is let available to the local Facility Manager to override your own override. So use with caution the Emergency Override since there is no higher level. (The FM can still change the value by setting a new value with Emergency Override action from the supervisory interface)

Output definition

The output of a point will contain three different parts:

• The value itself: a primary value like boolean, numeric, string or enumeration.
• The status. See Linksper statuses for more information
• The active input

The active input will indicate which input is actively reported to the output.

• The format is as follow "@ <level>"
• Level range goes from 1 to 1, with 1 being the highest priority.
• Level 17 is identified by the key "def".

Linksper will merge the status and the active input into the same field (through the API or the connector).

Additional notes

A point is a little more complex that the representation given above., there are additional features to calculate the output value from the inputs such as

• The presence of extensions that can include an algorithm and alter the active input value and the output status.
• The conversion applied to the read value

This is internal behavior to the BOS and do not alter a third party understanding of the exposed data.
