Locked and Override Status

A common feature of aggregates used in plants are manual or remote (hand icon) and local (key icon) overrides. These two features will display the state of an aggregate when a user issued an override via Niagara or used the override mechanisms of the hardware IO Modules.

To realize these features on the GraphicLibrary widgets two properties are available on that widget:

Name	Type	Default
lockedStatus	boolean	`false`
overrideStatus	boolean	`false`

When one of the properties set to true the respective icon is shown. If both are true the key icon is shown over the hand icon. This overlapping means that although the local override is active someone issued a manual override. Once the local override is released the manual override will be active and a user has to issue the “auto” action.

Locked Status

The locked status shows a key icon meaning the output controlling the aggregate is overridden locally on the hardware Module and no automation or manual override can change something.

Override Status

The locked status shows a hand icon meaning the output controlling the aggregate is overridden manually via the “override” action provided by the ControlPoint.
