Alert Attachment
Alerts are atttached to assets in your ARDI database.
There are several different methods of attachment…
Direct / Asset Attachment
In this case, your alert is attached directly to a single, named asset.
Type Attachment
Your alert will be attached to every asset of a particular type.
This is usually used when there's an alert (or an alert threshold) particular to a single type of asset in your ARDI system.
Property Attachment
Your alert will be attached to every asset that shares all of a particular set of properties.
This is useful if you have different assets with similar control limits, but they don't share a type. They're most commonly used for control limits and speed thresholds - for instance, by attaching an out-of-control alert to any asset that has both a target and an actual speed.
Relationship Attachment
This attaches an alert to the nominated asset, plus every asset found down-stream from it along a specific relationship.
This is useful when you want to deploy an alert across a set of assets, particularly if you're looking for discontinuities, leaks or other asset-to-asset changes.
