Summary0005360: AliasName Aggregating Server conformance unit - verify removal of AliasName and Category
Description

When a server connects to an aggregating server its Aliases are merged. When it disconnects action must be taken.

In addition to all other requirements:

  1. When all servers that have added a specific Alias have disconnected the Alias should be removed (i.e. as long as one server remains that added an Alias, the Alias is not removed). When an Alias is removed a ModelChanged event is triggered.

  2. When all Aliases have been removed from a category (other than the ones predefined by OPC), the Category should be removed (i.e. as long as one Alias remains the Category is not deleted). When a Category is removed a ModelChanged event is triggered.

  3. When an Alias is added/merged a ModelChangedEvent is triggered

  4. When a Category is added/merged a ModelChangedEvent is triggered

Question: If the aggregating server has its own configuration tool for CRUD operations on Aliases, should that tool override the requirements defined by OPC? e.g if a server is connected and has added Alias "Foo", can that Alias be forcibly removed by the config tool?
