OPC HDA server aggregate types
You do not create
AggregateTypes objects directly; instead,
when you connect an OPC HDA client to the server, the
property is automatically populated with available aggregate types for that
|getDescription||Get description of OPC HDA aggregate type or item attribute|
|getIDFromName||Translate OPC HDA aggregate type or item attribute name to numeric identifier|
|getIDList||Get all aggregate type or item attribute IDs|
|getNameList||Get all aggregate type or item attribute names|
AggregateTypes objects have no generic user-visible properties.
Instead, each available aggregate type is created as a property. For example, if the
server supports the
TIMEAVERAGE aggregate type, the
AggregateTypes object stored in the
Aggregates property of a client connected to that server has
a property named
TIMEAVERAGE with its value set to the numeric ID
of that attribute.
