Live Value MetaProperties are specialized MetaProperties and must be used when accessing 3rd party values via the UBIK® Live Value Server integration. They can be used on every MetaClass and will help to manage a Reference to a Live Value Datapoint for every single instance of the MetaClass.
The type of a Live Value MetaProperty is always Guid. The properties created based on these MetaProperties will hold a reference to a Live Value DataPoint instance.
PropertyType
The configured property type is used to define the data type of the real time value (in the 3rd party system) and not the type of the MetaProperty itself.
Example
A property type of a Live Value MetaProperty is configured to be integer. If this Live Value MetaProperty is used on a MetaClass, the property values (of the according property) of each instance of this MetaClass will always be of type Guid. Same applies of course for the columns of the corresponding database tables and views.
If a Live Value DataPoint is linked to an instance (via the Live Value property) the read value, via the Live Value Server, is expected to be of type Integer.
If this MetaProperty is included within the ACM the published value (to the clients) will also be of type Integer.
