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: If you set the Property Type of a Live Value MetaProperty to Integer, and use it on a MetaClass, the Property Value of every instance of the Metaclass will be of type Guid (as well as the column of the related tables and views in the database). When you link a Live Value DataPoint to an instance and read the value via the Live Value Server the value will be expected to be of type Integer. If you add this MetaProperty to a MetaDefinition in ACM, the transfered value (to the clients) will also be of type Integer.
