I_AcsiCommonAttributeClass

Objects that implement this interface are at the fifth hierarchical level (or higher) of the IEC 61850 data model and are referred to as data attributes (DA). Data attributes are the smallest object units. They contain detailed information such as data object values. Multiple data attributes are often grouped into larger units (common data classes, CDC), for example binary counter reading, BCR. There are also attributes that contain further attributes (e.g. AnalogValue, RangeConfig or Unit). Such attributes are referred to as "constructed attributes". This can result in further, deeper hierarchical levels. The TwinCAT Telecontrol Configurator generates function blocks for these levels, which are derived/extended from FB_AcsiCommonAttributeClass. All function blocks derived from FB_AcsiCommonAttributeClass automatically have the interface referred to above implemented by default.

For objects that implement this interface, the same services can be used as for the I_AcsiCommonDataClass interface (e.g. GetDataValues, SetDataValues).
