Documentation of parent class DynamicsFunctionBlock:
Abstract parent class for all Dynamics function blocks.

Function block used indicator. true = use of function block is enabled false = use of function block is disabled. Default: False
Documentation of parent class IdentifiedObject:
This is a root class to provide common identification for all classes needing identification and naming attributes.
- DiagramObjects
The domain object to which this diagram object is associated. Default: “list”
- mRID
Master resource identifier issued by a model authority. The mRID is globally unique within an exchange context. Global uniqueness is easily achieved by using a UUID, as specified in RFC 4122, for the mRID. The use of UUID is strongly recommended. For CIMXML data files in RDF syntax conforming to IEC 61970-552 Edition 1, the mRID is mapped to rdf:ID or rdf:about attributes that identify CIM object elements. Default: ‘’
- name
The name is any free human readable and possibly non unique text naming the object. Default: ‘’
- description
The description is a free human readable text describing or naming the object. It may be non unique and may not correlate to a naming hierarchy. Default: ‘’
- energyIdentCodeEic
The attribute is used for an exchange of the EIC code (Energy identification Code). The length of the string is 16 characters as defined by the EIC code. References: Default: ‘’
- shortName
The attribute is used for an exchange of a human readable short name with length of the string 12 characters maximum. Default: ‘’
