POSC Specifications: Epicentre Version 3.0 | Logical Data Model |
A description of the behavior of fluids inside a product flow network unit. This behavior is described between two PFNU ports within a PFNU.
- initial_port (M: pfnu_port(initial_port_for))
- This designates the port that is the initial port for the internal path between two product flow network unit ports. Each pfnu_internal_behavior_model must be the path from one pfnu_port.
- terminal_port (M: pfnu_port(terminal_port_for))
- This designates the port that is the terminal port for the internal path between two product flow network unit ports. Each pfnu_internal_behavior_model must be the path to one pfnu_port.
- description (O, I: ndt_comment) (C117)
- A remark or comment about the instance. Inherited from e_and_p_data.
- identifier (O: ndt_identifier) (C049)
- The identifier of the PFNU internal distribution model.
- instance_create_date (O, I: ndt_date_tod) (C126)
- This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
- instance_creator (O, I: ndt_identifier) (C126)
- This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
- last_updated (O, I: ndt_date_tod) (C126)
- This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
- last_updated_by (O, I: ndt_identifier) (C126)
- This records the person or application making the update to this instance. Inherited from e_and_p_data.
- source (O, I: ndt_identifier) (C126)
- The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
- data_collection (I, V: SET[0:?] data_collection_content(collection_part)) (C020)
- Indicates the data collections that include this instance of E and P data. Each pfnu_internal_behavior_model may be a member of one or more data_collection_content. Inherited from e_and_p_data.
- derived_interest (I, V: SET[0:?] derived_interest_makeup(interest_for)) (C071, C122)
- These are the ownership fractions for business associates of this object. Each pfnu_internal_behavior_model may be referenced by one or more derived_interest_makeup. Inherited from object_of_interest.
- document_information_content (I, V: SET[0:?] document_information_content(e_and_p_data)) (C136)
- These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each pfnu_internal_behavior_model may be included in one or more document_information_content. Inherited from e_and_p_data.
- graphical_element (I, V: SET[0:?] graphical_element(depicted_object))
- Specifies one or more graphical elements which are depicting this data item. Each pfnu_internal_behavior_model may be depicted by one or more graphical_element. Inherited from e_and_p_data.
- involving_activity (I, V: SET[0:?] object_activity_involvement(involved_object)) (C056)
- This are the activity involvements which affect the object. Each pfnu_internal_behavior_model may have involvements with one or more object_activity_involvement. Inherited from object_of_interest.
- pty_flow_equivalent_length (V: SET[0:?] pty_flow_equivalent_length(pfnu_internal_behavior_model))
- Each pfnu_internal_behavior_model may have a property of one or more pty_flow_equivalent_length.
- pty_pressure_change (V: SET[0:?] pty_pressure_change(pfnu_internal_behavior_model))
- Each pfnu_internal_behavior_model may have a property of one or more pty_pressure_change.
- pty_pressure_drop_gradient (V: SET[0:?] pty_pressure_drop_gradient(pfnu_internal_behavior_model))
- Each pfnu_internal_behavior_model may have a property of one or more pty_pressure_drop_gradient.
Local rules:
- Abstract supertype:
- Each PFNU_INTERNAL_BEHAVIOR_MODEL must be instantiated as one of its subtypes. These subtypes are: horizontal_pipe_flow_model, vertical_tubing_flow_model
- Different Related Instance
-
Each PFNU INTERNAL BEHAVIOR MODEL must have a different instance of initial_port than it has for terminal_port.
- Same Related Instance (C112)
-
The initial_port and the terminal_port of the PFNU INTERNAL BEHAVIOR MODEL must belong be ports for the same instance of PRODUCT FLOW NETWORK UNIT.
