Create Engineering Item from Functional Item with Data

Prerequisite

• Open Engineering Item Grid.

• Open Functional Item Grid.

• The ‘Engineering Tag’ is used to ‘Engineering Item’ mappings window itself to configure mappings. For example, P&ID is considered as source and PFD as destination though we have mapping defines as PFD as source & P&ID as destination:

  Use cases for Class Mappings

  • You select a centrifugal pump, and the mappings window contains mappings between functional pump and engineering pump. In this case, the application starts to traverse through the tree to find is there any mapping which matches the parent of centrifugal pump and in this case, it finds pump and applies the mapping on the pump to the centrifugal pump.

  • You select a pump, and the mappings are between functional pump and engineering pump. In this case, the application finds the mappings and applies the mappings.

  • You select a pump, and the mappings are between functional pump to engineering centrifugal pump. In this case, the data propagation fails as it cannot find the mapping. As the centrifugal pump is a child of pump.

  • You apply the class mappings when both from side and to side matches with actual type of functional pump and engineering pump respectively.

    Use cases for Attribute Mappings

  • You can map attributes between functional pump and engineering pump, functional pump to a part of engineering pump, part of functional pump to part of engineering pump or part of part of engineering pump to the nth level parts. As shown in the screen shot of mappings.

  • You can map an attribute directly to the attribute of engineering pump or part of engineering pump when it is mapped to part of the pump the application creates the part and then propagates data on to the attribute of the part and it creates the parts when the association type is either can have or has part association. The propagation of data can be done till the nth part of the engineering pump.

  • Cases where the attribute values fail to propagate: You have done a mapping from part of functional pump to engineering pump or its parts and the part on the functional pump does not exists “This throws an error message why and which attribute data is not propagated”. When you have a mapping from functional pump to part of engineering pump and the application fails to create the part on the engineering pump or in other words when the relation between the part and the engineering pump is a reference association.

  • All the active case data value can be propagated from functional pump to engineering pump or even to its parts.

    

To create an Engineering Item (ENGITE) from a Functional Item (FUNITE)

1. On the FUNITE grid, select an item, for example, P1.

   

2. On the Simulation tab in the Engineering Items area, select Create.

   

   To display the New Tag window.

   

3. Click Create.

   An ENGITE with data is created and linked to the pump.

   

4. Open Item Attributes for the pump ENGITE.

   

5. Search for Item Attributes and Values, for example, for Pressure difference.

   The result displays the SIMITE's pump pressure and the available value.
