Piping data defined in Smart P&ID can be transferred to PDS® using the Smart P&ID to PDS Piping Data Transfer capability. The ability to transfer PDS P&ID data to PDS 3D is documented in the PDS documentation and is therefore not covered here.

Piping System Schematic and Physical Representations

Although both Smart P&ID and PDS describe the same plant, a one-to-one correspondence between the components in the two models does not always exist. Smart P&ID to PDS piping data transfer is essentially the transfer of data from the Smart P&ID segment table to the PDS piping segment table, pdtable_12_xx.

The conceptual definition of a segment is the same in both applications, however that does not mean that there is a one-to-one correspondence between these two tables. For example, the number of segments is not the same, even if the Smart P&ID and PDS piping model exactly match from a design point of view. This situation is caused by the different drafting practices of Smart P&ID and PDS. For example, drains are shown as macro symbols on the Smart P&ID drawing. However, drains are branch segments in the PDS model. Also, process connections to instruments are recorded as instrument signal lines in the Smart P&ID database, but on the PDS side, process connections are piping segments.

Due to these differences, the data transfer process requires establishing a logical link between the corresponding segments. This linkage can either be in the form of interactive input from the PDS designer, who can choose a piping segment in a drawing by selecting it, or be a combination of attributes defined as unique criteria in the SPTransferOpt file. For more information on attribute mapping, see Mapping Attributes.

Data Transfer in the Real World

When you model a new line in PDS, use the Data from P&ID option, and then select a Smart P&ID segment. By doing this, you are establishing the logical link. After this link is established, future data transfers can be fully automated.

However, as with most plants, there is a time when Smart P&ID drafting and PDS modeling continues in parallel. The P&IDs are changing while piping modeling continues in PDS. When the designer models a particular pipeline, the equivalent Smart P&ID segments might not yet exist in the Smart P&ID database, creating a significant amount of piping that does not have the associative link between Smart P&ID and PDS.  This is just one example of how creating and updating links is an ongoing process rather than a one-time effort.
