This topic describes the primary flow of activities when you use Smart Instrumentation to design a plant to be run and controlled using the Emerson DeltaV plant automation and control system.
In an integrated environment, after retrieving DCS vendor data, under certain circumstances
the software can create two identical CS tags, this occurs when you have selected
the Create CS Tags Automatically check box in the Instrument Profile. After retrieving the DCS vendor data, in the
To Do List you will see the Create tasks for the CS tag and the instrument. Running
these tasks creates the CS Tag and the instrument but because the Instrument Profile
has the Create CS Tags Automatically check box selected, an identical CS tag is also created and is visible in the Domain
Explorer. To stop this from happening you must clear the Create CS Tags Automatically check box before running the Create tasks.

Before publishing or retrieving DeltaV data for the first time, make sure that you perform the prerequisite activities indicated: retrieving DeltaV definitions, updating your plant design, and if appropriate, associating Foundation Fieldbus device types.
-
You may perform any of the stages of this flow of activities multiple times during the project life cycle.
Retrieving DeltaV definitions is a prerequisite for both publishing and retrieving DeltaV data. The DeltaV item definition documents that you download and retrieve in Smart Instrumentation constitute the engineering library of DeltaV objects - the DeltaV DCS (Distributed Control System), Foundation Fieldbus, CHARM, S-Series, Conventional, and HART elements, and entries for supporting tables such as Manufacturer, Model, and so forth.
After you complete the process of designing your DeltaV- compatible plant in Smart Instrumentation, use this procedure to publish (export) the required data for accurate and efficient DeltaV configuration. The software publishes a partial set of the Smart Instrumentation, including data such as the DeltaV configuration, I/O assignment, instrument tags, and so forth (the process does not export specification data, for example).
After retrieving the published data in DeltaV, validate and, if necessary, reconcile the data with the DeltaV database.
Use this procedure to retrieve (import) data from DeltaV. The software retrieves controllers and slots and, if specified in the published .xml file, Foundation Fieldbus devices.
If using fieldbus tags, after retrieving the DeltaV data, but before running any
To Do List tasks, you must make associations between device types for Foundation Fieldbus
or HART instruments with instrument manufacturers, and Smart Instrumentation instrument types. For more information, see Associate Device Types for DCS Vendors.
