Add a REAL data type to an information model

Add a REAL data type to a
FactoryTalk Smart Object
 information model. Set the basic collection properties to describe how the REAL
FactoryTalk Smart Object
 collects data.
To add a REAL data type to an information model
  1. Perform one of these actions:
    • Right-click a node and then select
      New REAL
      .
    • Select a node, select
      Add
       , and then select
      REAL
      .
      The
      Add REAL
      FactoryTalk Smart Object
       instances
       dialog box appears.
  2. Set these basic properties:
    • Name
      : Name of the data displayed in the information model. See Rules for names and backing tags.
    • Backing tag
      : Name of the backing tag in the controller. A backing tag is created in the
      Studio 5000 Logix Designer
       project that contains the configuration information for the
      FactoryTalk Smart Object
      .
    • Source value tag (optional)
      : Location where the data gathers.
    • Program
      : Controller program where the node resides.
    • Routine
      : Controller routine where the node resides.
    • Insert at
      : Location to add a rung in the routine where the
      FactoryTalk Smart Object
       appears.
    • Insert at end
      : Location at the end of a routine where the
      FactoryTalk Smart Object
       appears.
  3. Set these data collection parameters:
    • On parent or periodic
      : When this checkbox,
      On programmatic
      , and
      On value
      checkboxes are clear, data collection for this data value does not occur.
      TIP:
      It is possible to have multiple triggers active at once.
      • Parent
        : When Parent is triggered, the
        FactoryTalk Smart Object
         is also triggered.
      • Periodic
        : Interval in seconds when data is sampled in the source tag.
    • On programmatic
      : Ladder logic that triggers the condition for collection.
    • On value, when the value changes by
      : Data is sampled each time that it changes based on the value in engineering units (positive number).
  4. Select
    Add
    .
    A new rung appears in the ladder logic. The real
    FactoryTalk Smart Object
     appears in the
    FactoryTalk Smart Object
     tree.
