Add a data type to an information model
Add a data type to a FactoryTalk Smart Object information model. Set the basic collection properties to describe how the FactoryTalk Smart Object collects data.
- Select a node, selectAdd
, and select the data type you want to add.
You can add regular and writeback instances of the following data types:- DINT
- LINT
- REAL
- STRING
TheAdddialog box appears.FactoryTalk Smart Objectinstances - 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 theStudio 5000 Logix Designerproject that contains the configuration information for theFactoryTalk Smart Object.
- Source value tag (optional)orTarget tag (Optional)/: Location where the data is gathered or where it is sent. Writeback data types use target tags, regular data types use source value tag.
- 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 theFactoryTalk Smart Objectappears.
- Insert at end: Location at the end of a routine where theFactoryTalk Smart Objectappears.
- For non-writeback data types, set data collection parameters:
- On parent or periodic: When this checkbox,On programmatic, andOn valuecheckboxes 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, theFactoryTalk Smart Objectis 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).
- SelectAdd.
A new rung appears in the ladder logic. The data type
FactoryTalk Smart Object
appears in the FactoryTalk Smart Object
tree. Provide Feedback
