Data Contextualization

Data contextualization is implemented as models in
FactoryTalk Edge Gateway
. Models help align data to reflect the specific scenario needing analysis. Having aligned data adds resolution and accuracy to the analysis.
FactoryTalk Edge Gateway
 offers three options for data contextualization:
  • Information models
  • FactoryTalk Smart Object
     instances
  • Device Discovery Model
An information model is a framework that allows building relationships at the OT layer as pertaining directly to the OT assets and system attributes. Information models allow for the consideration of the overall operational aspects and their organization in reference to the operational hierarchy. Use the configured data sources to build information models.
FactoryTalk Smart Object
 instances are created in the
Studio 5000
 application environment and are imported into
FactoryTalk Edge Gateway
 via
Studio 5000 Logix Designer
 project files (.acd). A
FactoryTalk Smart Object
 is an extension of the base Logix tag with additional configuration properties. These user-defined configuration properties allow for additional data analysis.
FactoryTalk Smart Object
 instances also provide high-speed data collection with time synchronization and are based on the configuration properties and information model hierarchy. When used with
FactoryTalk Smart Object
 instances,
FactoryTalk Edge Gateway
 offers contextual resolution of high-speed data with time synchronization.
The object-based methodology of
FactoryTalk Smart Object
 instances provides these advantages:
  • Common data across the system
  • Reuse and library management at the automation layer
  • Automatic use by the information layer
  • Contemporary foundation for application development
FactoryTalk Smart Object
 instances are supported in Logix firmware revisions 28.00 or later.
FactoryTalk Smart Object
 instances are automatically discovered from offline Logix project files (.acd) when using an EtherNet/IP driver for data collection.
FactoryTalk Smart Object
 instances organize the data to collect from data sources. After configuring data sources that contain
FactoryTalk Smart Object
 instances, the
FactoryTalk Smart Object
 models become available in
Models
.
FactoryTalk Smart Object
 instances are not editable from
FactoryTalk Edge Gateway
. Modify
FactoryTalk Smart Object
 models in the project for the controller.
Device Discovery Model (Auto-Discovery and Model) enables the user to discover all the known devices and bring them into
FactoryTalk Edge Gateway
 for modeling and egress mapping. Models are created automatically based on the devices that are discovered. User is provided with a list of known device types (based on profiles) where they can select one or more known device types.
FactoryTalk Edge Gateway
 discovers all instances of selected devices and inserts all values accessible in the device into the
FactoryTalk Edge Gateway
 namespace whether or not they're in the profile.
