Models
Use models to organize data into a hierarchy. Associate models with applications or data destinations.
Build models by staging tags, and then associating the tags to a node or property. Use parent and child nodes to form a hierarchy of information elements.
These are guidelines for models:
- There is a maximum of 30 models per gateway.
- There is a maximum of 500 parent nodes per model.
- There is a maximum of eight layers per model.
When
FactoryTalk Smart Object
instances are configured in a Studio 5000 Logix Designer
controller, connecting to that controller by importing an .acd file replicates the FactoryTalk Smart Object
model created in the controller. It is possible to view the imported FactoryTalk Smart Object
model from this area; however, FactoryTalk Smart Object
models cannot be edited from the gateway.
TIP:
When using data egress to SQL, the maximum column size is 512 characters. Be sure to create names for models, nodes, and properties that do not exceed 512 characters.
A model ID:
- Cannot exceed 512 characters
- Will be built based on the pathway to the property: ModelName + "." + Node1 "." + Node8 + "." + PropertyName.
