CIP Object
Object Model
In the CIP (Common Industrial Protocol) system, each device is modeled as a group of “Objects.” An Object
abstractly represents a related group of the device’s data values.
When accessing the device from the outside, access an Object.
An Object represents the abstracted device function, processing, and the resulting data.
A request from the outside of Object, such as Read Data, is called “Service.
Data belonging to the Object is called “Attribute.
The actual entity of Object is called “Instance” or “Object Instance.
When Object is generalized, it is called “Class.” For example, “Japan” is one of Instances (Object Instances) of
Class “Nation.
