5 SUPPORTED OBJECT CLASSES
Any DeviceNet equipment is modeled as a set of objects. The objects are responsible for defining the function
that each device will have. In other words, depending on the objects the device implements, it may be a
communication adapter, an AC/DC drive, a photoelectric sensor, etc. Mandatory and optional objects are
defined for each Device Profile. The CFW500 frequency converter supports all mandatory classes defined for
the AC/DC Device Profile. It also supports Manufacturer Specific classes. The following sections present
detailed information about these classes.
5.1 IDENTITY CLASS (01H)
Provides general information about the device identity such as: VendorID, Product Name, Serial Number, etc.
The following attributes are implemented:
Table 5.1: Identity Class instance attributes
5.2 MESSAGE ROUTER CLASS (02H)
Provides information on the explicit message router object. This class does not have any attribute implemented
in the CFW500.
5.3 DEVICENET CLASS (03H)
This class is responsible for maintaining the configuration and the state of the physical connections of the
DeviceNet node. The following attributes are implemented:
Table 5.2: DeviceNet Class attributes
Revision of the DeviceNet Object Class Definition upon which the
implementation is based
Table 5.3: DeviceNet Class instance attributes
Information about allocation byte
5.4 ASSEMBLY CLASS (04H)
This class is responsible for grouping several attributes in only one connection. Only the attribute Data (3) is
implemented in the CFW500 (Table 5.4).
Table 5.4: Attributes of the instances of the Assembly class
Data contained in the assembly object
The Assembly class contains the following instances in the CFW500:
