Industrial Ethernet (IND)
: OBJECT MODEL
The Object Model is the logical organization of attributes (parameters) within classes
(objects) and services supported by each device.
Objects are broken down into three categories:
Required Objects , Vendor Specific
Objects and Application Objects .
•
Required Objects are classes that must be supported by all devices on
Industrial
Ethernet (IND)
. The BIS M-626 has six Required Objects.
•
Vendor Specific Objects are classes that add attributes and services that do not fit
into the Required Objects or Application Objects categories. The BIS M-626 has two
Vendor Specific Objects.
•
Application Objects are classes that must be supported by all devices using the same
profile. An example of a profile is a Discrete I/O device or an AC Drive. This ensures
that all devices with the same profile have a common look on the network.
