Additional ControlNet Network Information

ControlNet Application

Objects

In addition to the standard adapter class ControlNet core objects, the CGCM

unit also supports these application specific objects:

• Identity Object

• Assembly Object

Data Types

The ControlNet and Logix controller data types used by the CGCM unit

assembly objects are shown in the table below.

All data is stored in Little Endian format (least significant byte first). This is

assumed for all data and structure formats described in this document that do not

have the storage format specifically defined.

All integers and double integers are displayed in decimal.

Identity Object (class code 0x01)

The Identity Object is used to provide identification information about the

device.

Identity Class Instance (instance 0)

Instance 0 of any ControlNet object represents the class itself.
