Network Management Objects

CAUTION: Normally, most of the network management objects appear transparent to the

user. In other words, the parameters and objects used for network management are not normally
viewed or changed as part of device configuration.

The network management objects in the Logix 3400IQ digital positioner FBAP are listed in the
following paragraphs, although most, (if not all) of these objects are not directly user-configured.

Network Management Information Base (NMIB)
The NMIB contains various objects that are associated with network management operation. Table
8.28 lists the NMIB object dictionary. The groups of network management objects (along with
their index starting numbers) are included in the NMIB for the Logix 3400IQ digital positioner. The
numbers in parenthesis indicate the number of objects.

Virtual Communications Reference (VCR) Objects
The objects listed above contain parameters which define network management operations. These
operations include communications between applications in different field devices (or field devices
and operator interface). In order for this communication to take place, a communications relationship
must be set up using the network management objects and parameters. The parameters for this
communication relationship are stored in a Virtual Communications Reference (VCR) object.
