Abbrev.
A set of objects and services that provide management of a
NM
device's communication system.
Part of the device software that operates on network
NMA
management objects.
A collection of objects and parameters comprising configura-
NMIB tion, performance and fault-related information for the
communication system of a device.
Entities, such as blocks, alert objects, trend objects,
parameters, display lists, etc.
Definitions and descriptions of network visible objects of
a device. Various object dictionaries are contained within a
OD device. The dictionaries contain objects and their associated
parameters which support the application in which they are
contained.
A value or variable which resides in block objects.
A standard control algorithm. Also refers to a PID function
PID
block.
Provides services that coordinate the operation of various
SM
devices in a distributed fieldbus system.
Part of the device software that operates on system manage-
SMA
ment objects.
A collection of objects and parameters comprising configura-
SMIB tion and operational information used for control of system
management operations.
A coded value that qualifies dynamic variables (parameters)
in function blocks This value is usually passed along with
the value from block to block. Fully defined in the FF FBAP
specifications.
Similar to a function block, but performs functions specific
XD to the device transducer, including measurement and
calibration.
A defined communication end-point. Fieldbus commu-
nications can primarily only take place along a active
communications 'path' that consists of two VCR endpoints.
VCR For example, to establish communications between a trans-
ducer AO block and another function block, a VCR must be
defined at the transducer block and a VCR must be defined at
the function block between the two function blocks.
A logical grouping of 'user layer' functions. Function blocks
VFD are grouped into a VFD, and system and network manage-
ment are grouped into a VFD.
