The NIFB process that must be running in the background for you to
use your USB-8486, PCMCIA-FBUS, or PCI-FBUS interface to
communicate between the board and the Fieldbus.

Node

Junction or branch point in a circuit.

O

Object

An element of an object dictionary.

Object Dictionary

A structure in a device that describes data that can be communicated
on the Fieldbus. The object dictionary is a lookup table that gives
information such as data type and units about a value that can be
read from or written to a device.

Octet

A single 8-bit value.

OD

See

Object Dictionary.

OPC

OLE for Process Control.

Output parameter

A block parameter that sends data to another block.

P

Parameter

One of a set of network-visible values that makes up a function block.

PC

Personal Computer.

PCMCIA

Personal Computer Memory Card International Association.

PD

Proportional Derivative.

Physical device

A single device residing at a unique address on the Fieldbus.

PID

Proportional/Integral/Derivative. A common control function block
algorithm that uses proportions, integrals, and derivatives in
calculation.

PN

Probe Node.

Poll

To repeatedly inspect a variable or function block to acquire data.

Port

A communications connection on a computer or remote controller.

PR
