implied valve position or pressure

(IVP)

The output of a primary control algorithm

(PCA) or a smart field device. The IVP

either determines how much to open a

valve actuator, which moves to a position,

or determines the pressure of a

transducer. Note that if the IVP is

modified by a station function or FST

after being computed by the PCA, the

valve output and the IVP will not be the

same.

import

1. For ENVOXr software: moving CDV

files into the configuration database.

2. For Recipe Manager software:

another database to the current

database.

INAC

1. Abbreviation: Inactive

2. Acronym: Increase To Close

INC CLO

This remote detail display parameter

(DDP) a ttribute, 10:INC CLO, shows

FIELDVUE variable 74, increase to close,

as a yes (increase close) or no (increase

open). This tunable DDP is used to

enable or disable the output signal

inversion (based on actuator type) from a

PROVUEr or Operator Workplace

console.

IND

Abbreviation: Indicator

indicator

1. An instrument that graphically shows

the value of a variable.

2. A visual readout of a measurement,

condition, or operating mode of a device,

or an alarm to get someone’s attention.

indirect control point (ICP)

A regulatory controller point type which is

composed of a set of analog or discrete

values. These values may be displayed

at a console, but are not used to directly

control a process.

indirect measurement

A procedure performed by some smart

field deivces that converts a

measurement sent in one unit of

measurement, such as pressure, to

another unit of measurement, such as

gallons. For example, a differential

pressure transmitter used to measure

gallons might actually be reading

pressure. The transmitter sends the

number of gallons in terms of pressure

and the system converts th e pressure to

gallons. This action is considered an

indirect measurement.

industrial control architecture (ICA)

A group of basic principles that guided

the design of several IBM computers.

The acronym ICA is an IBM mark.

.in file

Input sample file.

information stream

The first stream in a CDV file.

initialize

The process of bringing the software to a

state where it accepts a configuration

from the ENVOX database, or accepts a

self-download; typically, part of boot up.
