TR4.0:PROVOXRevision A — April 1997

complimentary metal oxide

semiconductor (CMOS)

A family of digital integrated circuits that

use transistors operating in a push-pull

mode to carry out logic functions. A

CMOS usually is capable of low-powered

operation.

Computer/Highway Interface

Package (CHIP)

APROVOXr software product that allows

user-written programs to interact with the

PROVOX system. There are d ifferent

CHIP versions, so that several types of

computers can be the host computer.

computer integrated manufacturing

(CIM)

A philosophy of industrial design and

manufacture that uses computer-based

systems to integrate and coordina te

engineering functions, business

functions, and factory operations.

computer interface unit (CIU)

A set of cards that acts as a protocol

converter to the CCON, BCON, or

CCOMP, to interface with the PROVOXr

data highway.

computer mode (COM)

A point operating mode: the setpoint can

be changed only by a unit operation,

group point, CHIP program, or FST.

concurrent batch structure

Product flow between two units that are

running at the same time.

concurrent task

The ENSTRUCT software function that

can run as many as four tasks

concurrently with a continuous unit such

as a totalizer or jacket valve. The

ENSTRUCT software includes standard

subroutines for totalizers, differential gap,

jacket valves, and flow check.

concurrent task active flag

The Boolean variable used by the

ENSTRUCT software to confirm that the

concurrent task FSTs are running (have

not been turned off). This flag is

referenced in the fail expression. The

location of this variable is BV 3 of a batch

unit.

condition

A TRUE/FALSE evaluation used by the

ENSTRUCT software of a predetermined

process state, such as the valve is closed

or the level is greater than 90%.

Conditions are defined in a condition

table and accessed by their index

number.

conditionals

PROVUEr console display elements that

change color or present messages based

on a change in a point attribute.

condition index number

In the ENSTRUCT software: a unique

number assigned to each condition. This

number contains the controller number,

the LCP number, and the status bit

number in the following format:

CCLLSS, where

HCC is the controller number

HLL is the LCP number (01 through 20)

HSS is the status bit number (01 through

16)
