CJC

Acronym: Cold Junction Compensator

class

A group of G2 objects that have the

same attributes. For example, all sensors

are of the class sensor. Classes are

organized into a hierarchy in which each

class inherits the attributes of its superior

class, but may have additional attributes

of its own.

See Hierarchy of Classes and Superior

Class.

click

To press and release a mouse button

(usually the primary mouse button) while

the pointer is in a particular location.

client

An application program written for the X

Window System.

client application

A program or tightly related programs

which run on a client workstation.

client’s company name

The client’s company name is presented

as the client within the database

information portion of the Open Database

dialog box in the Instrument Information

Systemt (IIS) Client software.

client/server

The relationship between the client and

the server. Under the client/server

relationship, some of the work in

processing data is offloaded from the

server to the client to implement the

system resources.

closed loop control

Automatic feedback control in which the

manipulated variable is adjusted in

response to changes in controlled (and

sometimes disturbance) variables based

on a specific algorithm.

CMD

Abbreviation: Command

CMOS

Acronym: Complimentary Metal Oxide

Semiconductor

CMPTR

Abbreviation: Computer Mode

CND -CC21 through CND-CC30

A group of FSTs in the ENSTRUCT

structure that stores conditions and

variables. These FSTs should be grouped

by point type (DCD,DI, AI, and so on) and

spread evenly among the 10 LCPs so

that the load is distributed evenly among

conditions that use variables and

conditions which do not. Similar

applications should be handled similarly

for consistency.

CNSL

Abbreviation: Console

CO

Acronym: Current Output

COG

Abbreviation: Center Of Gravity

Cohen and Coon tuning

Refers to a closed loop tuning procedure.

cold jun ctio n compensator (CJC)

1. A transmitter variable (CJC Comp.

Temperature) available from a

Rosemount 3044C Temperature

Transmitter.

2. A Rosemount 57-ohm resistance

temperature device (RTD) that generates

sensor cold junction compensation for a

thermocouple.
