Glossary

Original Ć June 1990 CE4.2:CL6211

Discrete Output (DO)

A PROVOX point type. A DO point generates a single discrete value,

referred to as the set point.

DO Acronym: Discrete Output

Download To transfer configuration information from a configuration device to other

devices of a process control system.

EAROM Acronym: Electrically Alterable ReadĆOnly Memory

EDAS Acronym: Extended Data Acquisition System

Electrically Alterable ReadĆOnly Memory (EAROM)

A type of semiconductor memory device, electrically erasable and

reprogrammable, that is used primarily for readĆonly information.

Electromagnetic Interference (EMI)

The general category of electrical noise induced by radio frequency and

magnetic, electrostatic, or capacitive coupling.

Electrostatic Damage (ESD)

Deterioration of integrated circuits due to high levels of static electricity.

Symptoms of ESD include degradation of performance, device

malfunction, and complete failure.

EMI Acronym: Electromagnetic Interference

Engineering Units (EU)

The units of measurement for an analog process variable. Possible

examples are gallons per hour, degrees Celsius, and pounds per square

inch. The low (0 percent) and high (100 percent) engineering unit limits

define the anticipated range of the variable. For example, low and high

engineeringĆunit values of 50 and 1550 might define a range for degrees

Fahrenheit. In this example, the span would be 1500 degrees; each

percent would equal 15 degrees.

Engineering Units Descriptor

The name of the units an engineering units value represents. Possible

examples include MTRS for meters, LB/SQIN for pounds per square inch,

and DEGSCEL for degrees Celsius.

Engineering Units High Value (EUHV)

A floatingĆpoint number that represents the upper limit of the input range

of an analog input value.
