Glossary
Term. duplex
Can be half or full. Full-duplex is simultaneous, bi-directional data.
Term. duty cycle
The percentage of available time a feature is in an active state.
For example,
if the CR6 is programmed with 1 second scan interval, but the program
completes after only 100 millisecond, the program can be said to have a 10%
duty cycle.
Term. earth ground
A grounding rod or other suitable device that electrically ties a system or
device to the earth. Earth ground is a sink for electrical transients and
possibly damaging potentials, such as those produced by a nearby lightning

Earth ground is the preferred reference potential for analog voltage
measurements. Note that most objects have a "an electrical potential" and the

be different.
Term. engineering units

Term. ESD
Electrostatic discharge
Term. ESS
Environmental Sensor Station
Term. excitation
Application of a precise voltage, usually to a resistive bridge circuit.
Term. execution interval
See
scan interval
(p. 507).
Term. execution time
Time required to execute an instruction or group of instructions. If the
execution time of a program exceeds the
Scan()
Interval
, the program is
executed less frequently than programmed.
Term. expression
A series of words, operators, or numbers that produce a value or result.
Term. FFT
Fast Fourier Transform.
A technique for analyzing spectrum data.
