R
range The region between the limits within which a quantity is measured,
received, or transmitted expressed by stating the lower and upper range
values.
Real-Time Database
(RTDB) An in-memory snapshot of all tags in the system.
real-time trend A plot of data (values versus time) that is updated as each new point is
acquired in the Real-Time Database.
reentrant execution Mode in which calls to multiple instances of a subVI can execute in parallel
with distinct and separate data storage.
representation Subtype of the numeric data type, of which there are signed and unsigned
byte, word, and long integers, as well as single-, double-, and
extended-precision floating-point numbers, both real and complex.
resizing handles Angled handles on the corner of objects that indicate resizing points.
RTDB See Real-Time Database.
S
sampling period The time interval between observations in a periodic sampling control
system.
SCADA Supervisory Control and Data Acquisition.
sensor A device that produces a voltage or current output representative of some
physical property being measured, such as speed, temperature, or flow.
sequence local A terminal that passes data between the frames of a Sequence Structure.
Sequence structure Program control structure that executes its subdiagrams in numeric order.
Commonly used to force nodes that are not data-dependent to execute in a
desired order.
shift register Optional mechanism in loop structures used to pass the value of a variable
from one iteration of a loop to a subsequent iteration.
