What does Labview stand for?
Laboratory Virtual Instrument Engineering Workbench
-
What is Front Panel?
The interactive interface of a VI, it is composed of switches, slides, meters, graphs, charts, guages, LEDs, and other controls and indicators.
-
Functions palette?
Pallet containing block diagram structures, constants and VIs.
-
Tools palette?
Palette containing tools you can use to edir and debug front panel and block diagram objects.
-
Controls Palette?
Palette containing front panel controls and indicators.
-
Palette?
Menu of pictures that represent possible options.
-
Nodes?
Execution elements of a block diagram consisting of functions, structures, and subVIs.
-
Virtual Instrument?
A program in LabVIEW; so-called because it models the appearance and function of a physical instrument.
-
What color are boolean wires?
Green
-
What color are String wires?
Pink
-
What are numeric data colors?
Blue (int), orange (Double and Long)
-
Data Flow?
Nodes will only exicute when all required data is aquired to exicute the code.
-
G Programming?
Graphical Programming Language.
-
Input/output terminals?
Terminals where data wires link to and from indicators and controls, etc. (Source terninals, Destination terminals)
-
Numeric controls and indicators?
Front panel objects used to manipulate and display numeric data.
-
Wire?
Data path between nodes.
-
Connector?
Part of the VI or node that contains its input and output terminals.
-
Property Nodes?
Allows you to set and get the properties od an object.
-
Operating tool?
Tool used to enter data into controls and operate them. Resembles a pointing finger.
-
Navigation window?
Displays an overview of the active front panel in edit mode or the active block diag.
-
Function?
An exicution element compairable to an operator or statement in other languages.
-
Marquee?
dashed border surrounding selected objects.
-
SubVI?
A subroutine that can be used by a top level VI.
-
Top-Level VI?
A VI at the top of the VI hierarchy.
-
Indicator?
A front panel object that displays an output.
-
Control?
A front panel object for entering data into the VI or subVI.
-
For Loops:
Two terminals: The count (input terminal) and iteration (an output terminal). Foors loops run a set number of times.
-
Count terminal?
Number of times you want the loop to execute.
-
Iteration?
Counter that counts the times the loop has exicuted.
-
-
While loop:
Has two terminals: The conditional terminal (an input) and the iteration terminal (an output) While loops run until false.
-
Conditional terminal?
Conditional test for the loop to dertimine if the loop is true or false. The terminal condition is either Stop if true or Continue if true.
-
Structure?
A program control element such as a Sequence, Case, For loop or While loop.
-
Case Structure?
Similar to an IF-Then-Else statement. It executes only one of its subdiagrams baised on inputs.
-
Coercion?
Automatic numeric conversion of a data element by Labview.
-
Formula Node?
A node that executes formulas enterd as text.
-
Tunnels?
Allows wired to be connected from outside a structure to objects inside a structure.
-
EMR:
- Coil takes 75ma to run.
- Pickup voltage 9v.
- operating voltage 12v.
-
Optio:
- LED takes 60ma.
- C to E = 150ma
- Surge voltage 7500v
- Max f = 19MHz
-
USB-6009:
- Max sink(open collector)/active drive(push pull) current = 8.5ma
- Max sample rate= 48KHz
- 8 analog inputs 0-7
- Max unit draw = +5 @ 200ma
- Normally uses RSE (Referenced Single Ended Voltage Signals connect pos to An input and neg to grnd)
- Digital ports = 12. ( no need for a pull up)
- 512 bytes of RAM
- 13 bit out/ 12 bit in.
