Virtual instruments (VIs) contain three main components-the
front panel, the block diagram, and the icon and connectorpane.
The front panel is the user interface of a VI and specifies
the inputs and displays the outputs of the VI.
The block diagram contains the graphical source code
composed of nodes, terminals, and wires.
Use the
Tools palette to create, modify, and
debug VIs. Press the
Shift key and right-click
to display a temporary version of the
Tools palette at the location of the cursor.
Use the
Controls palette to place controls and
indicators on the front panel. Right-click an open space onthe front panel to display the
Controls palette.
Use the
Functions palette to place VIs and
functions on the block diagram. Right-click an open space onthe block diagram to display the
Functions palette.
Use the
Search button on the
Controls and
Functions palettes to
search for controls, VIs, and functions.
All LabVIEW objects and empty space on the front panel and
block diagram have associated shortcut menus, which youaccess by right-clicking an object, the front panel, or the
block diagram.
Use the
Help menu to display the
Context
Help window and the
LabVIEW Help , which
describes most palettes, menus, tools, VIs, functions, andfeatures.
Select
Help>>Search the LabVIEW Bookshelf to
display the
LabVIEW Bookshelf , which you can
use to search PDF versions of all the LabVIEW manuals and
Application Notes .
You build the front panel with controls and indicators,
which are the interactive input and output terminals of theVI, respectively.
Control terminals have a thicker border than indicator
terminals. To change a control to an indicator or to changean indicator to a control, right-click the object and select
Change to Indicator or
Change to
Control from the shortcut menu.
The block diagram is composed of nodes, terminals, and
wires.
The broken
Run button appears on the toolbar to
indicate the VI is broken. Click the broken
Run button to display the
Error list window, which
lists all the errors.
Use execution highlighting, single-stepping, probes, and
breakpoints to debug VIs by animating the flow of datathrough the block diagram.
Tips and tricks
Operating
Frequently used menu options have equivalent keyboard
shortcuts. For example, to save a VI, you can select
File>>Save or press the
Ctrl-S keys. Common keyboard shortcuts include the following:
Ctrl-r
Runs a VI.
Ctrl-e
Toggles between the front panel and block diagram.
Ctrl-h
Toggles display of the
Context Help window.
Ctrl-b
Removes all broken wires.
Ctrl-f
Finds VIs, globals, functions, text,
or other objects loaded in memory or in a specified listof VIs.
To increment or decrement numeric controls faster, use the
Operating or
Labeling tools to
place the cursor in the control and press the
Shift key while pressing the up or down arrow
keys.
You can disable the debugging tools to reduce memory
requirements and to increase performance slightly. Select
File>>VI Properties , select
Execution from the top pull-down menu, and
remove the checkmark from the
Allow Debugging checkbox.
Wiring
Click the
Show Context Help Window button on
the toolbar to display the
Context Help window. Use the
Context Help window to
determine which terminals are required. Required terminalsare bold, recommended connections are plain text, and
optional connections are dimmed.
Press the spacebar to toggle the wire direction.
To move objects one pixel, press the arrow keys. To move
objects several pixels, press the
Shift key
while you press the arrow keys.
To cancel a wire you started, press the
Esc key, right-click, or click the terminal where you started
the wire.
Use the tip strips that appear as you move the
Wiring tool over terminals.
Display the connector pane by right-clicking the node and
selecting
Visible Items>>Terminals from the
shortcut menu.
You can bend a wire by clicking to tack the wire down and
moving the cursor in a perpendicular direction. To tackdown a wire and break it, double-click.
1. Tack Down a Wire by Clicking,
2. Tack and Break the Wire by Double-clicking
Editing
Use the following shortcuts to create constants, controls, and
indicators:
Right-click a function terminal and select
Create>>Constant ,
Create>>Control , or
Create>>Indicator from the shortcut menu.
Drag controls and indicators from the front panel to
the block diagram to create a constant.
Drag constants from the block diagram to the front
panel to create a control.
To duplicate an object, press the
Ctrl key
while using the Positioning tool to click and drag aselection.
To restrict an object's direction of movement horizontally
or vertically, use the
Positioning tool to
select the object and press the
Shift key
while you move the object.
To keep an object proportional to its original size as you
resize it, press the
Shift key while you drag
the resizing handles or circles.
To resize an object as you place it on the front panel,
press the
Ctrl key while you click to place
the object and drag the resizing handles or circles.
To replace nodes, right-click the node and select
Replace from the shortcut menu.
To display the block diagram of a subVI from the calling
VI, press the
Ctrl key and use the
Operating or
Positioning tool to
double-click the subVI on the block diagram.
To display the front panel of a subVI from the calling VI,
use the
Operating or Positioning tool to
double-click the subVI on the block diagram. You also canselect
Browse>>This VI's SubVIs .
After you type a label, press the
Enter key
to end text entry.
To add items quickly to ring controls and
Case structures, press the
Shift-Enter keys after each item. Pressing
Shift-Enter accepts the item and positions
the cursor to add the next item. Refer to
Making Decisions in a VI for more
information about
Case structures.
To copy the color of one object and transfer it to a
second object without using a color picker, use the
Color Copy tool to click the object whose
color you want to copy. Use the
Coloring tool
to click the object to which you want to apply thecolor. You also can copy the color of one object by using
the
Coloring tool and pressing the
Ctrl key.
Select
Edit>>Undo if you make a mistake.
To create more blank space on the block diagram, press the
Ctrl key while you use the
Positioning tool to draw a rectangle on the
block diagram.
Debugging
When single-stepping, use the following keyboard shortcuts:
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️
_Adnan
define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
