instruNet World Plus is a reasonably
priced yet powerful and easy-to-use
data acquisition software program
for Windows ≥XP SP2, Vista, 7 or
8. It enables one to digitize, plot,
control, analyze, and save to disk
A/D, D/A, and digital I/O data from
instruNet hardware. Additionally,
it enables one to define their own
instrument front panel with buttons,
popup menus, edit fields, dynamic
text, text editor regions, and
waveform graphs, as illustrated in
Figure 1 on this page.
instruNet World Plus is programmed
with a simple script language that
can define tasks such as control
loops. For example, one can type
“Dac1 = OnOff (Ain1, 3)” to define
D/A #1 as a function of A/D #1.
instruNet World Plus software adds
valuable features to the standard
instruNet World (not Plus) software
which is included with instruNet
Generate Analog and Digital
Output Waveforms
Define an analog or digital output
channel mathematically (e.g. sine
wave, square wave, pulse train, etc)
that updates in real-time (e.g. every
100 ms).
Run Feedback/Control
Define an analog or digital output
channel as a real-time function of
analog and/or digital input channels
(e.g. PID control, on/off control, etc).
Create a Custom Instrument
Create buttons, popup menus,
edit fields, dynamic text fields, text
edit regions, and pages to build a
custom application program.
Powerful Script
Programming Language
instruNet World Plus is programmed
with a simple BASIC-like script
language that provides many

instruNet World Plus
Includes Digitize Direct To
Excel Software
instruNet World Plus includes the
Digitize Direct To Excel program,
which populates an Excel ≥V11.0
(Microsoft Office ≥2003, Excel
≥2003) spreadsheet, (as shown in
Figure 2) while digitizing.
Direct to Excel - Figure 2
Print Waves and Text on
Hard Copy Printer
Print text and waveforms directly to
a printer.
Display Time
of Day Under Waves
Front panel popup menus allow the
selection of one of several choices
in a list, as illustrated in Figure 3.
One line of script code reads or
sets the position of the popup (i.e.
1 refers to the upper-most item,
2 the one below it, etc). The
position, label, and list options
are easily set.
Popup Menu - Figure 3
Create Edit Fields
Front panel edit fields allow one to
select, view and edit segments of
text, as shown in Figure 4. One line
of script code reads or sets the text
in the same way one would read
or write to a string variable. The
position, label, and initial text are
easily set.
Edit Field - Figure 4
Create Buttons - Figure 6
Display waveforms relative to
the Date and Time of Day. For
example, in Figure 8, the first grid
corresponds to June 11, 2003,
6:12pm + 31 seconds. Without
instruNet World Plus waves are
always displayed relative to the start
of digitization.
Time of Day Under Waves - Figure 8
Create Text Editor Pages
In instruNet World Plus, a “page”
is similar to a “sheet” in Microsoft
Excel. One clicks on a tab at the
bottom of the window (note the tabs
in Figure 7) to show a different set
of front panel items (e.g. popup
menus, text editor, edit fields, etc).
For example, in a simple case,
one might create a page called
“Help” that when selected, displays
documentation on how to use the
instrument. Figure 7 shows 2 user
defined pages, labeled “Page 1” and
“Page 2”, where Page 1 is currently
selected and contains a text editor
region that shows the text “One can
type text here…”.
Adjust Horizontal Scale
While Digitizing
A front panel popup menu (refer
to Figure 9) adjusts the displayed
horizontal scale (i.e. time per plotted
horizontal division) while digitizing.
In the standard version of the
instruNet World software (not Plus),
this is set automatically, or via the
Record Setup dialog.
Adjust Time of Day While
Digitizing - Figure 9
Test Editor Page - Figure 7
Create Dynamic Text Fields
Front panel dynamic text fields allow
one to view non-editable segments
of text, as shown in Figure 5. One
line of script code sets the text in
the same way one would write to a
string variable. The position, label,
and initial text are easily set.
Dynamic Text Field - Figure 5
Create Buttons
One can easily create buttons that
execute script code when pressed
(e.g. “Button 1” shown in Figure 6.)
The position, label, and script text
are easily set.
Copy the Setup of One
Channel to Many Channels
Save Waves to Excel
instruNet World Plus provides
a menu command called “Save
Waveforms To Excel” that saves all
waves into one large text file that
can be loaded by Microsoft Excel,
post-acquisition, where each wave
is given its own column.
Setting up many channels manually
can be somewhat laborious.
instruNet World Plus automates
this with a command that copies
the setup of one channel (e.g. to a
thermocouple, strain gage, etc) to
multiple other channels.

Digitize in Background
While Working in Other
Digitize and implement feedback/
control loops in instruNet World
while working in other application
programs. For example, one can
type in a Microsoft Word window
while instruNet World Plus digitizes
and controls outputs. Also, one can
minimize the instruNet World Plus
window (i.e. click on window title bar
upper right corner “_” icon to place
minimized instruNet World Plus
window on desktop application bar)
while it operates in the background.
Examine Waveform
Values With a Cursor
Use the mouse to move
a waveform cursor while
numerically viewing the time
and waveform value at that
cursor position, as illustrated
in Figure 10.
