instruNet World Plus

Data Acquisition and Control Software
for Use With instruNet Data Acquisition Systems

instruNet World Plus is a reasonably
priced yet powerful and easy-to-use
data acquisition software program
for Windows 95/98/NT/2000/XP
(not Macintosh). 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
hardware.

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).

Custom Instrument Front Panel - Figure 1

Run Feedback/Control
Loops

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
feedback/control, waveform
generation, math, file, hardware,
and user interface functions as

instruNet World Plus
Includes Digitize Direct To
Excel Software

instruNet World Plus includes the
Digitize Direct To Excel program,
which populates an Excel (Version
>= 8.0, Office >= 97) spreadsheet,
(as shown in Figure 2) while
digitizing.

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 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.

Create Buttons - Figure 6

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…".

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.

Print Waves and Text on
Hard Copy Printer

Print text and waveforms directly to
a printer.

Display Time
of Day Under Waves

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

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

Create
Popup
Menus

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.

Copy the Setup of One
Channel to Many Channels

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.
