iW PLUS FEATURES
SOFTWARE > INSTRUNET WORLD PLUS SOFTWARE (iW+) >

Below is a list of features available in iW+ that are not available in the free instruNet World (not +) software. For a list of features available in both products, click here.

Create a Custom Instrument
Create buttons, popup menus, edit fields, dynamic text fields, text edit regions, and pages to build a custom application program; as illustrated below.

iW+ includes digitize Direct To Excel software
iW+ includes the Digitize Direct To Excel program, which populates an Excel ≥ 2010 (e.g. Microsoft Office ≥ 2010) spreadsheet, shown below, while digitizing. For details, click here.

Create Popup Menus
Front panel popup menus allow the selection of one of several choices in a list, as illustrated to the right. 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, as described here.

Create Edit Fields
Front panel edit fields allow one to select, view and edit segments of text; as shown to the right. 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, as described here.

Create Dynamic Text Fields
Front panel dynamic text fields allow one to view non-editable segments of text, as shown to the right. 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, as described here.

Create Buttons
One can easily create buttons that execute script code when pressed (e.g. "Button 1" shown on the right). The position, label, and script text are easily set, as described here.

Create Text Editor Pages
In iW+, 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 the illustrations to the right) 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. The above illustration 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 ·". For details on user defined pages, click here.

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 to the right.

Adjust Horizontal Scale While Digitizing
A front panel popup menu adjusts the displayed horizontal scale (i.e. time per plotted horizontal division) while digitizing. In the non-PLUS verison if iW, this is set automatically, or via the Record Setup dialog.

Powerful Script Programming Language
iW+ is programmed with a simple BASIC-like script language that provides many feedback/control, waveform generation, math, file, hardware, and user interface functions as summarized below. For a description of each function, click here. For a summary of the iW+ script programming language, click here.

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 realtime (e.g. every 100ms). For details, click here. For details on maximum I/O rates, click here.

Run Feedback/Control Loops
Define an analog or digital output channel as a realtime function of analog and/or digital input channels (e.g. PID control, on/off control, etc). For details, click here.

Save Waves to Excel
iW+ 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. For details, click here.

Print Waves and Text On Hard Copy Printer
Print text and waveforms directly to a printer. For details, click here.

Display Time of Day Under Waves
Display waveforms relative to the Date and Time of Day. For example, in the above picture, the first grid corresponds to June 11, 2003, 6:12pm + 31 seconds. Without PLUS, waves are always displayed relative to the start of digitization. For details, click here.

Copy the Setup of One Channel to Many Channels
Setting up many channels manually can be somewhat laborious. iW+ automates this with a command that copies the setup of one channel (e.g. to a thermocouple, strain gage, etc) to multiple other channels. For details, click here.

Digitize in Background while Working in other Programs
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 iW+ digitizes and controls outputs. Also, one can minimize the iW+ window (i.e. click on window title bar upper right corner "_" icon to place minimized iW+ window on desktop application bar) while it operates in the background.
