Devices and Interfaces of DIA
dem
- the PC Workshop
DIAdem®, the PC workshop provides solutions for your technical tasks. It is made up of seven components called
devices.
DIAdem® DATA manages data sets. Data can be processed individually, in blocks or in channels.
Data is displayed for overview in data channels; the corresponding data properties are displayed in
sorted table format.
DIAdem -DATA
With DIAdem® VIEW you can view data or “look at it under the magnifying glass.” The Working
area is divided into several axis systems to facilitate viewing. Curve sections can be deleted and
recalculated.
DIAdem®-VIEW
DIAdem® CALC lets you evaluate data mathematically. Each mathematical operation can be
performed with custom parameters or configured with permanent default settings. Individual
calculations are documented in the background in the form of a script.
DIAdem®-CALC
With DIAdem® GRAPH you can document data in presentation format. Represent your
information using graphs, bars, or tables. You c an also embed in ba ckground graphics.
DIAdem®-GRAPH
DIAdem®-DAC
DIAdem®-VISUAL
DIAdem-AUTO
DIAdem® Interfaces
With DIAdem® DAC (Data Acquisition and Control) you can process data online. Measurement
and control tasks are described graphically and are divided into four separate layers: the data
layer, the Packet Processing layer, the control layer and the system layer.
With DIAdem® VISUAL your terminal becomes a real-time display instrument. The wide range of
indicator and input instruments and the capability of linking in images and image sequences allow
you to simulate any number of measurement instruments and situations (real world
instrumentation).
DIAdem® AUTO allows you to automate procedures as Autosequences. Procedures can be
recorded interactively and then run off any number of times, with results that can be accessed by
all the DIAdem
®
devices. DIAdem® user dialogs enable you to intervene interactively while the
Autosequence is runni ng.
DIAdem® has various interfaces for linking external applications: data is exchanged with other
Windows applications via DDE and OLE and with databases via ODBC/SQL. External hardware
drivers (OPC server) can be accessed via OPC. Via the TCP/IP interface, (measured) data can be
exchanged online between DIAdem
®
-PCs within a network. The DLL interface GPI in DIAdem
®
can be used to integrate measurement hardware, data file drivers, commands and variables.

When acquiring data to disk, your application’s file

During the conversion, a “Converting Fil e” box
shows: an animated completion bar, format of the
source and target files, and file paths of the source
and target. The box is usually on screen for only a
moment; however, we can obtain the information
from your application’s Data Destination region,
as mentioned in the following tip.

After the data conversion completes, check the Data Destination area of your application. Certain applications,
such as DaqView, make use of a Data Destination tab. Other applications (such as WaveView), show data
destination after a “Direct to Disk” [or equivalent] button is pressed. Consult your application’s user
documentation as needed.
It is a good idea to write down the complete file path for the newly created DIAdem data. This allows you to
access the file later from DIAdem’s Load Data box, as discussed on page 8.

Quick Start Guide 5
Using DIAdem with ChartView
This method must be used for data acquisition
programs that have no integrated converter capable
of converting r aw binary data to the DIAdem data
format.
ChartView has no direct support for DIAdem. In this
case a stand-alone file converter is used to convert
binary data to the DIAdem format.
Note: The Data Conversion Utility (file converter)
is installed automatically when you install
ChartView from CD-ROM release version 1.9
or greater.
The following steps show how to convert a bina ry
file from a data acquisition program to DIAdem
format, then load the converted file into DIAdem.
A simplified view of the procedure is at right.
(A) Use ChartView to acquire and save data in
binary [raw binary] format.
(B) Use the Data Conversion Utility to convert the
raw binary format into the DIAdem format.
(C) Load the converted file into DIAdem.
ChartView, Data Conversion Utility, and DIAdem
on a Desktop Concurrently
During a session in which several acquisitions are to be followed by viewing each file in DIAdem, it is recommended
that: the data acquisition application, the file converter, and DIAdem remain on the desktop concurrently.
(A) Acquire and Save Data in Binary Format
1.
Open ChartView.
Consult the ChartScan Users Manual as needed.
2.
Select Binary Data Format.
This is done in ChartView’s Data Destination section (see figure).
3.
Acquire and Save Data.
In the example at the right we are saving a binary data file named
DATA_GG.IOT
to folder
E:XFER\BIN\
(B) Convert Binary Data to DIAdem Format
1.
Open the Data Conversion Utility.
Use a shortcut i con, or navigate from your desktop’s Start Menu as follows and
double-click on the Data Conversion Utility item:
Start ⇒ Programs ⇒ ChartView ⇒Applications ⇒ Data Conversion Utility
Select Binary Format

2.
Select "ChartView Binary" as the Data Type.
The first time you run the data converter, a dialog box prompts you to select a data
type. The data type designation is based on the program that was used to collect the
data, e.g., ChartView.
If the prompting dialog box does not appear, use the Select Source Data Type Tool
to select ChartView Binary (as shown in the figure at the right).
If this is the first time you are using the data converter you can skip
to step 4 since the DIAdem format is initially selected by default.
3.
Select the DIAdem File Format.
This can be done as follows by dropping down the
data conver t er's File menu and clicking
"Preferences." This opens a dialog box displaying
a list of formats into which your data can be
converted.
If there is not a check mark next to the DIAdem
item, click on it once to check it.
Note: You can select additional file formats for
other application uses; but for our Quick Start
Selecting the DIAdem File Format
purposes we only need to select the DIAdem
format.

4.
Click the Convert Button [on the data converter's tool bar].
A dialog box will appear that is similar to the Open File dialog used by many programs (see following figure).
Note that this directory differs for each of the View programs.
If this is the first time that you are converting files of this type, you will have to navigate to the directory containing
your data. For example, to get to

5.
Select the Files as you want to Convert.
In the example we only have one file available (
6.
Enter the Target Directory Path.
data_gg.iot
).
In the Target Directory textbox, type the path of the directory that you want to use as the parent directory of the
converted data. Note that you can press the Browse button to navigate to the target directory instead of typing it.
In the example above we used:
C:\WINDOWS\TEST_Save\
The converted data files will be placed in a sub-directory named "DIAdem". Thus the complete path for our saved
data is:
7.
Press the Convert Button (in the Select Files to Convert box).
C:\WINDOWS\TEST_Save\DIAdem\data_gg.DAT
This action starts the file conversion and displays a progress meter.
After the DIAdem format file has been created, we can load our acquired data into DIAdem as discussed in the
following section.
(C) Load the Converted File into DIAdem
(these steps are not exclusive to ChartView and can be applied to other acquisition programs)
If you do not already have DIAdem open, launch the program from a desktop shortcut (if applicable), or by
navigating from the PC desktop as follows:
Start ⇒ Programs ⇒ DIAdem ⇒ DIAdem
1. Click the DIAdem-DATA: Data Management button.
2. Click Load Data. A Load Data box appears.
3. Using the Load Data window, locate your DIAdem
target file and highlight its name.
In the example we have highl i ghted daqv.DAT.
Note: We reached this target file by navigating as shown in
steps A through E (below).
We used the Target Directory path we created earlier
C:\WINDOWS\TEST_Save\
The complete path for our saved data was
C:\WINDOWS\TEST_Save\DIAdem\data_gg.DAT
Note: DIAdem data files always have a "DAT" file
extension. The file name itself will match the name of
the raw binary file you converted.
If you need help finding a target directory path, see the
related tip on page 3; or consult your application’s
users manual, if needed.
