Solve acquisition problems
in just a few minutes
The easy-to-use DASYLab software
helps you solve complex data
acquisition and control scenarios
easily and quickly by working with a
flowchart directly on the screen.
Module icons are placed on the
screen and connected with wires in
a schematic diagram, which
represents the flow of data through
the system. Each icon represents an
input, operation or output function.
Real-time acquisition rates of up to
800KHz and on-line display of up to
300KHz can be achieved. The
actual rates depend on the data
acquisition board and other
hardware used.
Acquisition, control, and
analysis modules
The versatility of DASYLab lies in its
rich set of function modules. These
include analog input (ADC), analog
output (DAC), triggers, digital I/Os,
function generators, action
operation*, digital filters*,
spectral/FFT analysis*, and
mathematical, statistical and logical
operations. Output modules allow
for file writing, DDE output, and
various types of displays, including
strip charts, x-y graphs, digital and
analog meters, and bar graphs.
User definable icons include the
ability to create a Black Box icon
containing many icons, enhancing
the usability for large worksheets.
The module icons can be connected
manually or, using the integrated
Autorouter feature, wire paths will
be determined automatically.
The Display
Results of acquisition and analysis
can be displayed in strip charts,
t-y graphs, and x-y graphs with a
selectable system of coordinates.
Linear, logarithmic, and polar
coordinates are available. The
results can also be displayed as bar
graphs, analog and digital meters,
and status lamps. The operator can
interact with the displays while the
system is running, changing the X,
Y or time scales, selecting data
channels to be displayed, or even
looking back in time on the chart
recorder. With DASYLab Plus, those
changes to the displays can be
done automatically based on system
events.
Signal Generation
You can test your DASYLab
flowcharts by using simulated
signals from the signal generator by
temporarily replacing the ADC icon
with the signal generator. This, in
combination with the mathematical
functions, can be used to generate
complex wave forms. In addition, a
sequence generator is available that
allows you to generate even more
arbitrary functions, combining ramps
and curves.
Control PID control, and binary logic control
can be defined using the module
icons. Pulse generators can be used
for exact time dependent control,
even with complex control signals.
Events and actions*
There are a class of modules that
allow you to cause events in the
system based on user action
acquired or calculated data. These
events can automatically cause
certain action. Using the action
modules, you can print a display
window, change the characteristics
of a display window, or even change
the whole display. You can
automatically notify the operator of
problems and suggest remedies.
Saving and loading data
Data can be saved to disk in several
formats via the file I/O icon.
Importing of data from disk during a
real-time run is also supported from
files of several formats. Store and
retrieve data from standard ODBC
databases. Using the DDE
(Dynamic Data Exchange) interface,
DASYLab can act as a server,
transferring data on-line to other DDE compatible
Windows programs.
Controlling Your Test Sequence*
The Worksheet Test Manager allows
you to control the sequence of tests,
the order in which they are performed,
and provides a high level view of the
series of tests.
Analysis Toolkit Option*
Add a variety of high-end
functions,including the Transfer
Function, Octave analysis, Rainflow
Statistical Analysis,and
Setpoint/Sequence Generation.
DDE IMPORT
Other programs such as Visual
BASIC can control the DASYLab
application by starting, pausing, and
stopping the experiment.
RS-232/RS-485/OPC
Read data from a wide variety of
instruments including scales,
balances and data recorders.
