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

B-13

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.

B

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.
