Measurement data acquisition
Create and automate measurement sequences without programming
DASYLab 2022 is a versatile application system for all tasks in measurement, control, regulation and automation.
DASYLab 2022 Description
Equipped with a wide range of software and hardware interfaces you only need DASYLab to reliably record, analyze, visualize and further process signals of all types.
DASYLab stands out due to its strikingly simple method of use: measurement engineering applications are intuitively and interactively designed and displayed graphically in the form of a dataflow diagram without any programming at all.
The function modules required for a specific task are placed in the circuit diagram, linked to other modules and adapted to the current task using structured configuration dialogues.
Boundles flexibility due to more than 120 default modules for creating your specific application.
A wide spectrum of analysis, control and visualization modules are available for creating the application, these range from measurement engineering single functions up to preconfigured standard sequences. These include analog and digital inputs and outputs, triggers, mathematics, statistics, digital filters, FFT analyzes, buttons, switches and much more.
Use just one single module to create a datalogger
On top of this, you can comfortably develop and incorporate your own extensions using the integrated Python interface. Everything is possible.
DASYLab is available in four extension levels, so that both beginners and experienced users can implement measurement and test sequences to meet their requirements.
Use two modules to create a multichannel writer.
Use three modules to create an oscilloscope with FFT signal evaluation.
Four modules are required for a measurement sequence, which fulfills the basic requirements on almost any measuring task.
Five modules are required for data acquisition with FFT signal evaluation, statistics function and results presentation.
Its simplicity and its wide applicability make DASYLab since 1993 one of the leading applications in education, research and engineering for industry, production and quality management.
With DASYLab you are not only capable of capturing and visualization of measured data …
Your PC interface is turned into the measuring instrument interface each time, and it can be individually configured and designed. DASYLab supports data acquisition hardware from numerous manufacturers and offers a wide range of established software interfaces and protocols. External measuring devices are contacted and configured in a simple manner directly via function modules. Up to 512 channels per measured value acquisition are possible depending on the hardware used.
DASYLab can read or write data which has either been processed by the measX X-frame application or by the National Instruments DIAdem.
… you are also up to a powerful online signal analysis!
DASYLab offers a wide range of functional modules for signal processing, mathematics and statistics in order to work out the properties of the recorded signals simply yet precisely.
SEven specific modules for third and octave analysis and for convoluting and weighting signals are offered by DASYLab.
- analog and digital inputs and outputs, counter input and frequency output
- CAN bus and LIN bus
- ModBus / RTU
Automating measuring sequences without programming
Automation tasks are solved graphically with DASYLab without programming. To do this, the software provides a range of function modules such as signal generators, switches, controllers and function generators. The corresponding modules are placed and configured in the circuit diagram so that logic switches, controls and analyzes can be implemented.
DASYLab can read or write data for further analysis which can either been processed by the measX X-frame application or by the National Instruments DIAdem.
Sequence Generator as highlight
A configurable sequence generator is provided for precise time-dependent controls with complex control signals. It creates the sequence profile using simple parameterization of the individual program stages, which, for example, you use for controlling your test bench. This means that switching processes are implemented synchronously with this control profile.
State machine as highlight
Complex test sequences, which can be set up using a combination of action modules, trigger modules, relays and links as an alternative can be compiled to form fewer modules using the state machine module. These sequences are particularly simple to create and maintain since stages within the module can be added, deleted or changed in their sequence as required. When setting up a step sequence conventionally in DASYLab, all the modules are always processed simultaneously in parallel – especially the parts of the step sequence which are not actually needed at that moment. In comparison, only the active parts of the step sequence are processed in the state machine module since all decisions about the work stage are made using one single module. This results in a considerable decrease in computing time and memory requirement.
Acoustics measurement with SLM Add-On
The sound level meter module has the following features:
- Time weighting: Slow, Fast, Impulse, Leq following DIN IEC 651 and DIN IEC 804.
- Easy microphone calibration with a pistonphone; In calibration mode, DasyLAB 6 detects the channel / microphone to calibrate and calculates the correct values.
- The correction values are stored with the worksheet.
- The module has 16 inputs and 16 outputs for the weighted and dB scaled sound levels.
- We recommend a 16 bit AD converter with microphone power supply.
Sound Power Measurement Module
The sound power measurement module can calculate the sound power for a maximum of 16 input channels (from the sound level measurement module) 1 output channel, switchable to:
- Measurement surface sound power.
- Sound power level (SPL) of all active channels.
The module properties allow you to set the four corrective values in dB or use the “wizards” to determine them:
K0: Correction value for air pressure and temperature. Direct input of the dB value or pressure and temperature. (Only necessary for class 1 measurements according to DIN 45 635.)
K1: Correction value for extraneous noise correction (background noise, signal-to-noise ratio). Direct input of the dB value or taken from last measurement. K2: Correction value for environment feedback (reflections). Direct input of the dB value or input of the room’s metrics:
– reverberation time …
Ls: Correction value for the enveloping surface. Direct input of the dB value or input of the surface metrics (guided with graphics). Like DIN (2a, 2c, b)
– Spherical, hemisphere, quarter globe
– Cuboids (detached, at a wall, at a wall and ceiling)
The module works according to the following standards: DIN 45 635, DIN EN 23 741, ISO 3741, DIN EN 23 742, ISO 3742, DIN EN 23 744, EN ISO 3744, DIN EN 21 680, ISO 6395
Creating your own DASYLab modules
Right from the start DASYLab provides a wide range of modules for different measurement, control and analysis tasks. If functionalities, hardware or software components over and above this are necessary for an application, these can be integrated by any (program-experienced) user at reasonable expense using the integrated Python interface.
These could be additional input modules or modules for data output, and also special mathematical functions which are not included even in DASYLab despite its wide range of function modules.
Basic settings, for example the number of inputs or outputs and the data flow properties, which are accepted by the module, can be conveniently specified in a presetting wizard. Only the script code needs to be entered in the dialogues for each individual interface in order to specify the functionality of a new module. Module parameters which are to be freely configurable later on are selected from a stock of stipulated dialog elements, and then made editable and compiled to form a simple configuration dialog using a script.
Python script modules can be implemented and managed in all DASYLab versions. Users of the Full and Pro version can also create, process and export Python script modules.
Look and feel to your own specifications
DASYLab offers users a wide range of facilities for designing the working environment to meet their own personal requirements. This applies both to the user interfaces (the so-called layouts) and user guidance through individual applications, and also to the reports and protocols which can be generated.
A wide range of control and display modules are available for interface design: these range from standard functions such as the magnified display of graphical signal sequences up to color-coding of numerical display on limit value infringements. You can quickly and simply configure all operating elements and display windows to meet your own requirements by specifically placing the visualization and control modules and providing them with texts and graphics.
Up to 200 different layout pages can be defined with the aid of the integrated layout tool.
You can display your measured data as curves using the writer, Y / t chart and X / Y chart modules. The table and digital instrument function blocks display the recorded measured data numerically. Freely scalable analog instruments, bar and state displays are especially suitable for the presentation of process and test controls.
Reports and documentation
DASYLab can also support you in professional results presentation. The design of log sheets and reports can be flexibly drawn up and configured.
