DASYLab is a data acquisition and evaluation system using a visual programming language for Windows from National Instruments. The acronym stands for "Data Acquisition System Laboratory". The first version appeared in 1993 and was developed by the former DATALOG GmbH, the further development was taken over by National Instruments[1] in 1998. The main field of application is the acquisition and visualization of measured values via various data acquisition hardware of different manufacturers. Several types of interfaces such as analog and digital I/O’s, Counter and frequency outputs, CAN-Bus, LIN-Bus, RS-232, IEEE-488, ModBus/RTU, OPC-DA, PLC, or ODBC are supported.
The program is also used in training in technical professions and universities to teach knowledge of signal analysis. In this context, a standard work is the book "Signals, Processes and Systems[2]" by Ulrich Karrenberg, published by Springer, Heidelberg/Berlin 2013.
Functions
The programming of a measurement, processing and evaluation chain is done graphically by placing individual modules on the screen – in the so-called circuit diagram. Modules have a defined function (e.g. arithmetic) and can be parameterized after creation (e.g. add, subtract data etc.). The data flow is realized by connections between the inputs and outputs of the modules. The modules are divided into groups for data acquisition, processing and visualization or data storage.
Another option of the program is the possibility to design user-specific layouts, which are used e.g. as user interface for users or for special visualizations. From version 13 on, a script module allows the insertion of user-defined functions. The script language used is Python[3].
Variants
DASYLab is delivered in different versions (Pro, Full, Basic and Lite), which differ in their range of functions. In addition, there is a free runtime version, which only allows the execution of existing schematic files (.dsb), but not their editing.
