New Script module means more flexibility for DASYLab users

Want to know which new feature stands out in the latest version 13 release of DASYLab – the easy-to-use software for configuring and controlling custom DAQ and analysis applications? If she had to choose from the extensive enhancements, CJ Butler, DASYLab Product Marketing Manager at Measurement Computing, believes the new Script module is the most important, most useful new addition to DASYLab’s toolset.

She said, “The script module addresses a number of instances where DASYLab functions don’t quite do what’s required or a new driver, computation or file type is needed. For example, several years ago, one of our customers needed a very specific, very proprietary computation and so they hired a C programmer to create a module for them using the Extension toolkit. Now with the introduction of the new Script module, it’s very likely they would have been able to use the Python script language to create the module themselves. It would have been faster, cheaper and could have been done in-house. These guys already use Python in a number of other areas. This customer is now looking at the Script module and Python to customise a PID function.”

She goes on to say, “What kinds of things will you be able to do with Python? I wrote a driver as part of the learning and testing process. I had a serial port device that was too complex for the RS232 module, and provided ActiveX/Com objects for developers. It was pretty easy to set up a module that found and initialised the device, programmed it, and then acquired all available data from it at 20-30 samples per second. MeasX has done a number of drivers using the Script functions and the DASYLab IVI modules are all created using the Script functions.”

CJ then tells us about an ongoing project. She explains, “I’ve been working on two Script modules. The first is a supplement for customers with worksheets that use the DDE Out module to send data to Microsoft Excel. It looks for and opens the target Excel workbook before the measurement starts, so that it is ready for the DDE Out. The second takes the thought a step further. Using the Example from the Help, I added the workbook logic that I’d done for the first, and created a Script that would open or create an Excel workbook, create a new sheet and then log data to it.”

The new Script module looks set to open up DASYLab usage for both end users and resellers by enabling them to enhance and extend DASYLab beyond the out-of-the-box release. The ability to export and package it as a standard module secures their intellectual property and allows them to sell or share it without the code. The possibilities are immense, and DASYLab’s developers are really hoping users will take advantage of this new feature!

DASYLab customers who want to share (or sell) their new scripts or modules on the DASYLAB website should email

Disclaimer – the Script module cannot do everything. If you need a new Display module, for example, you will still need to use the Extension Toolkit.

Custom point-and-click modules make no-programming DAQ software even more flexible

dasyvistaNew DASYLab 13 lets users create their own custom functions to add to DASYLab’s drag-and-drop module library

A new version of DASYLab, the point-and-click data acquisition and control software from measX GmbH & Co (Mönchengladbach, Germany) is now available in the UK from Adept Scientific (Letchworth, Herts). DASYLab’s function block interface makes it easy to set up and control measurement data applications in a standard PC Windows environment without programming; and new DASYLab 13 sees a significant upgrade in capability and flexibility by allowing users to define their own custom functions to add to DASYLab’s extensive library of drag-and-drop modules.

With this new version, DASYLab becomes almost infinitely expandable. It’s simple to create your own individually defined, custom function module using the open-source Python™ scripting environment (version 2.65). Using this new Scripting module, it’s easy to write a custom computation, create a driver to communicate with hardware and software, or configure module and channel parameters. For example, you could create a custom temperature scaling module that takes one temperature input and outputs the temperature data in three different units.

Setting up and controlling a data acquisition application with DASYLab eliminates hours of coding. DASYLab is designed for those who want to get down to work straight away, without having to write programs. Its simple, point-and-click interface lets you set up powerful, sophisticated data acquisition routines quickly and easily. With DASYLab you can create your own individual measurement or analysis application in a few minutes. From research and analysis to large-scale production and quality control, DASYLab is the software of choice for creating flexible and powerful monitoring and control applications, fast.

The new Scripting module is one of several new modules, additional options for existing modules and other enhancements in DASYLab 13. For example:

  • A new Resample module lets you transform data from a time axis on an angle axis in order to analyse measurement data from rotating systems; this module converts vibrations on a concentric axis to the rotation angle.
  • A welcome output addition to the Write Data module is to .csv (comma-separated values) text file, using the new ASCII (CSV Preset) file format available in the module.
  • The new IVI Scope Module lets you continuously display data from external devices which support the IVI Scope instrument class. IVI modules now also display error codes and descriptions generated by the hardware driver.
  • The new NI-XNET driver module lets you acquire and output data with National Instruments NI-XNET hardware, which supports the controller area network (CAN) and local interconnect network (LIN) bus systems.
  • A number of new options have been added to various existing modules, for example a real timestamp is now available in the Average module and there’s a new re-trigger option to the Combi Trigger module.

Compatible with data acquisition hardware from most manufacturers, DASYLab lets you focus on your particular area of expertise, while tapping into the power of the display, analysis and control features needed to fully process measurement data. Its flexible configuration of user interface and displays, interactive tutorial and more than 150 examples help you quickly set up and develop your application. This latest version combines powerful functionality, flexibility and ease of use for PC measurement and control.
