Data acquisition software phones home!

DASYLab data acquisition software now not only lets users monitor events on screen, it also signals alerts to pre-defined events remotely, via networks, the Web, email or SMS- enabled mobile phones.

The latest version of DASYLab data acquisition software not only lets users monitor test stands, development rigs and processes on screen, it also signals alerts to pre-defined events remotely, via networks, the Web, email or SMS- enabled mobile phones.

With its intuitive point-and-click interface, DASYLab makes it easy to set up, visualise and document data acquisition applications without programming or command-line instructions.

DASYLab - point-and-click software for applications that link sensors and instrumentation to a PC - is flexible enough to cope with complex data acquisition set-ups and ongoing reconfigurations.

Yet it requires no programming skills: setting up on-screen displays and controls, triggering and signal processing is simply a matter of dragging icons into place and connecting them with a mouse click.

The latest version of the software, DASYLab 5.5, adds a number of new features and functions that extend DASYLab's ability to manage data acquisition scenarios.

Much enhanced remote communication capabilities mean that DASYLab 5.5 can, on a pre-defined event, be set up to initiate emails or even SMS (Short Message Service) messages to mobile phones.

Messages can incorporate relevant data from the system, opening up the possibility of remote monitoring.

The trigger event can be an alarm setting, which automatically alerts a supervisor.

DASYLab 5.5 implements DataSocket technology, which allows information to be exchanged very easily with other applications, over networks, intranets or the internet.

DASYLab's DataSocket Import and Export Modules communicate with any device or data source using the OPC (OLE for Process Control) server protocol, an increasingly common standard for measurement and automation devices, fieldbus instrumentation, data acquisition systems and distributed systems.

This technology is based on Microsoft's ActiveX controls, which can also be embedded in a web page so that DASYLab data can be viewed remotely through a web browser.

Other new features in DASYLab 5.5 include a cycle buffer module to store large quantities of data either side of a trigger event; pulse-width- modulated (PWM) analysis to measure values from PWM waveforms; an open database connectivity (ODBC) module for creating database links; event-driven auto-zero; and more.

Designed for industrial research and scientific laboratories, DASYLab is probably the world's easiest-to-use data acquisition package.

Though its simplicity makes DASYLab ideal for those with no PC programming experience, users who do have programming skills will benefit from the speed with which systems can be set up and subsequently developed.

It supports a wide range of data acquisition hardware from all leading manufacturers.

DASYLab includes a wide range of function blocks - analogue outputs and inputs, digital I/Os, user-definable triggers, function generators, filters, signal adaption, virtual instruments and analysers, and mathematical, statistical and logical operations - as well as output modules to record events to file and a standard DDE output to communicate with other programs.

Function blocks can be combined in almost unlimited ways, within worksheets of any size, to allow real- time data analysis of even the most complex systems.

Users can zoom in on a specific event or data point, scroll back to study historical trends and monitor events as they happen.

For users needing even more functionality, an extended edition of DASYLab is available.

The additional modules include FFT/spectral analysis; data windowing; digital filter; regression; correlation; data backup; and an event-driven action module.
