DAQLab is a new all-in-one data acquisition - control - SCADA - HMI - data analysis software package. DAQLab actually consists of two programs: DAQLab Acquire, which takes the data, stores it to disk, broadcasts it on a network, and automates your system, and DAQLab Control, which provides the complete user interface for setting your system parameters and creating your own screens. A single Control program can communicate with multiple copies of Acquire and multiple Control programs can communicate with a single Acquire. Acquire and Control can be run on the same computer, or on computers around the world. Because of this separation, acquisition rates can be guaranteed. Input and output channels are easy to configure. Acquisition rates are set on a channel by channel basis, so you do not need to log all channels at the same rate. The channel setup page displays a graph or table of the data and allows you to set outputs without creating any screens; this is useful for quickly testing your hardware. The channel view also has room for any notes you may want to keep about a channel. With DAQLab you can create an unlimited number of screens, and can even overlay them to keep important information on top. Data can be displayed as a text component or an animated image component that can be set up to perform specific actions when clicked. In addition to displaying data, text components can also be used for displaying things like Low / Medium / High, or just simple labels. DAQLab provides some powerful imaging capabilities and comes with a 3800 industrial image library. You can create schematics of your process, add buttons, switches, bar-charts, etc.. You can change images depending on your system's state and even animate images. You can also place graphs on any of your screens. These graphs can display Y vs Time trends, or X vs Y comparisons. You can create as many traces as you may need on up to 12 different Y axes. Traces use expressions, so there's no need to pre-calculate the values you would like to graph. For example, if you want to plot Sin(PumpRotation^2)/PumpSpeed vs. Log(TankPressure) you simply enter these two expressions in the trace setup. Graphs offer many features for displaying your data including error bars, axis, line and bound annotations. Graph markers can be used to identify points and quickly analyse peaks in your data. DAQLab creates the graphs in a background process, so even the most complicated graphs won't make DAQLab sluggish. Your process or experiment can be automated through the use of sequences. Sequences can be as simple as setting some initial outputs to full-blown soft-PLC system. Sequences have some of the attributes of a programming language, but are much easier to use. You can have as many Sequences as you deem necessary. Multiple Sequences can be run concurrently, either triggered manually, or started by another Sequence. This makes it very easy to separate out different tasks. Unlike most automation software, DAQLab's Sequences are completely time driven. This means that every Sequence command has a time associated with it that determines when the command will execute. Of course time is all relative and you can branch to different locations or times in a sequence, even to times that don't have a command associated with it. DAQLab provides a significant amount of data processing and analysis tools to complete your data acquisition tasks and convert your data into something useful. Since DAQLab integrates the data analysis with the data acquisition and data display, you can perform your data analysis on your data as you are taking it. You can also directly load your data from previous experiments run with DAQLab and analyse it using the same tools you would on your live data. You can even do this while DAQLab is busy taking new data. DAQLab allows all the standard mathematical processing you may need, including curve fitting, interpolation, statistical functions, smoothing, FFT, correlation, convolution, histograms, and percentile graphs. In addition to this, DAQLab offers a few unusual functions that you'll find really helpful for dealing with time. These include an Align function to align data points taken on different time scales, a ShiftTime function for adjusting data with different retension times, and an InsertTime function for quickly generating constant functions vs. time. With the exception of curve fitting and percentile graphs, all the functions in DAQLab can be used on your live data in real time. This means you get your results immediately! Because there is never a lab notebook around when you need one, DAQLab provides a notebook for you. By using the Quick Note feature, you can enter a time stamped note that is automatically stored to disk. If you need to get data from another program, you can import data from a delimited text file: If you need to get your data into some other program you can either process the data directly from storage, or export it from DAQLab Control in a delimited text form DAQLab has drivers for many well know hardware manufactures such as National Instruments, ComputerBoards, IOTech, ACCES IO in addition to Audon's LabJack USB unit and the Smart A/D range. More are being added all the time. There is also a generic serial device driver and DAQLab supports OPC so it can communicate with a whole host of industrial equipment such as PLC's, remote terminal units and process controllers. Pricing is very competitive with four DAQLab versions for every budget. The feature-limited "Lite" version is only £49 while the full version is only £459. __________________________________________________ April 2002
