The LabVIEW Data Acquisition VIs are located on the Data Acquisition palette and the DAQmx - Data Acqusition palette. The Data Acquisition palette contains the traditional NI-DAQ VIs. The DAQmx - Data Acquisition palette contains the VIs for NI-DAQmx. The DAQmx - Data Acquisition palette contains all of the VIs necessary to perform analog I/O, digital I/O, and counter/timer operations. The VIs are organized so that the most common operations can be performed using the VIs. You can configure a task to perform a very specific function by using the Property Nodes in the palette. Many applications that do not require advanced timing and synchronization can be performed by using the DAQ Assistant Express VI. This course describes the use of the DAQ Assistant Express VI to perform data acquisition. For more information on using all the features of NI-DAQmx, refer to the NI-DAQmx Help or attend the LabVIEW Data Acquisition and Signal Conditioning course. The DAQ Assistant Express VI allows you to easily configure the data acquisition device. When you place the DAQ Assistant Express VI on the block diagram, a dialog box appears where you configure a local task to perform a specific measurement function. Creating a local task allows you to specify the exact type of measurement to take.

After you create a task, the information for the local task is stored in the DAQ Assistant Express VI. You can reconfigure the DAQ Assistant Express VI by double-clicking the VI and creating a new task.
