Use the pop up dialog box to display an error if any.įigure 1: DAQmx Base Thermocouple Example.Clear the Task using DAQmxBase Clear Task.vi.Stop the task using DAQmxBase Stop Task.vi.Continue reading data until the stop button is pressed or an error occurs. By default, the Read VI reads all available samples, but you can specify how many samples to read at a time and the timeout value. Read N samples using DAQmxBase Read.vi and Plot it.Start the acquisition using DAQmxBase Start Task.vi.Specify the hardware timing parameters using DAQmxBase Timing.vi.Create a Thermocouple (TC) temperature measurement channel using DAQmxBase Create Virtual Channel.vi.Create empty task using DAQmxBase Create Task.vi.The steps to do this are listed below with the resulting block diagram in figure 1: The first method, which is preferred, involves dynamically creating the task using DAQmx Base Create Task VI followed by the DAQmx Base Create Virtual Channel VI. There are three ways to configure tasks in NI-DAQmx Base.
