NI-DAQ Simulated Devices
How to configure the system to
build the DAQ applications without
hardware installed.
How to create simulated devices
To create an NI-DAQmx simulated device, NI-DAQmx 7.4 or later must be
installed.
Open Measurement & Automation Explorer (MAX). Right-click My System >>Devices and
Interfaces and select Create New... In the subsequent dialog, select NI-DAQmx
Device>>NI-DAQmx Simulated Device. The Choose Device window prompts you to select
a device.
How to create simulated devices
Select the device you want to create as an NI-DAQmx simulated device. Click
OK in the Choose Device window to close the window. The NI-DAQmx simulated
device appears in MAX. The icon color of the NI-DAQmx simulated devices
differs from real devices. Real devices are green, and simulated devices are
yellow.
Configure the BNC-2120
The BNC-2120 input pannel is used to connect the signals to the PCI-6221 DAQ
device.
From the pop-up menu
select Properties.
Check if the BNC-2120 is present and active in
the Accessory tab.
Create the NI-DAQmx Tasks
You can create now the NI-DAQmx Tasks in the same way like during the laboratory
exercise (Sensor interfaces). See the laboratory suplementary instruction (the
presentation).
Simulated tasks
Create the NI-DAQmx Tasks
Click Test in the toolbar at the top of the page. Both NI-DAQmx simulated
devices and real devices have test panels in the DAQ Assistant. Notice the noisy
sine wave being returned as simulated data on the channels of the DAQ task.
Build Application
Now you can use simulated tasks in your LabVIEW application.
