Global Virtual Channels

To open the DAQ Assistant to create global virtual channels, complete the following steps:

Note  If you are using LabWindows/CVI or Measurement Studio, you must create your global virtual channels in MAX.

1. In MAX, right-click Data Neighborhood and select Create New.

   If you are using a remote system running LabVIEW Real-Time, expand Remote Systems, find and expand your target, then right-click Data Neighborhood and select Create New.

2. In the Create New window, select NI-DAQmx Global Virtual Channel and click Next. The DAQ Assistant opens.

   You also can open the DAQ Assistant directly within LabVIEW, LabWindows/CVI, or Measurement Studio version 7.x or later:

   • In LabVIEW and LabVIEW Real-Time, use the DAQmx Global Channel control to open the DAQ Assistant. Right-click the control and select New Channel (DAQ Assistant).
   • If you are using LabVIEW 8.0 or later, you can create channels local to a LabVIEW Project, or you can create channels in MAX. To create channels in a Project, right-click My Computer in the Project Explorer window. Then, select New»Channel.
3. In LabVIEW 7.x, click the Configure pull-down menu and select Create DAQmx Channel (DAQ Assistant).
4. In LabWindows/CVI or Measurement Studio, first you must create a task as previously described. In the DAQ Assistant, click Add Existing DAQmx Global Channels to add global virtual channels to your task. You must use MAX to create global virtual channels.
5. Configure the global virtual channel.
6. Save your configuration.
   • If you opened the DAQ Assistant from LabVIEW or LabWindows/CVI, click OK.
   • If you opened the DAQ Assistant from Measurement Studio, select File»Save.
   • If you opened the DAQ Assistant from MAX, click Save Channel.

You now can use the global virtual channel in an application or add the global virtual channel to a task. Refer to the application software documentation for more information about using a global virtual channel or generating code.
