Editing a Task or Global Virtual Channel

NI DAQ Assistant

Editing a Task or Global Virtual Channel

You can use tasks and global virtual channels in your NI application software or in MAX.

LabVIEW

Complete the following steps to edit a task or global virtual channel saved in MAX:

  1. Place either a DAQmx Task Name control or a DAQmx Global Channel control on the front panel.
  2. Select the task or global virtual channel from the pull-down list.
  3. Right-click the control and select Edit DAQmx Task or Edit DAQmx Channel. Then, select the destination.
  4. Modify the task or global virtual channel when the DAQ Assistant launches.
  5. Click OK to save the changes.

LabVIEW SignalExpress

With LabVIEW SignalExpress 2.5 and later, you can import tasks from MAX and copy global virtual channels from MAX into DAQ steps. If you import a task from MAX, the task becomes local to that LabVIEW SignalExpress project, and you cannot save it back to MAX. Also, any global virtual channels contained in the task become local virtual channels. Then, you can use the channels in your LabVIEW SignalExpress application.

LabWindows/CVI

You must use MAX to edit global virtual channels.

To edit a task, select Tools»Create/Edit DAQmx Tasks and choose the task you want to edit. You also can edit MAX-based tasks within MAX by selecting Data Neighborhood»NI-DAQmx Tasks and choosing the task you want to edit.

Measurement Studio

You must use MAX to edit global virtual channels or MAX-based tasks.

To edit a project-based task, go to the project and double-click the .mxb file to launch the DAQ Assistant.

  3. Click the task or global virtual channel you want to edit.
