- Place a DAQmx global channel control on the front panel.
- Right-click the control and select Create DAQmx Channel»In MAX or Create DAQmx Channel»In Project from the shortcut menu. If the VI is not in a project, the In Project option is grayed out.
- Follow the onscreen instructions to configure the global channel.
- When you save the task and exit the DAQ Assistant, LabVIEW sets the DAQmx global channel control to the name of the channel.
Refer to Taking a Measurement with NI-DAQmx in LabVIEW for a walkthrough of the DAQ Assistant.
After you create a global channel, you can use the DAQmx global channel control to generate code for that global channel.
You also can use MAX to launch the DAQ Assistant and create a channel.
