DAQmx Physical Channel Constant
Lists all physical channels on devices installed in the system. Select Browse to select multiple physical channels. Right-click the constant, and select I/O Name Filtering from the shortcut menu to limit the physical channels that the constant displays and to limit what you can enter in the constant.
If you right-click this constant and create a Property Node, the Property Node is for the constant itself and does not provide any configuration options for physical channels.
