Palette Object Description
DAQmx Device Name

Lists all devices installed in the system. Right-click the constant, and select I/O Name Filtering from the shortcut menu to limit the devices 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 is not a DAQmx Device Property Node.

DAQmx Set Power Up States

Updates the states to which to set physical channels on a device when the device powers up or when you reset the device. A device stores power up states in non-volatile memory that you can write to only a limited number of times. Therefore, you should use this VI as infrequently as possible. This VI writes to the non-volatile memory only if a setting you request is different from the one currently stored. This VI writes power up states in the sequential order of the power up states array. Therefore, any physical channels with multiple entries in that array use the highest array index.

DAQmx Get Power Up States

Returns the power up states that physical channels on a device are set to when the device powers up or when you reset the device. This VI returns data for only one line.

DAQmx Device Property Node

A Property Node with the DAQmx Device class preselected. Right-click the Property Node and choose Select Filter from the shortcut menu to make the Property Node show only the properties supported by a particular device installed in the system or supported by all the devices installed in the system.

DAQmx System Property Node

A Property Node with the DAQmx System class preselected. Right-click the Property Node and choose Select Filter from the shortcut menu to make the Property Node show only the properties supported by a particular device installed in the system or supported by all the devices installed in the system.

DAQmx Add Network Device

Adds a Network cDAQ device to the system and, if specified, attempts to reserve it.

DAQmx Reserve Network Device

Reserves the Network DAQ device for the current host. Reservation is required to run NI-DAQmx tasks, and the device must be added in MAX before it can be reserved.

DAQmx Unreserve Network Device

Unreserves or releases a Network DAQ device previously reserved by the host.

DAQmx Delete Network Device

Deletes a Network DAQ device previously added to the host. If the device is reserved, it is unreserved before it is removed.



Subpalette Description
