Creates an RT FIFO or obtains a reference to an existing RT FIFO that you can use with other RT FIFO nodes.
The number of elements in the array for each RT FIFO element. This input only applies if the RT FIFO elements are arrays. RT FIFOs do not support multi-dimensional arrays.
The number of elements in the RT FIFO.
The name of the RT FIFO that you want to obtain or create.
Default: Empty string
Defines the type of data that you want the RT FIFO to contain. RT FIFOs do not support data types of variable size, such as clusters, strings, and variants. RT FIFOs also do not support multi-dimensional arrays.
Waveform Data Transfer with RT FIFOs
If you use an RT FIFO to transfer waveform data, the attributes of the waveform do not transfer. The attributes element of a waveform is a variant, which is variable-sized and therefore incompatible with the RT FIFO.
A Boolean that determines whether to create a new RT FIFO if the FIFO specified by name does not currently exist.
|True||The node creates a new RT FIFO if the FIFO specified by name does not exist.|
|False||The node does not create a new RT FIFO and returns an error if the FIFO specified by name does not exist.|
Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.
Default: No error
The number of datapoints for every element of the array of waveforms. This input only applies if the RT FIFO elements are waveforms.
Read and write modes for a new RT FIFO. The read and write modes define the behavior of an RT FIFO that reads a value from an empty RT FIFO or writes a value to an RT FIFO that does not have an empty slot. You can specify one of the following modes for reads and writes:
If you use RT FIFO Create to return a reference to an existing RT FIFO, the reference uses the read and write modes of the existing RT FIFO and ignores the modes specified with r/w modes.
Read mode for the RT FIFO.
Write mode for the RT FIFO.
References an existing or newly created RT FIFO.
Error information. The node produces this output according to standard error behavior.
