Calls a VI sourced in the version of LabVIEW you specify and returns the output of the VI. Configure the settings for this node to call the desired VI. This node requires you to have LabVIEW 8.0 or later ...

Executes its subdiagram n times. The iteration terminal provides the current loop iteration count, which ranges from 0 to n-1. This product does not support FPGA devices Not supported in VIs that run in ...

Repeats the code on its subdiagram until a specific condition occurs. A While Loop always executes at least one time. A While Loop behaves similarly to a do while loop in other programming languages. This ...

Before you begin to compile FPGA code into a bitfile, configure LabVIEW to use the FPGA Compile Cloud Service (recommended) or an FPGA compile farm. Complete the following steps to compile your FPGA code ...

You can store and transfer data on an FPGA using FIFOs, memory items, FPGA registers, or handshake items. Use the following table to determine the best type of data storage and transfer for your application. ...

When you compile code in an Optimized FPGA VI, the compiler performs optimizations. Knowing what patterns the compiler looks for in order to apply optimizations can help you understand performance you ...

Use Transmission Control Protocol (TCP) to reliably transfer data between a client and a server. To transmit data using TCP, you must develop the code to send and receive data on both the client and the ...

Use the User Datagram Protocol (UDP) to transfer data to a single client, known as unicast communication, or between a number of processes or processors that have opted into a group or receivers, known ...

Placeholders represent nodes on the diagram that existed in the original version of LabVIEW but do not exist in your current version of LabVIEW NXG. Fix placeholders in your converted code to replicate ...

Returns or creates a reference to a notifier. Use the reference this node creates when calling other Notifier nodes. This product does not support FPGA devices Not supported in VIs that run in a web application ...

Real-Time Nodes (G Dataflow) Real-Time Watchdog Timer Nodes Configure, restart, or clear a watchdog timer. RT Debug String Sends a string to an output port for display, or writes a string to the system ...

Returns the number of elements in each dimension of an array. This product does not support FPGA devices Not supported in VIs that run in a web application Diagram Panel Indicator Comments size(s) for ...

Returns a portion of an array starting at a specified index and containing a specified number of elements. This product does not support FPGA devices Not supported in VIs that run in a web application ...

Converts an array of any dimension to a delimited string that mimics a spreadsheet with rows, columns, and pages. This product does not support FPGA devices Not supported in VIs that run in a web application ...

Concatenates multiple arrays or appends elements to an n-dimensional array. This node constructs the new array differently depending on the dimensionality of the inputs and whether the Concatenate Inputs ...

Contains one or more subdiagrams, or cases, exactly one of which executes when the structure executes. The value wired to the selector terminal determines which case to execute. Case Structures behave ...

Closes a reference to an open file to free the resources used by the reference. Error I/O operates uniquely in this node, which closes the file regardless of whether an error occurred in a preceding operation. ...

Allows you to read and write the elements of a cluster. This product does not support FPGA devices Not supported in VIs that run in a web application Configuring the Node to Read or Write To change whether ...

Creates the reader endpoint of a network stream. This product does not support FPGA devices Not supported in VIs that run in a web application timeout in ms Time, in milliseconds, that this endpoint waits ...

Creates the writer endpoint of a network stream. This product does not support FPGA devices Not supported in VIs that run in a web application timeout in ms Time, in milliseconds, that this endpoint waits ...

Creates a software-triggered timing source you can use to control the execution of a timed structure. The timing source waits until the first timed structure that uses the timing source starts. This product ...

Returns a reference to a user event with the name and data type you specify. This product does not support FPGA devices Not supported in VIs that run in a web application Executing Code Based on a User ...

Subtracts 1 from the input value. This product does not support FPGA devices Supported in VIs that run in a web application Behavior for Enum Data All arithmetic functions except Increment and Decrement ...

Removes access to the data that the data value reference or the external data value reference points to. This node deletes the reference but leaves the data intact. Memory leakage might occur if you do ...

The Multirate Diagram node allows you to integrate a Multirate diagram into a VI targeted to an FPGA. The Multirate Diagram node behaves differently in a VI targeted to an FPGA than in a VI targeted to ...

Removes an element from the front of a queue and returns the element. If the queue becomes invalid because the queue reference is released, then this node stops waiting and returns an error. This product ...

Contains one or more subdiagrams, or cases, of which only the enabled subdiagram executes. Use the Disable Structure to disable a section of the diagram. This product does not support FPGA devices Supported ...

Adds an element to the front of a queue. Queues typically use a first-in-first-out flow where data is enqueued at the back of the queue and dequeued in the front of the queue. In rare situations, you might ...

Waits until an event occurs, then executes the appropriate case to handle that event. The Event Structure has one or more subdiagrams, or event cases. Only one event case executes when the structure executes ...

Transfers all data to the reader endpoint before data flow resumes. You can call this node from the writer endpoint only. This product does not support FPGA devices Not supported in VIs that run in a web ...
