What Is Data Flow?

Each block diagram node executes only when it receives all inputs

Each node produces output data after execution

Data flows along a path defined by wires

The movement of data determines execution order

Formula: Result = (A+B*C) / (D-E)

28 ni.com

What Is Data Flow?

Each block diagram node executes only when it receives all inputs

Each node produces output data after execution

Data flows along a path defined by wires

The movement of data determines execution order

The [Multiply] and [Subtract] operations can execute at the same time

since they dont have any data dependencies.

29 ni.com

Dataflow Languages Naturally Express Parallelism

Data Parallelism

Task Parallelism

The LabVIEW compiler will automatically multithread code expressed in parallel

30 ni.com

Text Loops and Their LabVIEW Equivalents

int x = 0;

String y;

while (x < 5)

{

y = functionCall(x);

printf(y);

x++;

}

for (i = 0; i < 10; i++)

{

/* loop body */

}

for (i = 0; i < 10; i++)

{

if(check(i)) break;

}

Event and Case Structures

Event Selector Label This indicates which subdiagram is visible

and details the event that the code within the

diagram handles.

Selector Terminal The value wired to this terminal determines

which of the subdiagrams, or cases, will

execute.

KODA ELECTRIC Hardware-in-the-Loop Tester

The Challenge: Developing a hardware-in-the-loop (HIL) simulator for a main drive locomotive to test newly developed control algorithms.

The Solution: Creating two versions of the simulator based on NI CompactRIO hardware and the NI PXI Express platform with an FPGA card. A core element of the simulator is the model of a controlled system, which was programmed with NI LabVIEW system design software and the LabVIEW FPGA Module. The accuracy of the programmed model was verified by the LabVIEW Control Design and Simulation Module from the same system.
