The Foundation of LabVIEW: Virtual InstrumentationAutomation through software led to a realization about fixed-functionality instrumentation…

Redundancy: DisplaysInstrument vendors provide a limited-

quality display per instrument, even though

monitor technology is far more advanced.

Redundancy: Processors

Chip manufacturers rapidly enhanceprocessors according to Moore’s law, but

instruments have fixed processing power.

Redundancy: Memory

PCs can quickly capitalize on a performance

boost from a memory upgrade from readily

available RAM.

Redundancy: Storage

Each instrument duplicates onboard

storage even though PC hard drives are

plentiful and cost-effective.

Redundancy: Power Supplies

Each separate instrument requires its own

power supply to run measurement circuitry

that captures the real-world signal.

The Foundation of LabVIEW: Virtual InstrumentationBy leveraging COTS PC components, the software becomes the instrument

LabVIEW unlocks the power of instrument and data acquisition hardware

by capitalizing on the PC industry and abstracting redundant circuitry.

is ideal for programming parallel data acquisition

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)

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

don’t have any data dependencies.
