CompactDAQ is a data acquisition platform built by National Instruments that includes a broad set of compatible hardware and software.[https://books.google.com/books?id=NY5yq2R1Se4C&dq=CompactDAQ&pg=PA280 Advanced Aerospace Applications], Springer Science & Business Media, 02-Apr-2011[https://books.google.com/books?id=RDfqp_bPNxEC&dq=CompactDAQ&pg=PA149 Conversion of Large Scale Wastes into Value-added Products], CRC Press, 12-Dec-2013[http://www.ni.com/data-acquisition/compactdaq/ CompactDAQ], National Instruments[https://books.google.com/books?id=TfTCAgAAQBAJ&dq=CompactDAQ&pg=PA41 Sensor Technologies for Civil Infrastructures], Elsevier, 26-Apr-2014 CompactDAQ integrates hardware for data I/O with LabVIEW software to enable engineers to collect, process and analyse sensor data.[https://books.google.com/books?id=DwWcBAAAQBAJ&dq=CompactDAQ&pg=PA441 Mechatronics: Ideas for Industrial Applications], Springer, 24-Sep-2014[http://www.ni.com/compactdaq/whatis/ What Is NI CompactDAQ?], National Instruments CompactDAQ systems are less expensive than equivalent systems within the NI PXI Platform.
Hardware
CompactDAQ systems are managed by a chassis controller module, which controls data transfer between up-to 8 I/O modules and a PC.[https://books.google.com/books?id=IEYkBAAAQBAJ&dq=CompactDAQ&pg=PA92 Operational Modal Analysis of Civil Engineering Structures], Springer, 01-Jan-2014 The chassis controller contains a timing controller that synchronizes data acquisition from all connected I/O modules.[https://books.google.com/books?id=zKKG3ZuOtYgC&dq=CompactDAQ&pg=PA362 Instrument Engineers' Handbook], CRC Press, 19-Aug-2011 The following types of chassis controllers are available:
- USB Chassis - designed for small, portable, mixed-measurement systems on the benchtop or in the field
- Ethernet Chassis - ideal for distributed measurement systems in locations where Ethernet networking infrastructure already exists
- Wireless Chassis - zero configuration setup over Wi-Fi and support for over 50 measurement-specific modules
CompactDAQ systems connect to sensors via wired or wireless I/O modules, connected to a chassis controller. Currently only NI C Series modules are compatible with the CompactDAQ platform. Modules are available with analog inputs and outputs for various sensor and signal types, digital inputs and outputs, built-in signal conditioning and ADCs, and most modules provide electrical isolation.
Software
Sensor data is collected and analyzed using compatible PC software such as LabVIEW, LabWindows/CVI, Measurement Studio and SignalExpress, also built by National Instruments.[https://books.google.com/books?id=-YOmAgAAQBAJ&dq=CompactDAQ+software&pg=PA12-IA28 LabVIEW Graphical Programming Cookbook], Packt Publishing Ltd, 23-Jan-2014 Application programming interfaces are also available for C/C++, and .NET languages such as C#.[http://www.ni.com/compactdaq/whatis/ What Is NI CompactDAQ?, Software Tab], National Instruments
LabVIEW integrates with CompactDAQ chassis controller hardware to connect to physical sensor or signal data sources. LabVIEW can also connect to oscilloscopes and USB DAQ systems using the Measurement and Automation eXplorer (MAX) LabVIEW component.
In LabVIEW, virtual instruments can be configured and simulated, in order to test data processing when physical hardware is not available. The Virtual Instrument Software Architecture (VISA) is the back-end component that manages communication between LabVIEW and CompactDAQ hardware.
NI SignalExpress LE is provided with every chassis controller for basic data logging and analysis.[https://www.ni.com/en-us/shop/compactdaq/what-are-compactdaq-chassis.html], National Instruments NI SignalExpress is a Microsoft Windows application that provides features for acquiring, analyzing, and displaying data from compatible data acquisition devices and instruments.[http://www.ni.com/labview/signalexpress/ SignalExpress], National Instruments
