NI CompactDAQ Controllers<\/h2>\r\n\r\n
\r\n

NI CompactDAQ Controllers combine an embedded computer, C Series module slots, data acquisition hardware and industrial communication interfaces in one standalone system. They are designed for applications that require local data logging, measurement, monitoring or control without a continuously connected external computer.<\/p>\r\n\r\n

CompactDAQ controllers are used in distributed test systems, machine monitoring, environmental testing, automotive validation, industrial data acquisition and long-duration sensor logging. They provide a practical middle ground between a PC-connected CompactDAQ chassis and a fully FPGA-based CompactRIO system.<\/p>\r\n <\/div>\r\n\r\n

What Is a CompactDAQ Controller?<\/h3>\r\n\r\n

A CompactDAQ controller is an integrated embedded measurement system. Unlike a standard USB or Ethernet CompactDAQ chassis, it includes its own processor, memory, storage, operating system support and C Series module slots.<\/p>\r\n\r\n

The controller can run acquisition, logging, analysis and communication applications locally. This reduces dependence on an external host computer and allows the measurement system to be installed closer to machinery, vehicles, test cells or remote sensors.<\/p>\r\n\r\n

\r\n

A CompactDAQ controller already includes C Series module slots and embedded processing. It is not normally combined with a separate CompactDAQ chassis. Select the controller according to the required slot count, software environment, processor performance, operating temperature and installed C Series I\/O modules.<\/p>\r\n <\/div>\r\n\r\n

How to Choose a CompactDAQ Controller<\/h3>\r\n\r\n

1. Determine Whether Local Processing Is Required<\/h4>\r\n\r\n

Select a CompactDAQ controller when the system must acquire, log or process data without relying on a continuously connected external computer. This is useful for remote equipment, test cells, mobile installations, long-duration tests and industrial deployments.<\/p>\r\n\r\n

If the application only requires PC-based acquisition near the measurement location, a standard CompactDAQ chassis can be simpler and more cost-effective.<\/p>\r\n\r\n

2. Select Four or Eight C Series Slots<\/h4>\r\n\r\n

Choose the controller according to the complete module plan. Four-slot controllers suit compact systems with a limited number of I\/O functions, while eight-slot controllers support larger mixed-signal systems containing temperature, voltage, current, vibration, strain, digital I\/O and communication modules.<\/p>\r\n\r\n

Leave expansion capacity when future requirements may include additional sensor types, counters, CAN\/LIN interfaces, digital control or spare channels.<\/p>\r\n\r\n

3. Match Processor Performance to the Application<\/h4>\r\n\r\n

Processor requirements depend on more than the data acquisition rate. Consider local data logging, file management, networking, display requirements, analysis, database communication, protocol handling and application code running at the same time.<\/p>\r\n\r\n

Applications requiring frequent analysis, multiple communication tasks or high channel counts generally benefit from the higher-performance controller generation. Test the intended application with representative channel counts and acquisition duration before deployment.<\/p>\r\n\r\n

4. Choose the Operating-System Strategy<\/h4>\r\n\r\n

Some CompactDAQ controller configurations support Windows Embedded Standard 7, NI Linux Real-Time or both, depending on the exact model and part number. Windows is appropriate when the application depends on Windows software, drivers or familiar desktop workflows.<\/p>\r\n\r\n

NI Linux Real-Time is intended for deterministic timing and dedicated measurement or control tasks. Real-time performance depends on the complete software design, timing architecture and I\/O configuration; simply installing a real-time operating system does not make every application deterministic.<\/p>\r\n\r\n

5. Confirm C Series Module Compatibility<\/h4>\r\n\r\n

The controller determines the embedded computing platform, while the installed \u041c\u043e\u0434\u0443\u043b\u0438 \u0441\u0435\u0440\u0438\u0438 C<\/a> determine the signal interfaces. Verify module support, sample rate, channel count, signal conditioning, isolation, connector and terminal accessories for every required measurement.<\/p>\r\n\r\n

For mixed measurements, also confirm how modules share timing and whether simultaneous acquisition is necessary. Temperature logging and high-speed vibration acquisition can have very different timing and throughput requirements.<\/p>\r\n\r\n

6. Review Network, Storage and Remote Access<\/h4>\r\n\r\n

Define how the controller will communicate with the rest of the system. Consider Ethernet network topology, IP management, remote access, cybersecurity requirements, removable storage, local file retention and post-test data transfer.<\/p>\r\n\r\n

For long recordings, calculate storage use before deployment:<\/p>\r\n\r\n

Required storage = continuous data rate \u00d7 recording duration.<\/strong><\/p>\r\n\r\n

Allow margin for file-system overhead, metadata, operating-system space and safe data transfer after the test.<\/p>\r\n\r\n

Software and Deployment Considerations<\/h3>\r\n\r\n

CompactDAQ controllers are commonly configured through NI Measurement & Automation Explorer and use NI-DAQmx for supported I\/O configuration and data acquisition. Application development can use LabVIEW and compatible programming environments, subject to the selected operating system and installed driver versions.<\/p>\r\n\r\n

Before commissioning the controller, confirm:<\/p>\r\n\r\n
