“The estimated five largest worldwide application markets in 2007 for data acquisition products were industrial maintenance, military/aerospace, off-line production testing/QC and on-line discrete and process manufacturing,” according to a research report from electronics market researchers at More than 20 years ago, PC-based data-acquisition devices were introduced, and graphical programming environments have grown to provide advanced analysis and visualization capabilities.

There also has been significant growth in use of external devices, especially USB PC front ends. As portable peripheral add-ons to computers, they can be moved easily to another platform in a different location. Distributed I/O products with Ethernet connectivity make DAQ easier and inexpensive.

The paperless chart recorder market also is growing. Acceptance of paperless chart recorders by regulators such as the U.S. FDA and EPA encouraged suppliers to add more channels and larger LCD screens.

Then, there are Web-based technologies. According to “Flourishing Trends in Data Acquisition, Monitoring and Logging” (, an article on the Indian business directory, Web-based transfer of data eventually will replace HMI and will facilitate not only acquiring data but also control the operation. “Suppose,” reads the article, “a production manager of a plant receives an alarm on his pager while away from the plant. Instead of rushing to the plant, he goes to the nearest PC and via Internet connection and browser, can access the Web-enabled PLCs or a single-loop controller and take corrective action.”

Then there is wireless. According to “The Future of Data Acquisition,” a white paper from National Instruments, “Wireless technologies have undergone a consolidation and standardization of technologies similar to what occurred for plug-in and cabled PC buses. For high-speed continuous transmission, IEEE 802.11 (Wi-Fi) has seen incredible adoption in mobile computing applications, recently making the jump from your laptop to your Apple iPhone. Maybe even more important for data acquisition applications, vendors have improved the industrial ruggedness of Wi-Fi products. Additionally, IT requirements have significantly enhanced the security and reliability of Wi-Fi networks with technologies such as WPA2 data encryption. Today, Wi-Fi access points can be connected to Ethernet-based data acquisition systems.”
