Research was undertaken to gain a better understanding of Control Engineering subscribers’ applications and needs regarding Data acquisition hardware or software.

Executive Summary

  • Among those specifying, recommending, and/or buying Data Acquisition hardware or software, 77% do so for in-plant requirements and 43% buy for OEM needs.

  • Thirty-two percent of respondents said SCADA is their primary application for DAQ hardware and software, followed by testing and diagnostics with 23%.

  • On average, respondents need their data acquisition system to collect 6,941 variables per minute.

  • Over half of respondents report 16 bit resolution is adequate for their data acquisition needs.

  • Over one-fifth of respondents said 1% to 3% of their data acquisition applications use wireless technology.

  • Fifty-three percent of those surveyed use Networked PLC data acquisition platforms.

  • Seven in ten respondents use Windows XP as their data acquisition operating system.

  • Of those survey participants who use networks for implementing data acquisition applications, seventy-eight percent use Ethernet TCP/IP.

  • Rockwell Automation tops the list of data acquisition hardware manufacturers purchased from in the past 12 months. Twenty-five units of data acquisition hardware was the average number each survey participant purchased during the past 12 months. The average spending per respondent in the past year was $127,936.

  • Over half of respondents report their purchases of data acquisition hardware will grow in the next 12 months, while only 3% expect a decline. o Respondents purchasing behaviors of data acquisition hardware have remained the same in the past two years and should do so for the next two.

  • The most important factors under consideration when selecting data acquisition hardware are ease of use, availability, and technical support.

  • External rack/module and USB are the most preferred form factors for data acquisition hardware.

  • Sixty-five percent of those surveyed say their data acquisition applications require remotely located I/O.

  • On average, respondents typically require 61 I/O points at each remote location.
