A sampling of Control Engineering subscribers involved in buying and specifying industrial network devices often include IT on cross-functional teams, according to research published in April 2007. April issue article by “Product Research: Industrial Networking” cites subscriber survey results and lists related new products from leading vendors.

Research results upon which the article was based include:

• Among respondents who formed and use industrial network cross-function teams, 63% include the engineering department; 40% included members from information technology on their team.

• When respondents were asked for their primary applications for industrial networks, 61% indicated supervisory control and data acquisition (SCADA); 51% cite diagnostics, testing, and maintenance.

• Network hardware devices, network software tools, PLC hardware, and I/O products and systems are the most popular choices for network connectivity now and in the future.Ethernet TCP/IP, 4-20mA, RS-232, and RS-485 are the most popular network protocol selection for now and in the future.

• When asked about the importance of attributes when purchasing industrial network products, 85% of respondents mentioned reliability as the most important factor (top box = very important); 70% mentioned product quality followed by communication capabilities (68%).

• When asked which considerations are important when selecting an industrial network products manufacturer, responsiveness to problems was mentioned by 75% (top box) of participants. Technical assistance was close behind as 74% of respondents mentioned this as being very important.

• I/O devices and connectors garnered the highest level of respondent expenditures last year on industrial network products (mean basis). Wire and cable was second highest with a mean expenditure of just over $77,000. However, most categories witnessed significant investments as determined by the percentages purchasing within the $100,000 or more category.

• For those companies expecting a return, half (50%) expect a return on investment (ROI) of 30% or less for their annual expenditures on industrial network products.Over half (53%) of total respondents indicate the company does not track or expect industrial networks to have an ROI.

• 40% of respondent companies expect an annual savings of greater than $25,000 from their industrial network product investment; 29% of respondents mention their company does not expect any savings; 20% of respondents felt a one to two year time frame was needed to generate anticipated savings from the use of industrial network products.

• Less than half (46%) of respondents use third-party integrators or consultants for industrial network applications.Results vary in terms of how much respondent’s state spending on services from third party integrators or consultants for industrial network applications.
