Users Seek Color, Flat Panels, High-Light Readability
Color, touchscreens, visibility in high-light conditions, and environmental protection are features a majority of users find important for operator-interface terminals, according to a recent Control Engineering survey. Use of flat-panel screens for operator interface terminals is growing, from 40% in the present purchase to 50% for the next purchase.
Color, touchscreens, visibility in high-light conditions, and environmental protection are features a majority of users find important for operator-interface terminals, according to a recent Control Engineering survey. Use of flat-panel screens for operator interface terminals is growing, from 40% in the present purchase to 50% for the next purchase. Use of "open networks" for operator interface terminals, present versus next purchase, jumps from 39% to 60%.
Control Engineering mailed a survey on operator interface terminals to 1,500 readers on July 20 and concluded the tally on Sept. 24, 1998, with 424 (28.3%) responses.
Results that follow are based on the 97% of respondents involved in specifying, recommending, and buying operator interface terminals. Most, 55.9%, buy, specify, or recommend operator interface terminals for in-plant requirements. Additionally, 34.7% of respondents are involved with OEM requirements; 6% are involved with both.
Primary applications are 37.6% continuous processing, 19% discrete products-manufacturing, 15% supervisory control and data acquisition, 11% batch processing, 5% both continuous and batch, and the remaining other or no answer.
Respondents reflect the wide mix of more than 60 industries that comprise Control Engineering readers. Forty-two percent of respondents are connected to a network, and 39% use a stand-alone operator interface terminal. Twenty percent of the respondents indicate they use both a stand-alone operator interface terminal and are connected to a network.
This vs. next terminal
Among respondents, 51% have OI terminals with NEMA 12 rating, but fewer, 39%, find a high level of protection important for the next purchase. About the same have and will seek a NEMA 4 or 4X rating at 46%.
Regarding communications, 57% of respondents have operator interface terminals with serial communications, dropping 40% for next purchase. Use of "open networks" grows from 39% to 60%; proprietary networks drop from 41% to 25%, present versus next OI terminal.
In the quickly changing world of software, 26% indicate desire to use Microsoft's (Redmond, Wa.) Windows CE operating system for the next OI terminal purchase; 24% want a web browser; and 16% want the next purchase to be enabled with Java from Sun Microsystems (Palo Alto, Calif.).
A total of 166 respondents purchased $12,635,000 in operator interface terminals in the past 12 months, an average of $76,114 per respondent, and $3,375 per unit (3,744 units). Top three vendors in dollar amount and number of units sold are Rockwell Automation (Allen-Bradley, Milwaukee, Wis.), ABB (Rochester, N.Y.), and Eaton/Cutler Hammer Automation (Milwaukee, Wis.). (See table.)
Thirty-seven percent of respondents say the number of purchases for operator interface terminals will be about the same in the next 12 months; 33% anticipate purchases will increase; 25% are uncertain.
Customers demand ease of use
Mark Hobbs, a Rockwell Automation product manager for Allen-Bradley, Operator Interface, Rockwell Automation, says the survey results confirms trends he sees. As flat-panel displays become more cost effective, users plan to their thinner profiles to reduce panel size and display higher-end graphics with more animation, Mr. Hobbs says. Touchscreens also have been gaining ground over keypad configurations, he says. Incorporating Microsoft Windows CE and same configuration software from low-end message displays to high-end graphic terminals will make future offerings more attractive, Mr. Hobbs suggests.
Jim Thorp, OI line product manager, Cutler-Hammer (Westerville, O.), agrees that users are seeking the same software configuration environment across all OI hardware levels. Standard Microsoft operating systems ease communication difficulties; Windows CE allows cost-effective diskless terminals because of smaller memory requirements. To help users keep an increasing number of touchscreens clean, plastic overlays can be peeled off and discarded when dirty.
Marty Richards, product manager, ABB Industrial Systems Inc. (Rochester, N.Y.), says, "As control systems become more heterogeneous, with multiple components from different vendors, customers need their control system hardware to be versatile enough to work with a number of components and systems. This reflects how these products are actually used in real life. Therefore, the need for open systems and components is more important to customers now than it has ever been."
Ralph Damato, Xycom (Saline, Mich.) product manager for industrial PC products and HMI, sees OI terminals diverging along two paths—Windows CE and Windows NT operating systems, for HMI and PC-based control. Mr. Damato first announced to Control Engineering on Nov. 3 that Xycom and Wonderware agreed to package Wonderware's InTouch HMI with Xycom hardware, see below.
