Operator Interface Outlook Clear, Bright
Operator interface terminals (OITs) come in a near-infinite variety of styles, shapes, sizes, colors, and personalities. They continue to proliferate on the plant floor—and beyond—through added features and functionality that help increase the efficiency and precision of operations. This healthy state of the OIT market is confirmed in a recent online study by Control Engineering and Reed Research Group. Includes user advice, and more than 20 photos and graphics.
Operator interface terminals (OITs) come in a near-infinite variety of styles, shapes, sizes, colors, and personalities. They continue to proliferate on the plant floor—and beyond—through added features and functionality that help increase the efficiency and precision of operations.
This healthy state of the OIT market is confirmed in a recent online study by Control Engineering and Reed Research Group conducted earlier this year. The views and opinions of the more than 350 respondents show that OIT products continue to be a critical part of the manufacturing operation, taking on more (and more complicated) tasks.
Results support many trends revealed in the previous study, conducted in 2006, such as the move toward flat panels and away from CRTs, and an increasing interest in wireless and open networks. Based on verbatim comments offered by respondents, in general they consider price important, but also say that OITs are not a place to try to save money. Many good choices exist for OITs, they insist. However, obsolescence can be an issue, with some warning prospective buyers to seek systems that will be viable several years down the road. Others caution buyers to look for specific features needed for the application, and not assume that one size fits all.
Focus on applications, features
Of this group of respondents, more than half apply operator interfaces primarily for in-plant needs (59%). About a fifth (21%) said they specified, recommended, or bought OI terminals for OEM (resale) requirements, while about as many said they do so as a system integrator. A large majority (86%) said they used the products for a variety of manufacturing situations including: industrial, commercial, agricultural machinery (18%); instrumentation, measurement, control systems, and related devices (16%); food and beverage (13%); chemical (13%); and pharmaceutical (11%).
The survey probed in detail respondent attitudes about features: those currently used and those planned or anticipated. In each case, the survey asked respondents to consider features in five areas: NEMA ratings, physical factors, operating system and programming software, communications, and applications and software support.
Looking at NEMA ratings, most respondents indicated they currently used NEMA 12-rated (53%) and NEMA 4/4x-rated (56%) equipment. About 20% said they wanted NEMA 12 equipment in their next terminal; 25% said they would specify 4/4x-rated equipment in the future. More than a dozen physical factors were reviewed by respondents. Most frequently noted features already in use included color (73%), flat panel LCDs (67%), touchscreens (67%), graphics capability (62%), readability in bright ambient light (48%), and a display separate from the controller (46%).
When asked what features they wanted most in their next terminals, respondents put readability in bright ambient light at the top of the list (54%), followed by readability from a distance (46%), larger screen size (45%), flat panel LCD (43%), graphics capability (41%), and touchscreen (40%). (See bar chart.)
Afforded the opportunity to offer comments about features, a number of respondents noted that they look, in particular, at factors such as screen size. Larger screens, said several respondents, enhance visibility, and color has become a requirement in most applications. Added one respondent, “Environmental concerns are considered first—such as resistance to vibration, heat, cold, water—then the programming environment, size, color. It has to hold up physically in the location in which you are going to use it or everything else is moot.”
Operating systems and software
Users say they want bigger screens, readability at a distance and in high ambient light, ruggedness, and wirelessness.
When asked about operating systems and programming software, respondents said they used PLC drivers (61%), Microsoft Windows XP (49%), and CE (23%) most in their current systems. Microsoft Windows XP (37%) and PLC drivers (37%) also topped the list of technologies desired in future OITs, but integrated databases (19%) and Linux (12%) were also well represented.
In the communications area, technologies most frequently cited as currently in use included serial (45%), proprietary network (35%), and OPC (34%). When looking at communication features for future terminals, however, only OPC scored among the top three at 22%. First on the wish list for future purchases was wireless at 40%, followed by open network at 32%.
In the area of applications and software support, respondents overwhelmingly have alarms and trending (72%) and graphics animation (56%) in their current terminals. Also noted were multiple spoken languages (21%), multiple programming languages (21%), Web browsers (19%), and thin clients (14%). Looking to the features sought in the future, alarms/trending and graphics animation again headed the list, each cited by 40% of respondents.
In other feature-related areas, the most respondents (35%) put the typical number of I/O points (tag references) for their OIT applications at between 101 and 500. Twenty-eight percent said the typical number was 100 or fewer. About 38% said their applications had more than 500 I/O points, with 18% falling in the 501-1,000 range and 16% in the 1,001-10,000 range. Only about 4% of the respondents said they had applications with more than 10,000 I/O points.
When asked about certifications and classifications, respondents noted UL listing (87%) as the one found most often in their current OITs, followed by CE mark (47%) and CSA designation (34%). They also cited UL-listing (72%) as the most often desired certification for future equipment, with the CE mark the choice of 35%. Twenty-seven percent said they would seek Class 1, Div. 2, while 25% would seek Class 1, Div 1 ratings in future systems. Currently, only 16% have Class 1, Div 1 rated equipment and 17% have Class 1, Div. 2 rated systems.
In the past year, nearly all respondents purchased at least some operator interface terminals, with the median level at just over 9.5 OITs per respondent. In terms of dollars, nearly 60% spent up to $20,000 on OIT equipment in the past 12 months. The median spending level was just over $16,000. (Detailed data breakdown are in the full report, available online.)
Looking at future spending, most respondents (51%) expect purchasing patterns in the next 12 months to remain about the same. However, 34% expect spending to increase, while only 14% expected it to drop.
The survey also asked respondents to provide details about how their spending patterns for certain OI terminal features have changed in the past 5 years, and how they expect them to change in the next 5 years. The largest segments said their spending has stayed steady for dedicated terminals (67%), thin clients (60%), keypads (58%), and wireless capabilities (55%); however, they have been buying more network enabled OITs (63%), color (58%), touchscreens (55%), and graphics (52%). In the future, outlays are expected to remain the same for dedicated terminals (58%), keypads (54%), color (46%), and thin clients (45%); however, significant numbers of respondents indicate they will be spending more for network-enabled (73%) and wireless (68%) capabilities, and for touchscreens (62%). A majority indicate that expenditures for color (53%) and graphics (54%) will also increase.
In the next 5 years, respondents anticipate spending more on wireless capabilities, touchscreens and network enabled features.
Narrowing your choices
The current market provides a lot of choice when it comes to OIT vendors and models. Respondents, overall, recommend looking for easy to use, easy to program OITs with quality graphics and connectivity capability. Versatility is important. Ease and flexibility of set-up and use rate high. Ease of training operators is also a consideration.
Advice varied when it came to choosing specific OITs: “Select equipment based not only on its ability to perform, but also on how effectively it makes information available to the operator, and how effectively it informs the operator of his options,” suggests one survey participant. “Choose an application based on performance and reliability,” says another, adding: “Choose what is best for the application, not the latest, greatest thing on the market.” Says yet another: “Do not limit yourself. You will use more points than you think you will when developing an application.”
More specific comments recommended users select “an interface that can be run from a bootable memory card so that disaster recovery is easy, even when custom programming is present”; “make sure your display is readable outdoors in bright sunlight”; make sure the system has available drivers for the application”; and “pay attention to heat dissipation in enclosed environments.” Another respondent reminded users that global needs are expanding for many: “If you have global needs, look for equipment that offers global products and that handles multiple languages well.”
Many respondents appear to have an eye on the future and recommend that others look ahead as well. “Make sure you can update and expand,” advises one. Offers another, “Email clients and Web browsers are very useful tools for plant-wide visualization and remote alarming/monitoring applications. Although these may not be requirements in your facility today, they certainly will be in the future.”
