The human-machine interface (OI) - is increasingly moving in a more detailed, more effective, more powerful direction. Today's operating interface systems are more complex than ever and provide more precise monitoring and control of the processes they monitor. Its function can be from a PLC terminal to a powerful processing platform. In its basic form, the interface can do data processing, and can send information to operators in any way, from text information to vivid graphics. Today, due to the advancement of technology, the scale of application is also increasing. Although OI is being developed to meet more needs, users continue to make more demands.
The Reed Research Institute recently conducted a survey of ControlEngineering readers, who were very knowledgeable about the rapid growth and widespread use of these products. Of these, 246 were involved in the survey. Almost all of them expected their demand for operating interface terminals to increase (46%) or remain flat (49%) in the next 12 months. Only 5% is expected to decrease. For OI's understanding of their demand growth rate, nearly three-quarters of these demand growth is expected to be between 1% and 30%.
Technology development and advancement in connectivity are the main reasons for application growth. The use of Ethernet, PC-based technology in embedded form, and enhanced diagnostic capabilities have all contributed to the rapid growth of the market. Clyde Thomas, business product manager for human-machine interfaces at Eaton Electrical, believes that "in fact, the use of human-machine interfaces It is being driven by more intelligent devices, including mechanical vision systems, sensors, actuators, and power control devices that can communicate with the PLC."
George Liao, Product Manager at Advantech, believes that the widespread use of Ethernet gives OI more opportunities to apply. At the other end of mature Ethernet, OI systems include customized platforms, remote control/monitoring and lower costs. He pointed out that “For these PC-based OI products, the market forecast is to have double digits in 2005. increase."
A stable platform According to Reed's survey, the use of these devices will remain constant, close to the findings of last year. The survey shows that the users who use the most OI products, nearly 49%, are in the continuous manufacturing and batch manufacturing industries. Of these, 16% were used for continuous manufacturing applications, and it is worth noting that it was a 3% drop from last year in the past year. Followed by discrete manufacturing accounted for 15%. Batch processing and manufacturing accounted for only 7% of the application. The remaining major piece of 13% is used as an important OI terminal application.
The purchasing model also reflects its continuity. In the past five years, 94% of respondents purchased the same number or more personal computers. At the same time, many people purchase more or the same number of touch screens (90%), enhance color acceptance capabilities, and add graphics or networking systems.
Looking at the next five years, 90% of respondents said they plan to purchase more or at least the same number of personal computers as they used to. 97% of people said they added the same or more touch screens for the operation, 97% will increase the same number or more of color touch screens, 96% will increase the drawing ability of the same level or more, and 96% will Purchase more or at least the same number of OIs with networking capabilities.
The most interesting phenomenon has emerged in the thin client and wireless OI fields. In both cases, 90% or more of the respondents said they expect to purchase the same or more wireless or thin client interface devices in the next 5 years. Eighty-two percent think their product purchases in these areas have remained unchanged or have slightly increased over the past five years.
In the past? Or buy it now?
OI is a well-recognized and diverse system, and today's growth is faster than ever. The list of respondents’ wishes is shown in the figure. Although most of them already have systems with multiple options, they still want more features. A few of the key issues are: 2/3 of the respondents hold flat-panel displays, and more than half expect their next OI to be flat-panel displays. At the same time, the wish list also shows readability under a certain contrast and brightness and ambient light, and about half of the responses show the attention to these characteristics.
If the response is accurate, at least part of these wishes are very likely to be achieved. Paul Daugherty, OI product manager at GEFanuc Automation, believes that more users will use OI products outdoors. He said, "In the future, high-brightness daylight-readable displays close to NITS will appear."
In the field of networked communications, Reed research shows that one-third of users already have an open network, but nearly half still hope to have this networking capability. In terms of software/operating system, nearly 2/3 of them use Microsoft Windows NT. However, 1/3 hope to obtain it in the next purchase. Nearly 1/5 of users use Windows CE, and 20% want to use Windows CE in the next OI. Nearly 20% have used the web browser as the basic software. The NEMA level is still important. Half of the respondents have 4/4X and 12 rated systems, and more than one-third plan to increase this. Less than 20% of the system has no rating.
At the bottom line of these discoveries, GE Fanuc's Daugherty said, “Historically, the user interface was composed of low-cost, low-functionality buttons and indicator lights. Now it is increasingly being used by some high-priced, high-functionality computer-based products. Instead, OI users want products with higher functionality, lower prices, and less system complexity than computers. This will be possible with the advent of Windows CE-based OI products."
The various authentication issues that still exist Various authentications and network options still occupy a certain amount of weight. Investigation shows that application guarantees in dangerous situations are people's concerns. For Class I, Div.1 certification, 16% of the respondents indicated that they already had, but nearly 40% hoped to have it in the future. At the same time, for Class II, Div.2, 18% of the survey respondents already have, and nearly 30% hope to have in their systems in the future.
UL certification is very common, with 85% of respondents saying they already have in their system, and 74% want them to have it in the future. The CEMark and CSA certification did not cause such great concern. About 43% have CEMarK in their current system and only 40% are looking for their future systems. At the same time, 37% have systems with CSA instructions, but only 36% expect to have such certification in their next OI.
In the cyber wars, it was overwhelmingly superior to the investigators' most favored option. Nearly 80% of respondents said they use Ethernet TCP/IP and plan to continue using it for the next 12 months. At the same time there are other options, such as RS-232 (76%), RS-485 (71%) and 4-20mA (63%).
Other accepted networks include FOUNDATION Fieldbus, Profibus, ControlNet, DeviceNet, HART, and Modbus. More than half (53%) use or plan to use DeviceNet, 46% use or plan to use ControlNet, 23% select Fieldbus; 36% HART, 29% Profibus-DP; and close to 40% use or plan to use Modbus or Modbus TCP/IP . One-third of respondents currently use private networks or plan to continue using them for the next 12 months.
What is the future status of the bridge for the OI market? All points to bigger, better and more. Eaton Electric's Clyde Thomas said, "OI vendors need to support greater flexibility in communicating with third-party devices, which will mean more open communication standards are being adopted more quickly. For example, OPC. Balancing costs, performance, and usage Convenience also requires more embedded technology. For users, there will also be some potential opportunities for benefit, but understanding the defects and problems of these new OI platforms requires more training and expertise."
Rick Barnich, vice president of AnnArbor Technologies, believes that future technologies will focus on server-based technology and greater display development. His company, he pointed out that will provide an updated system in a smaller, embedded tablet computer structure, with standard industrial computer settings.
Barnich said, "We are looking into more central server applications, so that the cost of licensing, maintenance and security is lower. In order to fit this structure and keep costs under control, the operating interface is now an embedded Linux or embedded XP clients. In addition, the inherent size and complexity of these applications, the general operator interface display size is increasing..."
In any case, the importance of the operator interface for automatic control is undisputed. Various systems are demanding more and greater automatic control capabilities. Whether it can carry out complex controls and have a wireless network or larger, better displays will be a problem for future OIs.
