PRICES FOR HMI software and operator interface (OI) hardware in the discrete and process manufacturing industries have been falling steadily over the past few years, according to industry market researchers at Frost & Sullivan.
Some price declines have been a result of lower-quality, lower-priced imports entering the market, the study states, but maturing market conditions also have played a role.
"There is an increase in demand for web-based HMIs that offer reduced operating costs, notes Frost research analyst A.S. Udayachandra. On the other hand, its created more concerns about company security. The possibility of people accessing vital information and deliberately causing disruption and acts of terrorism raises the need to address the issue of security."
Udayachandra adds manufacturers of new HMI products must provide potential customers with adequate precautionary measures, especially for web-based systems, and that this can be done through infrastructure and access protection measures.
Venture Development Corp. says the North American market for industrial OI terminals totaled $659 million last year, with shipments expected to grow 7.3% to $760 million in 2006. HMI software revenue derived from North American markets totaled $244 million last year, VDC reports, and is expected to reach $281 million in 2006.
Jim Taylor, VDCs industrial automation and control director, says the market for OI terminals was the largest among all the hardware product types VDC studied. This market also is expected to have the largest growth in dollar volume through 2006. The high demand for graphic terminal products is a result of the shift away from graphic monitors, he says, and to some extent from PC-based solutions.
The largest share of these HMI software revenues come from end-user applications, Taylor says, with smaller shares for OEM and system integrator applications. However, a major shift is forecast, with the share for OEM and systems integrator applications expected to be the largest in 2006, according to Taylor.
Similarly, new technologies and form factors are responsible for much HMI software growth, according to market analysis by ARC Advisory Group. Its forecast through 2008 shows the influence of regulatory requirements, such as the U.S. Food and Drug Administrations 21 CFR Part 11 rules and the TREAD act, which demand electronic tracking and tracing capabilities from HMI software. This evolution, says ARC, will continue as HMI software becomes a component of current web-based architectures, and as web services emerge to become the next delivery system for presentation and control processes.
