Foxboro introduces touchscreen LCDs for process control

Foxboro, MA—Foxboro Automation Systems, a unit of Invensys, reports that it has further enhanced the human machine interface (HMI) capabilities of its I/A Series automation system with new flat-screen liquid crystal display (LCD) monitor options.


Foxboro, MA— Foxboro Automation Systems , a unit of Invensys, reports that it has further enhanced the human machine interface (HMI) capabilities of its I/A Series automation system with new flat-screen liquid crystal display (LCD) monitor options. This includes a new touchscreen option for Foxboro’s 20-inch LCD monitor that combines the benefits of LCD technology with the superior intuitiveness of touchscreen operator interaction.

“The latest LCD display technology offers many clear and compelling advantages over conventional CRT display technology for process control applications,” says Steve Young, Foxboro’s VP at Invensys. “LCD displays improve visual work performance, eliminate distortion and flicker, and reduce glare and associated eyestrain to help increase operator productivity and well-being. Compared to conventional CRT technology, LCD displays also take up a much smaller footprint in control rooms, and use as much as 60% less power. What’s more, unlike CRTs, LCD monitors do not emit electromagnetic interference, a feature that is particularly important in many industrial applications. For these reasons and more, Foxboro is moving toward an‘all-LCD’ monitor for the I/A Series system. This includes what, to the best of our knowledge, is the process control industry’s only touchscreen option for LCD monitors.'

In addition to being used in all new I/A Series systems moving forward, cost-effective upgrade options are available to allow most current I/A Series system users to upgrade their outdated or aging CRT monitors to the latest LCD monitor technology.

“Foxboro is committed to leveraging appropriate commercial off the shelf technology (COTS), such as LCD monitors, to the greatest possible extent to reduce costs for our customers and help improve the performance of their plants,” adds Young. “Our recently introduced, self-healing Mesh control network for the I/A Series system is another example. This incorporates commercial switches and fiber-optic components in robust and secure industrial configurations to dramatically boost both performance and availability. “At Invensys, we’re convinced that the intelligent use of appropriate commercial technologies is one of main reasons why we’ve been able to maintain the technological leadership of the Foxboro I/A Series system over time.”
