Whitepaper
Benefiting from Industrial Ethernet at the Device Level with Smart Remote I/O and Peer-to-Peer Technology
Summary: There can be too much of a good thing, or so goes the old saying. Fortunately, new technology can come to the rescue, at least in certain cases. For example, an industrial enterprise can grow too big for efficient automation control using traditional technology. However, advances in industrial Ethernet can provide a solution, if such techniques as smart remote I/O and peer-to-peer technology are implemented. The result could be better and more flexible control, along with a change in the way Ethernet is used. This white paper discusses the benefits of Smart I/O and Peer-to-Peer Technology.

Best Practices for Networking Automation Computers
Summary: Automation computers can be anywhere, and do very many things. Modern automation computers are connected to networks that may be connected to other networks throughout the plant, and via TCP/IP to the entire world.

Enabling Serial Devices in High Availability Manufacturing
Summary: Today, manufacturing organizations world wide are working on reducing complexity in the manufacturing process and increasing the transparency of processes throughout the enterprise. The ability to communicate data from any part of the enterprise to any other part of the enterprise is core to making modern manufacturing work. This white discusses the use of Ethernet serial devices in manufacturing.

Chasing Moore’s Law – The Truth Behind the OS and CPU Upgrades for Industrial PC Users
SUMMARY: The COTS effect has been almost as big a revolution as that signaled by the phrase uttered by Alexander Graham Bell, “What hath God wrought?” COTS is a three letter acronym that stands for “Commercial, Off The Shelf,” and the COTS revolution has changed commercial computing, created personal computing, impacted telecommunications, and made huge changes in the industrial environment. Most of these changes have been incredibly beneficial. Some have made technologies practical and affordable for applications that were unthinkable thirty years ago. Some have been problematic and some have caused significant FUD. (FUD is another three letter acronym, standing for Fear, Uncertainty, and Doubt.) This white paper discusses the effect of the ever-changing OS on industrial computers.

The Advantages of Small Form Factor HMI
SUMMARY: As embedded computers have become ubiquitous, so too the need for human machine interfaces has grown. Once found in only complex control systems, like distributed control systems in refineries and other process plants, HMI systems are now found in many guises and many locations, from games to industrial machines and tooling systems, with many stops in between. This white paper addresses the increased demand for Small Form Factor HMIs and how they are being used.

Embedded Hardware and OS Technology Empower PC-based Platforms
SUMMARY: Everywhere we look we find computers. Many of them don't look like traditional desktops, or laptops. In industrial infrastructure, we find them in displays, in networking appliances, in machine controllers, in HMIs and in industrial controllers and PACs (programmable automation controllers). We find them in low power, portable devices, and even in field transmitters.

The Evolution and Elements of Robust PC-Based Control
SUMMARY: The combination of declining PC prices and increased robustness of operating systems and softlogic control applications have resulted in enormous growth in PC-based control since the mid-1990s. But while the basic PC is standardized, not all PCs are equal – particularly when it comes to operating reliably in industrial environments...

Windows XP for Embedded Applications
SUMMARY: The embedded version of Windows XP is a componentized version of the well-known Windows XP Professional operating system. Instead of everything being wrapped tightly into a single package, XP Embedded breaks the OS down into more than 10,000 individual components, allowing developers to create systems that have the functionality and familiar features of XP.

Programmable Automation Controllers Find Their Niche...Everywhere!
SUMMARY: In the beginning there was the relay and the timer. And in the process industries, there was the hardwired controller. Then, there was the Programmable Logic Controller (PAC). Today, it's the Programmable Automation Controller (PAC).

Get on the Bus: USB in Industrial Applications
SUMMARY: For industrial automation users, technology giveth and taketh away. On one hand advances in semiconductors and software result in smarter and more capable computer and machines, making the job of automating a process easier and more robust. On the other hand, those same advances spell trouble. The answer to this question maybe the USB.

High Bright Displays...Get The Picture!
SUMMARY: In the old adage, seeing is believing. In today’s modern industrial applications, seeing is more than that. It’s the essence of control, since the human machine interface (HMI) involves the presentation of visual information. That’s why there’s such a demand for high bright displays in highly customized industrial computers and in stand alone industrial monitors.

Gigabit Ethernet: Meeting the Future with Increased Bandwidth
SUMMARY: Much has been written about the use of Ethernet in manufacturing. Ethernet has been around a long time. For computers and networking, it has been around practically forever. One of the great benefits of this fact is the time-tested and de-bugged nature of the Ethernet protocol for networking. Since the mid-1990s, Ethernet networks have become ubiquitous. They are used in offices, in homes, in workplaces, in building automation, and with increasing dominance, not just frequency, on the factory floor.
