While we can¹t say that this ubiquitous networking technology can be found everywhere in manufacturing, it is no longer surprising to hear of an engineer seriously considering it for the next project‹or even for a retrofit.

When our series Editor Terry Costlow went out for research for this piece, the surprising element was all the varieties of Ethernet that he found. While some companies prefer to use ³standard² Ethernet, meaning the common protocol stacks and physical layer used in business and home networks. Others have tweaked the stack in one way or another in order to optimize it for a particular set of applications, or perhaps to gain a competitive advantage rather than use a network favored by a rival.

These differences lead to a variety of arguments about who is truer to the standard, or whose network requires ³proprietary² hardware or firmware. These debates may be entertaining to editors, but they can be downright confusing to engineers trying to figure out the best way to implement a new project. Read more



Ethernet¹s Not the Only Game in Town - There’s more need for tools, but they must measure up.

Ethernet continues to expand its role in the factory, but it¹s facing some stiff competitors as it stretches down to the input/output (I/O) level. When engineers need to connect sensors and other simple components, they¹ve got a number of alternatives that are often more cost-effective than Ethernet.

A range of architectures provide the low cost and performance needed for I/O connections. At the same time, wireless technologies are addressing ease of use, eliminating the difficulty of routing wires every time equipment is moved or new gear is added. Though skeptics scorn the reliability of sending signals through the air of a noisy factory, there¹s little doubt that wireless is going to play a solid role in the factory of the future.

Ethernet will also hold a significant role in data gathering. It¹s dominating as a central network when production facilities are upgraded, bringing compatibility with the front office. A number of companies are now eyeing the large number of I/O nodes that fill today¹s factories, hoping to displace the fieldbuses often used to link these nodes to Ethernet or other factory-wide backbones. Speed is a key weapon in their arsenals.

³We¹re betting the farm that Ethernet to remote I/O is the way to go. With today¹s switched networks, speed is not an issue. It takes less than a millisecond to send a message,² says Tom Edwards, senior technical advisor at Opto 22, a Temecula, Calif.-based vendor... Read more



Software Tools Manage Data Flow - As communication technologies move toward seamless integration for an enterprise, automating data gathering and data movement is coming into the spotlight.

Humans don¹t want to think about the data being gathered until it suits their schedule, or when problems require immediate attention.

Setting up a honeypot requires only an inexpensive Windows personal computer (PC). Set-up and monitoring are the key aspects of getting a honeypot working. In a factory floor network, these PCs should be set up to look like a typical node.

ILS Technology is one of the companies tackling this challenge, providing software that helps automate the data flow. Its DeviceWise tools make it simple to set up reporting structures and quickly set or change the data that¹s gathered from various nodes.

"Without programming, people can select the payloads they want to send upstairs, for example. You can pick things like the high, low or average of 50 variables you want to monitor every 10 minutes and send that data up to the enterprise,² says Fred Yentz, chief operating officer at ILS, of Boca Raton, Fla.

Much of the benefit comes from transferring data from equipment on the plant floor up to the front-office systems. However, data flows both ways. ³It isn¹t just data collection that¹s uploaded. We can receive instructions from the enterprise side and do something downstream,² says John Keever, chief technology officer at ILS... Read more
