OEMs Leverage Information for Position, Price

Open Networks Enable Remote Support, Enterprise Integration

Automation Fair 2012

There was a time when industrial manufacturers had large engineering departments that made all the decisions on how their machines would look and operate. But more and more, that breadth and depth of expertise is leaving the building, and manufacturers are instead handing their specs to machine builders and leaving it to them to figure out how to get the job done.

The OEMs, meanwhile, look to their automation suppliers to get the tools they need to ease machine design and development. Much of that is geared toward building smarter machines—more integrated, more sustainable, safer machines that provide the information and diagnostics machine builders and users need. And it needs to be done easier and cheaper in the long run.

"We hear a lot about total cost of ownership, but that's not the right message for machine builders," said Christopher Zei, vice president of the global industry group at Rockwell Automation. "Instead, we need to talk about total cost to design, develop and deliver."

Zei led a discussion among machine builders and users this afternoon at the Global Machine & Equipment Builders Industry Forum as part of Rockwell Automation's Automation Fair in Philadelphia. Panel members discussed the new requirements they face in building smart machines and the way they are tackling those demands.

Diagnostics and Data

The discussion focused primarily on the information and diagnostics capabilities of smart machines—how the OEMs are leveraging the wealth of information that's available on machines today to build competitive advantage or reduce costs.

"Cost is a big deal," said Matt Wicks, vice president of systems engineering for Intelligrated, which provides automated material handling systems. "We're leveraging the technology and integrated architecture to reduce not only the hardware cost, but the engineering cost, and also the cost of servicing the equipment."

Intelligrated not only accesses the data on its machines, but is able to take action to keep those systems running more smoothly. The company gets data out of its high-speed sorters, for example, to recognize problems early. "We monitor the amount of chain sag that we have over time and determine what maintenance needs to happen," Wicks said, explaining that they are able to react to the data and do some tensioning of the chains. "We use this as a competitive advantage."

Focke uses machine data to get a better view of the bigger picture, according to Heino Fecht, automation and design development manager for Focke. The German packaging machine supplier began using PackML, which defines a common language for automated machines. "We have the latest 500 stop codes, so if there's a problem we can see why a machine has stopped," Fecht said, noting that the open standard makes it easier to access codes and correct issues. "We usually can track and sort the most common fault codes and get better performance."

Ethernet Everywhere

Like most, if not all of the panel members, Focke uses EtherNet/IP for machine communications. "We started seven years ago to eliminate other networks, and now we use only EtherNet/IP," Fecht reported. Although it was a bit of a struggle to get employees used to the switch, the move has been good, he added. "Now we're looking to eliminate Sercos."

Spoolex, a French company that makes converting equipment for web-formed products, has replaced DeviceNet and ControlNet with EtherNet/IP and is gradually replacing Sercos with CIP Motion, according to Sebastien LeGris, automation and engineering manager for Spoolex.

Michael Sweet, director of MES at First Solar, agreed that it was difficult to get everybody on board at first, but the move to EtherNet/IP has been a good one. "We've seen a lot of advantages," said Sweet, who brought a user's perspective to the discussion. First Solar makes photovoltaic modules for the solar energy industry and has been able to make use of the integrated logic, Sweet said. In the past, First Solar had to interlock machines to pass the product from one to another. "Now we've created an electronic interlock through EtherNet/IP. All of it is pre-packaged now; very plug and play."
