Customers who have implemented Profibus and/or Profinet are always featured keynoters. And this year was no exception.
Mike Bastian, Controls Engineering Manager at Ford Power Train discussed his standardization, flexibility, acceleration strategy. Profinet became the backbone of his strategy. He stated that standardization on Ethernet and Profinet helped drive controls standardization giving Ford better "control" over its drive train manufacturing operations.
Windenergy行业管理部门负责人Stefan Gallmann讨论了风力涡轮机实际上是如何非常复杂的机器，并且在风车中链接时，它具有相当大的沟通要求。实施专业人士大大简化了典型的风力涡轮机和整个公园的网络体系结构。
Following up two user presentations from day one, Jim Simmons of DuPont presented one of the best, down-to-earth implementation discussions I've heard in my 14 years as an editor. And, despite this being a Profibus conference, he was frank in his evaluations and wound up implementing a mixed fieldbus system.
他是doing controls at DuPont when the company wanted to build a facility at its Fayetteville works to produce PVF polymer in 2005. The project came in $5 million under budget and 2.5 months ahead of schedule. That, in itself, is a miracle. Prior to him, someone had chosen Siemens PCS7 as the preferred DCS system, so he stayed with that.
当时，席梦思对现场布斯网络的了解很少，但他决定调查他们，以查看他们是否可以帮助他的控件实施。他对潜在网络进行了彻底的分析。“有很多。”他死了。他的分析始于查看设备的类别 - 启示，自动块阀，分析设备，电动机/驱动器和远程I/O。然后，他研究了每个类别的要求。
The result was Profibus PA for instrumentation (it worked well with the PCS7), AS-i for the block valves, Profibus DP or Modbus for most of the rest. The company standard for variable frequency drives was Rockwell Automation, and those devices talk DeviceNet. So he used an Anybus connector from HMS to connect Profibus DP to DeviceNet.
Some of the benefits DuPont realized included advantages of initial installed cost, plant flexibility, reduced time for project execution and time for ongoing plant changes.
Simmons concluded that there was not one perfect fieldbus for every possible application, so engineers should select wisely per design requirement. However, engineers should have to justify NOT using fieldbus on a project.
Market Success Touted at PI NA Meeting
According to Executive Director Mike Bryant, both Profibus and Profinet are showing robust growth in North America as well as globally. PI NA leaders, believing that a market inflection point is upon it for Profinet, will be undertaking a more aggressive marketing campaign for that technology in the next year.
