ControlNet provides bandwidth for I/O, real-time technology–the producer/consumer model. The producer/consumer interlocking, peer-to-peer messaging and programming all on the model permits all nodes on the network to simultaneously access same link. It’s deterministic nature helps assure when data is the same data from a single source. Ultimately, the model provides sent. It’s repeatable performance efficiency because data is produced only once regardless of the does not change that time when number of consumers, and precise synchronization because data devices are arrives at each node at the same time. added to or deleted from ❝The ControlNet architecture The future demands advanced network the network. allows field information to be technology, greater system performance, updated ... without processor and higher productivity.

Based on published material it shows the technical principles of the various approaches and tries to put these into perspective. The content given represents my best knowledge of the systems introduced. Since the company I work for is member of all relevant fieldbus organizations and supports all important open fieldbus and Ethernet standards, you can assume a certain level of background information, too. The slides were shown on ETG Industrial Ethernet Seminar Series in Europe, Asia and North America as well as on several other occasions, altogether attended by several thousand people. Among those were project engineers and developers that have implemented and/or applied Industrial Ethernet technologies as well as key representatives of some of the supporting vendor organizations. All of them have been encouraged and invited to provide feedback in case they disagree with statements given or have better, newer or more precise information about the systems introduced. All the feedback received so far was included in the slides. You are invited to do the same: provide feedback and – if necessary – correction. Please help to serve the purpose of this slide set: a fair and technology driven comparison of Industrial Ethernet Technologies.

  • Real-Time Ethernet – PROFINET Technology
    July 2011 Real-Time EtherNet – PROFINET Technology Author: Advantech E-mail: [email protected] www.advantech.com July 2011 Twenty years ago, there were competing network protocols in the enterprise (office) network space. Today, no one would believe that, because there is only one network protocol that is used in 99%-plus of all enterprise networks. That network is Ethernet running TCP/IP. Figure 1 – Ethernet is ubiquitous in the enterprise WHAT IS ETHERNET? Ethernet is ubiquitous. Our computer networks all are run on Ethernet, even our video games and HD video devices in our homes are Ethernet enabled. So it is very important to understand what Ethernet is, how it works, and what it can and cannot do. This is especially important in the industrial environment, as Ethernet becomes common on the plant floor. Ethernet is a family of frame-based, or data packet based, networking technologies that are part of the IEEE 802.3 standard. There are several varieties of Ethernet. Originally based on a coaxial cable format, like the old analog cable TV cable, Ethernet cabling became based on twisted pair technology adapted from telephony (see Fig. 1), because this kind of cable was already run in many offices and was understandable to most cable installers. Thus, 10Base-T was developed as a star topology, similar to telephony, and this was continued in 100Base-T and other higher throughput formats. Ethernet networks consist of nodes, switches, routers and repeaters. Switches, especially smart managed switches, have made it possible to have Ethernet networks consisting of a nearly infinite number of nodes.

    Connected Building WEBs BUILDING AUTOMATION SYSTEM MAKES INTEGRATION SMOOTH AND EASY Lake Trust Credit Union Headquarters of Brighton, Michigan Two things simplified the system integration: early WEBs Building “collaboration in the planning stage and using WEBs. Automation System – Alan Putnam, Area Operations Manager, ControlNET LLC ” Case Study © SmithGroup JJR and James Ewing Early Collaboration Leads to Long-Term Success © SmithGroup JJR and James Ewing Most of the time, contractors are brought in after much of the planning has been done, forcing the contractor to make compromises that might not be the best for the building. Fortunately for ControlNET, they got in on the early planning stages of the new headquarters for Lake Trust Credit Union. Lake Trust, based in Brighton, Michigan, wanted to build a new headquarters facility that would attract workers and help them enjoy coming to work, but that also wouldn’t sacrifice energy efficiency as LEED certification was an important goal. Breaking barriers is part of the Lake Trust philosophy, and they wanted the facility to reflect their commitment to openness and collaboration. As it turned out, that same spirit of collaboration was the key to the building’s smooth development, construction and operation. TEAMWORK ENSURES THE BEST SOLUTIONS The project included a Collaborative Integrated Design Build Team that brought together the architects, general contractor, power and mechanical contractors, and ControlNET as the systems integrator and temperature controls contractor. “Being part of the team from the start made us a resource rather than a vendor,” said Alan Putnam, Area Operations Manager for ControlNET. Working together helped us create solutions and ensure from the start that all systems would be“ seamlessly integrated.
