  • Etherbus Industrial Fieldbus Solutions with PoE
    solution, if your requirements fit their profile. Profibus was created to entice you to buy Siemens products. Foundation Fieldbus exists to compete with Profibus. Devicenet is a great way to connect limit switches to a Rockwell system. And all of these Fieldbus schemes use their own protocol
  • Which bus, when?
    companies. Profibus is the world's most widely used industrial network. Recognized by its characteristic purple cable and based on RS-485, it is associated with Siemens and is dominant in Europe and South America. Although recent revisions to the protocol have added configuration, diagnostic
  • Various Interfaces for Rotary Encoders
    transmission rates up to 10 Megabytes per second and cable lengths up to 1200 meters. Fieldbus Interfaces (such as Device Net, Profibus, Ethernet, CanBus, Interbus, etc.) Fieldbus communication is very cost efficient alternative to the above technologies. How it works: The automation components communicate
  • A better approach to decentralized control
    for the process-control industry and are not optimized for motion control. Process control has neither the high frequency nor strict determinism required in many motion-control applications. As a case in point, look at fieldbuses such as CANbus and Profibus. They are widely used for discrete I/O control
  • Encoder Resolves to within 5 arc-sec
    the signals outside, there is no concern about susceptibility to noise and EMI. The Dignalizer supports most major bus system outputs, including SSI, CANopen, DeviceNet, and Profibus, as well as RS-485 outputs. It offers both cable and radial-connector configurations and has 12-mm hollow-shaft
  • Tales from the Front: Applying Fieldbus at Genzyme, Part 1
    points. The buses selected for our facility fall into two distinct categories powered buses, including Foundation fieldbus and AS-i bus, and unpowered buses (Profibus-DP and DeviceNet). The powered bus includes the communications and device power on the same wires. The overall topology used
  • Industrial Ethernet made practical
    . It works as a stand-alone machine controller or as part of a PC-based system. It is also compatible with Profibus. An interesting problem emerged recently when a manufacturer tried to install an Ethernet on its factory floor. Despite the efforts of a technical staff that included several Ph.D.-level
