Ethernet - the future of industrial communication

The increasing number of control components, actuators, and sensors in industrial automation gives rise to more complex control networks. Industrial communication in the future will be characterized by highly cost-effective networking of these automation components with the Ethernet standard, adapted to meet the requirements of industrial automation.

Specialized fieldbus systems were initially used to simplify networking. Fast Ethernet technology, however, replaces these systems and offers many benefits:

  • Recognized, forward-looking technology
  • 10 to 100 times higher data throughput rates than with fieldbuses
  • No expensive or proprietary hardware required
  • Standard components such as double-shielded CATSe copper cable, connectors, and controllers in high quantities (e.g. FPGAs)
  • Broad-reaching IT concepts with an integrated transmission medium from office to field level
  • Flexible and compatible automation systems thanks to international standardization
  • Possibility of global networking for diagnostics and maintenance purposes

Profinet

The embedded Profinet module is optimized for use in intelligent automation devices such as drives, control terminals, industrial scales, and control systems. It is typically seen in applications that require large quantities of data to be transferred at high throughput rates together with isosynchronous cycling.

  • Parallel 2 KB dual-port Ram interface
  • Profinet baud rate: 100 Mbit/s
  • Profinet real-time functions and IT functions can be simultaneously used
  • Max. of 512 bytes of cyclical Profinet input and output data (depending on the type of welding controller)
  • Dynamic Web server
