Standardized PROFINET over SPE

PI (PROFIBUS & PROFINET International) is developing an integrated PROFINET over SPE solution - from plug to data link - and the design is being submitted for international standardization.
PI (PROFIBUS & PROFINET International) has announced new development of a PROFINET over SPE solution that advances use of Single Pair Ethernet (SPE) – a plug connector for industrial automation.
A new harmonized SPE connector system with its future-oriented design has been implemented based on key application requirements and is now being submitted for international standardization. It offers a standardized mating face for applications in the control cabinet, in the field and also for hybrid installations, creating the connecting element and paving the way for a universal SPE standard. For the industry, this new generation is a further step into the future. Many manufacturers have announced their plans to begin implementation in the near future.
Standardization work on other levels of SPE communication – like a power concept – is also currently in progress, so that a consistent SPE solution can be achieved across all layers.
It will be possible to implement this solution for all SPE applications through the use of international standards, even at higher speeds and independently of PROFINET over SPE. Thanks to PI, its committed members and many PROFINET supporters around the world, automation is becoming more manageable and easier to handle for both users and manufacturers alike. Regardless of whether it is over one, two or four wire pairs (copper) or over a wireless LAN or Fiber Optics, PROFINET is – and will remain – the global market leader in industrial communication and a guarantor of quality, interoperability and future-orientated technologies.
