PROFINET over SPE makes Industrial Ethernet Simpler, More Compact, and Future-Proof
Instead of the traditional 8 wires, Single Pair Ethernet requires only a single wire pair. This means less cabling effort, smaller cable diameters, more compact connectors, and greater flexibility during installation - especially where space is limited.
At the same time, SPE enables end-to-end Ethernet-based communication from the sensor all the way to the cloud, reducing media breaks and gateways. As a result, users benefit from a simpler network architecture and consistent data transmission across all levels of automation.
Ethernet-APL also uses a single wire pair and brings Ethernet into process automation and even into hazardous areas—including end-to-end communication all the way to the field device.
The best part: PROFINET over SPE remains PROFINET. All familiar advantages, such as diagnostics, engineering, interoperability, and standardized communication, are retained. SPE extends PROFINET with a more streamlined physical transmission.
PROFINET over SPE combines the proven strengths of PROFINET with the advantages of streamlined single-pair cabling - thereby laying the foundation for the next generation of industrial Ethernet communication.
