Siemon, a leading global network infrastructure specialist, demonstrated operation of 10BASE-T1L Single-Pair Ethernet (SPE) over 400 meters of TERA® balanced twisted pair copper cabling at the BICSI® Fall Conference in Las Vegas, NV.
Single Pair Ethernet will become a key technology in smart buildings. It is the missing link for connecting devices up to sensor/actuator level by means of a standard Internet protocol (IP). It has the potential to replace existing field bus systems in the Internet of Things (IoT) in buildings or the Industrial Internet of Things (IIoT) in smart factories.
IO-Link and Single Pair Ethernet, two recent networking protocols for improved industrial connectivity
single-pair Ethernet takes the enterprise-class networking protocol and implements robust and reliable device communication over a single twisted pair. Reducing the number of pairs by a quarter reduces cable weight, reduces cable cost, and uses robust industrial-grade widely available connectors. Unlike the serial-based IO-Link, SPE functions as a standard networking protocol and can operate over distances of up to 15 metres using unshielded cables and 40 metres using shielded cables.
Single-pair Ethernet (SPE) is a case where less is more: an Ethernet connection with one pair of streamlined wires rather than two or four pairs. This means power and data can digitally […]
20 meters. That is the maximum distance between an IO-Link master port and an IO-Link device using a standard prox cable. By using SPE, we gain the Ethernet cable length advantage. So, instead of being limited to 20 meters, your IO-Link cabling could stretch to 100 meters! Imagine the opportunities that opens in industrial applications. It is possible that even longer runs will be achievable.
Single Pair Ethernet is taking us toward the IoT goal of Industry 4.0 connectivity in the automation world. Using SPE, endpoint data can be delivered from physical devices to data centres in a super fast and reliable way.
Watch this webinar on demand to learn how SPE can impact future building automation system architectures, simplifying networks, and providing greater access to the building system data that can drive efficiency and provide a more pleasant user experience through building technology.
With the growth of the internet of things (IoT), machine-to-machine communications, building automation sensors and other emerging technologies, there is greater demand for connectivity that can deliver both power and data over longer distances to support these applications. Single Pair Ethernet (SPE) is poised to address these trends, as it combines reliable, economical, lightweight and space-efficient single pair cabling with Ethernet’s non-proprietary protocols for greater interoperability.
Smart buildings promise automated control of the buildings’ operations, which will require sensors that printed/flexible electronics are very well suited to.
