Networking opportunities with Single Pair Ethernet for CAPIEL manufacturers

Switchgear, controlgear and their assemblies are getting smarter thanks to more powerful embedded electronics. The emerging Single Pair Ethernet (SPE) technology enables these network components to interact with the control systems into which they are integrated. This presentation analyses the potential transformation of industrial communication networks from traditional fieldbus to SPE, as well as the associated challenges and benefits on the market.

The major business trend is the development of industrial internet of things using digital twin information models for increasing the effectiveness of the manufacturing and electrical distribution systems where the increased connectivity and interoperability of switchgear and controlgear plays a significant role, including the flexibility to adapt information exchanges in systems more rapidly. Challenges such as the carbon footprint reduction required by EU regulations and the required new skills should be managed.

Utilizing Single Pair Ethernet in Building Automation

Single Pair Ethernet (SPE) is designed to replace classic serial field installation based on RS-485 or proprietary technology. Two wires, i.e., one wire pair, will be sufficient for seamless connection in the future, from the field device (sensor/actuator) to the cloud and back, using proven IP-based communication protocols, such as BACnet/IP and BACnet/SC, Modbus/TCP or KNX/IP. The advantages are obvious: Seamless communication eliminates gateways; a single wire pair saves weight, space and installation time. With Power over Data Line (PoDL), SPE also offers the option of powering communication devices via the same wire pair.

But what is the right IEC 802.3 profile to make use of it in building automation applications? The companies Belimo, Thermokon and WAGO use this positioning paper to move a step forward and to come to a conclusion.

How an Why to Use Single Twisted-Pair Ethernet (SPE)

Communication in robotics system designs is undergoing a transformation as it keeps pace with the fourth industrial revolution, or industry 4.0. In the status quo, robot communications must be robust, accurate, have excellent timing characteristics and neither hinder axis movement, nor be negatively impacted by it. Several important, but disparate, communication interfaces have evolved to meet the stringent requirements of robotics communications and have done so for many years. Increasing speed and bandwidth requirements from robots is starting to exceed the capabilities of these very effective interfaces. This application note shows what to consider when designing with Single Twisted Pair Ethernet to ensure it fits your system requirements.

Single Pair Ethernet (SPE) in IIoT and BIoT Environments – a Backwards Compatibility Study

What should we do regarding preparations for the employment of Single Pair Ethernet? Can we benefit from Single Pair Ethernet networks right now? Is it possible to make a smooth transition from existing legacy technologies to the bright future ahead?

In this whitepaper, our Working Group Cables investigates how new Single Pair Ethernet cables can be used to carry legacy bus protocols (Foundation Fieldbus, Profibus PA and PB, RS485, BacNet, Modbus, Canbus) and to what extent old cables are able to function within future SPE communication networks.

Immunity from Interference for SPE in Noisy Environments

SPE can be deployed in noisy environments, where capacitive coupling and Common-Mode Choke (CMC) front-end circuits may not offer sufficient CMR to protect the link. Communication drop-outs or complete signal blockage may occur due to interference that is readily found in noisy environments. In this paper we consider the issue with some significant conclusions…
