Connectors and Cables Tag 4 – Freitag 15 November 2024 Henkel points out But why is it necessary? “Well as things stand today the profiles cannot be freely combined with each other and the different IEC 63171 mating faces are not compatible with each other either This means that a system specification for the respective industry is required so that the user has a guide when selecting devices and components In the process industry this has already been achieved well with Ethernet-APL but is still lacking for industrial automation ” The building automation sector may have a somewhat easier time with this aspect as according to Henkel it is already foreseeable that plugs and sockets will play a subordinate role there “Pull the SPE cable through the empty conduit lay two wires in the connection compartment of the flushmounted box – done ” Conclusion The vision that SPE is a new milestone for Ethernetbased communication still exists The advantages that it offers compared to other technologies apply to various fields of application cp Harting Hall A2 Booth 103 Phoenix Contact Hall B3 Booth 103 Rosenberger Hall B2 Booth 356 Wago Hall A2 Booth 318 Weidmüller Hall A2 Booth 319 IP67 version of SPE-Ethernet switch that the field of application for Single Pair Ethernet extends beyond industrial automation “In fact the market is much much bigger In principle all industries that have an OT are target markets for Single Pair Ethernet because the technology solves many challenges ” Henkel points out “Whether it’s space weight resource requirements connection effort or CO 2 footprint – SPE is the answer to many questions about communication of the future If you add external requirements or constraints – such as the Cyber Resilience Act skills shortages and sustainability – to the future view then SPE shows its great potential for finding and providing solutions ” Even IT is receptive to SPE says Henkel because miniaturization and reduced installation time are also very welcome here Is the technology ready for the market? Since its market launch in 2015 in a closed system car a lot has happened in the development of Single Pair Ethernet “Looking at it objectively in terms of OT the technology is now at Technology Readiness Level TRL 7 to 8 – and is therefore in the market launch phase ” explains the Wago expert “However the technology is not yet fully developed in terms of what is technically feasible – if one can expect it to be completed at all ” he continues The technological potential has therefore still not been fully exploited and improvements are constantly being added These include the 100Base-T1L protocol with 100 Mbit s over 500 meters which removes the critical length limitation compared to 100Base-T1 100 Mbit s over 40 meters 10Base-T1M for example is also in the starting blocks which promises further potential benefits compared to 10Base-T1S such as more participants and an extension of the maximum length “Multiprofile support extended diagnostics for connection quality and many other features are what drive developers in the SPE area and the end of the technological road has probably not yet been reached with Power over Data Line either ” It is precisely because SPE is evolving in various ways that Ethernet technology is future proof However there are still challenges and outstanding questions from customers “SPE is not just a communication technology but essentially also a system technology As such it only shows its capabilities and benefits in the system network and not so much in the component The technology is ready for the market with TRL 7 to 8 but the system specifications are not yet sufficiently specified in all areas ” explains Henkel And further “This is where user organizations such as the PNO or the ODVA come in among other things to define cabling guidelines and the IEEE 802 3 profiles so that the ‘device zoo’ can also develop its performance in the system network ”
