IEC 61918
SPE cabling and installation
The new edition of the installation standard IEC 61918:2018/AMD1:2022 Amendment 1 was published in March. The standard now also includes important key points on cabling structures based on Single Pair Ethernet (SPE).
The new amendment to IEC 61918 addresses the new 1-pair cabling structures for SPE and the associated PoDL (Power over Data Line) remote power supply. This closes the gap between classic IT infrastructure and industry, IoT/IIoT. SPE enables the consistent use of TCP/IP-based automation protocols, even over long distances.
Higher data rates, more power transmission and greater ranges than with classic fieldbuses are paving the way for IIoT and Industry 4.0. The new version of IEC 61918 now clearly and unambiguously describes in standard form how and with which components a sensor-to-cloud data infrastructure must look in industrial applications.
