The Power over EtherCAT enhancement, adopted at the recent fall meeting of the ETG (EtherCAT Technology Group) Technical Committees, which took place near Frankfurt, Germany, makes use of the IEEE802.3af Power over Ethernet (PoE) functionality and can be implemented with commercially available chips. It is particularly suitable for encoders or linear position sensors, which now can be connected to EtherCAT using a single, standard Ethernet cable. Stub lines and star topology together with line, tree and redundant ring have always been part of the EtherCAT topology variety. This is now enhanced with the possibility to build devices with just one connector each that are powered over the data line. For this, the Power over Ethernet standard IEEE802.3af is used, which supports up to 13 Watts per device. For EtherCAT slave devices, the ETG specifies mode A of the standard, which only needs 4 wires: standard Industrial Ethernet connectors such as the 4-pin M12 can still be used. Devices powered by a separate line can be connected to Power over EtherCAT breakouts. It is also possible to enhance the spec towards the future high power IEEE802.3at standard (PoE Plus or High Power PoE), says ETG.
