Harting Americas has launched their Single Pair Ethernet technologies.SPE communicates across the common industrial Ethernet protocols available today but instead of using 4 or 8 total wires, it accomplishes communication across just two wires, a single twisted pair. It uses Power over Data Line technology to bring communication to the device along with the voltage and amperage needed to power the device. This is hugely beneficial for three reasons:. First, space and number of connections are reduced on the device. Second, the need for an external power supply is eliminated. Finally, devices on the plant floor that have traditionally communicated over Fieldbus protocols can now join the same IP-based network that the rest of the devices on the network are using. This enables peer-to-peer communication, open-loop feedback of all devices, and smart functionality all the way from the main control room down to the individual device.
