Hey, did you think that this is another 'Programmable logic controller'? If you did, then you are totally lost as this is a new entrant from the house of Logitech, it is called the 'High speed power line communication Ethernet adapter'.

The company speaks very highly of this LPL-TX adaptor and boasts that it is UPA compatible too, so, that makes it one of the highest rated data transferring (200MBps) PLCs on the planet!
