I finally found the download link.

The file "PLCBUS Technical Informations.pdf" has absolutely no technical
information. It is all marketing fluff with a pitch for investors.

Some of the things included in the PDF are quite similar to the slides in
this presentation...


so it may be that they have copied UPB. There just isn't sufficient
technical detail to decide.

The PDF does indicate they plan to enter the US market while in another
place on their web site they claim millions of existing installations in the
US and Europe.

At the end of the document (p29) is this...
As of June 2005 SSE Ltd. has filed two patents covering the
basic methods and implementation of the PLCBUS technology.
If it is UPB or if it is licensed from a company in Holland (ATS Ltd), they
certainly could not patent it.

"PLCBUS Specification" is an .rar file. It has a corrupt header and WinRAR
cannot open it.

I won't waste anymore time on this.
