Has anybody heard about PLCBUS? Is it the 220-240V version of the UPB?

Re: PLCBUS


They don't provide much technical data on their web page...

     http://www.plcbus.com.cn /

But there is enough to see that it is not UPB. They say it's low frequency
spread spectrum and can send 10 commands per second. It is two-way and
supports 64000 addresses. Their RF remote can send their commands and can
also send X-10 commands. They claim there's no need for filters (color me
dubious) nor couplers and say it can coexist with other PLC systems. It's
worthy of investigation.

Re: PLCBUS


Dave,

I have some technical material regarding this PLCBUS, I can email it to you
if you want to investigate any further. I also have some informations
downloaded from PCS (UPB inventor).
From what I see, both informations from PLCBUS and PCS are "almost the
same". I know that PCS is the first to use this similar technology without
any doubt.
The reason I raise this issue, because I want to incorporate PLCBUS devices
as they are 220V products and has the advantages of UPB. But if it is not
compatible with my HAI OmniPro, then it is not possible to do so.
By the way, does anyone know how HAI UPB serial connection work? Is it
emitting an ascii text ouput to control UPB device via their PIM? Or is it
binary command? Just cross my mind that I might be able to make an interface
between the PLCBUS transmitter and HAI.
Thanks for your response.
Rgds,
Jo

Re: PLCBUS


Jo,

UPB discharges a capacitor to generate a (noise) pulse. It would be a bit of
a stretch to call that spread spectrum. If it were on a 50Hz system it would
be capable of 200 bits per second which is 200/8 or 25 bytes per second. UPB
uses a variable command length which can be 7-25 bytes long. Even with the
shortest command, that's 25/7 or just under 6 commands per second (with the
longest command it becomes 1 command per second) as opposed to PLCBUS which
says they can send 10 commands per second.

The English version of their web site is difficult reading because the
English is awkward so I suppose it might be UPB based. They indicate they
licensed the technology from a US software company called Magma. Whether
that's related to PCS, I don't know.

Your best approach is to send email to info@s10.cn asking the questions you
have directly.

done that ten times minimum.. no response  still on holidays "labour
day" :-)

will want to order but not encourging response   i.e. no response to
mails /leaving queries on the site /calling 800 number

if any of you get lucky  let me know as well


Re: PLCBUS


That's not encouraging since China's Labor's Day holidays were May 1-7.

A little more sleuthing on their various web pages turned up this link on
the origins of PLC-BUS. It appears to have nothing to do with UPB.

     http://www.x10bus.com/customercare/news-20.htm

I really doubt that it even exists outside the imagination of whoever
created the press releases.

Re: PLCBUS


Dave,

this company do exist, I have bought X-10 switches from them. I also have
send emails asking about their similarity with UPB, but as you might have
expected, no good answers regarding technical questions.

Saying that this technology has nothing to do with UPB, I think it is too
premature. If you have downloaded UPB_Overview.pdf from UPB and "PLCBUS
Technical Informations.pdf", I believe you would say there is something
between the two (At least their presentation format and general
informations). Go to "UPB Communications Summary" on page 6 of the first pdf
file and compare it with "3. Product Definition Product Features" on page 18
in the second pdf file. You would be surprise on how similar the two.

My suspicion is that UPB licences the tecnology to this company with the
agreement that S-10 can use a different software protocol and market them
with different name. In terms of hardware signalling, I guess both of them
are at least almost the same.

Just my two cents.

Best Regards,
Jo

Re: PLCBUS


I don't doubt the company exists but I seriously doubt the PLC-BUS product
line exists.

Do you have a URL for "PLCBUS Technical Informations.pdf"?

The press release makes it clear that they licensed the technology from a
company in Holland rather than from PCS.

Re: PLCBUS


I could not get into their website just now, but it is in the donwload link
on www.plcbus.com.cn.

If you have a yahoo mail or any other email that have anti spam, maybe I
could send both pdf files to you.

BTW, they do have their PLCBUS product lines, I've got their price list.
Just not sure should buy or not for compatibility reason with OmniPro II.
They suggest using their X-10 to PLCBUS transceiver which I do not interest
as this scheme still using X-10.

Re: PLCBUS


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...

     http://www.ieee-denver.org/comsoc/presentations/UPB.pdf

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...
<quote>
As of June 2005 SSE Ltd. has filed two patents covering the
basic methods and implementation of the PLCBUS technology.
</quote>
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.

Re: PLCBUS


Hi...

I using PLC-Bus for a couple of months now in my house and it works
exactly as they specified. Fast, reliable and compatible with X-10.
Don't want use any other system anymore...

PLC-Bus is already excisting for a couple of years... in 2002 invented
by ATS Ltd. in Amsterdam, Netherlands.... UPB is just 2 years old and
PLC-Bus is launched by ATS Ltd. in 2002 after several years of
development.... probarly is UPB based on PLC-Bus as they have a lot of
same technical specifications...

Reason for me to use PLC-Bus is because a lot of big companies like
Philips, Microsoft, IBM, KPN, Nokia, Motorola, HP, DELL, IBM, Siemens
and Intel have a agreement with PLC-bus and plans to use it in there
consumer electronics. Philips is coming soon with new lighting on the
market... called SMART LIGHTING and is based on this PLC-bus... PLC-Bus
is already tested for several years and now ready to be launched as the
new industrial standard for home automation & networking...

Personal I don't trust UPB... they call them self the leader for remote
lighting control.... yeh right... X-10 is still the most used protocol
for Home Automation worldwide... okay that is there marketing
strategy... compare your systems with a old technology of 30 years
ago.... but if I read there website and the technical documents I get
the all time different specifications.... 62.500 or 64.000
addresses.... 480 or 240 bits.... 4 or 6 signals per second... 40 or
100 times faster then X10 ( yeh right, I need to wait 50 seconds for my
light goes on? ).... compare UPB with the modern systems from the last
2 years like PLC-Bus, Z-Wave, S10, X-10 II... and you will see a lot in
common.... so UPB is just the next clone of X-10 only with the
arrogancy that they have THE system..... only the advantage other
systems that they are compatible with X-10.... UPB not....

my 2 cents...

Jack, what home controller do you use?
Can you give me the ATS homepage, I'd like to learn further about their
invention.

Could you also give the URL for Philips Smart Lighting that uses PLCBUS
techonology? I need to get further information and google did not seem to
return usefull information regarding this.

Re: PLCBUS


My friends,

The home automation registered standards in Europe are:

Konnex and LonWorks!

All the other systems around are proprietary ones or are not industry
standards recognized as such.

I was looking for Jack's response actually. Because he seems to have all
the informations regarding the PLCBUS.

But now I got your message that PLCBUS is not (yet) the standard for
home automation in Europe.

The details of the UPB serial protocol are included in their PDF "UPB
Powerline Interface Module (PIM) Description" available from their web site.
