ROTFL

If I write: "people who can't read", does that mean that "all people can't
read " ? <joke intended>.

>You do not know what you are talking about

Apparently I wasn't clear enough. One part I wrote that wasn't
clear/read/understood/responded to was: " This applies to Ocelot, security
panels and most  "distributed control" devices" [used in home automation in
North America].

Are you are claiming to be able to reprogram an Elk MM443 or Slinke on the
fly? Good luck!

I didn't discuss European EIB, did I? The original poster is in North
America, not Europe, and the vast majority of all posts and discussion in
this newsgroup concern  North American homes with 110v systems, subject to NA
building and other codes. Clipsal pertains because a major US distributor has
announced that they will distributing Clipsal in NA this year. European
Installation Bus (EIB) is not in common use anywhere in North America as best
I know. This has nothing to do with anyone being stupid. It is a matter of
different markets, prevalent codes and other regulatory requirements, and
household line voltage (220 v 110).

>If you have an argument atleast make sure you are correct in you
>statments

What I wrote is correct, but I can see how it could be misunderstood. I did
not say that all ladder logic or other devices had to be stopped. I
specifically stated that (eg) Clipsal could be updated on the fly. That is
not the case with many HA devices in common use in NA that are the subject of
discussion in comp.home.automation. European Installation Bus (EIB)is not
used in US and Canada.
