Hmmmm... it's that smell of Google groups and gmail again !

To Mr praptr....

If one day you learn how to string words to gether so as to make a coherent
sentence and choose to use this skill to explain yourself in more detail you
might find it elicits a more helpful response.

Do you by any chance mean programmable logic controllers btw ? I'm sure Google
can help you.

Succinct and to the point.

Assuming you're talking about Programmable Logic Controllers
(industrial computers with a built-in sequential programming language
like ladder logic and inputs and outputs which can be directly wired to
machines), you're looking at the wrong newsgroup. Try sci.engr.control
for more information.

Any use of PLCs assumes you know about basic industrial electrics, and
how to safely wire and power up things to make them work. If you
don't, learn that first. Be safe.

Just off the top, if you're starting from scratch, you should just get
one and play with it. Many manufacturers of small PLCs make intro
packages which will allow you to set up a working PLC with a PC-based
programming environment for a couple hundred dollars.
Automationdirect.com, Omron, and other manufacturers make these kits.

The manufacturers provide massive amounts of data on their websites.
Before you buy, get a couple of catalogs and read them carefully.

PLCs are easy, fairly straightforward ways to get automation projects
working. Just jump in, the water's fine. And if you're starting out
with a small application (a few sensors, a few relay outputs, nothing
millisecond time-critical), you can just throw your learning kit into
the machine and, in effect, get a free self-taught education.

Good luck
Chris
