PLC is a term that many years ago represented an Allen Bradley programmable controller, but has come to be interpreted as generic.

The reason for the shift is generally accepted to be this: Back when these products were young, they were known as Programmable Controllers, abbreviated as PC. Then, along came the IBM personal computer, also abbreviated PC. It didn't a genius to realize that when you said 'PC', the majority of people were going to assume you meant Personal Computer, not Programmable Controller, so Programmable Controller became Programmable Logic Controller, or PLC. Allen Bradley was, of course thrilled with this, much the same as Kimberly Clark was thrilled when facial tissues became known as 'Kleenex'.

SLC is a trade name for a product line from Allen Bradley and has managed to avoid becoming generic.

what exactly do you want to know about ladder logic? Just saying you want to learn about it is about like saying you want to learn to play guitar...there are several styles. Software is different from brand to brand, some instructions are present or absent. Also, there are different communication protocols involved.

G_khl,

if ur a begginer and want to learn programming PLCs...download this book.

Greetings gurleen,

back to your original question about the differences between PLC and SLC platforms ... this post contains some basic information that might be helpful ...

and welcome to the forum ...

thanx a lot for your help.
there are so many other things i want to know
a)how does the automation work really starts-i mean is it that first tags are made then the ladder logic and then the graphics are made and their animation is done??????????????????
if i am wrong then pls correct me and dont get angry on me cos i am trying hard but i still dont know much abt it.
b)i am training in a firm abt automation but i dnt have a desktop there-i have tried my hands at manuals but i think without doing anything practically i cant really get anything,pls tell me some good way of learning and practising.

pls kindly help and hanks for showing concern till now
thanks
