please,i need details about a process that is controlled using plc.

See student project post for more details!

If you go to this site you will get a lot of information to help you with your assignment. Just remember it is copy righted, so don't plagarize. Use the info to develop your own paper, please.

PLCs have scads of uses. Scada uses, too!

I have used a plc for a doorbell in a manufacturing plant. Two doors at different locations in a plant office, both activating a single alarm, with indicator lights to show which one "rang", several reset buttons, and flashing sequences to show door status, alarm status, or time of day function status. Basically, you look bored, here's a SLC150, we need a doorbell, go have fun. By the way, the electrical contractor won't hook it up right anyway, but have fun.

I have seen wattmeters and plc's on coffee pots.

Plant soil moisture checker and automatic waterer, an on, and on, and on, and...

If you can think of something to do, you can probably come up with a way for a plc to do it, or assist in doing it.

If he hasn't turned his paper in by now, I expect he's not going to have to. This thread is 14 months old. Can't blame you for being helpful, tho.

I don't check dates, obviously.

Saw several people viewing it in the "Who's Online" page, thought it was one I missed.

Good opportunity to beat another dead horse further into the ground.....

Seperate posting section for students?

Seperate posting section for new injuneers?

Yeah, yeah, I know, back to my hole.....

There's a "Who's Online" page???

I have been (lived?) here since the opening of the new forum 2½ years ago, yet have NEVER stumbled across the "Who's Online" page...

And here I thought I knew every nook and cranny 'round here...

Thanks for helping me discover it, Casey!...

The faster way is to use the FORUM JUMP at the bottom of almost every page:

Of course, you also have to be a registered member to visit this page.

Casey:

Separate sections would never be used right. Phil has enough trouble moving real questions from "Practice Posting Here" to the LIVE! forum, as well as moving resumes posted in "PLC Employment - Offered" to the proper "PLC Employment - Wanted" section to want to hassle with anything more.

For me, I'd be happy if there was an "autolock" feature that Phil could enable so that any post older than, say, 3 months would not be allowed to be responded to.

Then, maybe, perhaps, THAT CERTAIN thread would finally DIE!!! (I think we all know which one I mean).
