Are there any alternative technologies that rival the PLC?

Yes, Relays & Contactors !!!!!!!

PC Control !!!

Pneumatic Control !!!

Hydraulic Control !!!

Mechanical Control !!!

Seriously though PIC's can rival PLC's but they require additional electronic assembly, and by the time your finished they resemble a PLC.

Hello Everyone !

How about PAC ? (Programmable Automatic Controller)

Looks like the PAC can replace the PLC....

Did you hear anything about that ? See the link below:

Let me know what do you think about it ...

Just kidding... I was trying to find out if PAC is a "revolutionary" thing or just a fancy name for PLC...

I've heard that a H.U.M.A.N. can be a very powerful tool. They're a little slow, but you can't match the processing power.

Did we send PLCs to the moon to dig up rocks and hit golf balls? Nope. We're sending them to Mars instead.

Absolutely. There's the pivoting fluke, the kedge, the tripoint, the mushroom, and the plow.

Actually, Ken, on the off chance that our question comes from an HNC student, I think that should be "plough".

"powerful laptop computer"
The last piece I read said the processor was 20Mhz. Of course, I think it also said 128K RAM, not 128Mb.

I suppose if you don't run Windows on it, 20Mhz is plenty.

It's fun to read the tech specs on space craft because NASA's approval process keeps them so many years behind the curve. With good reason, of course. I like to wonder what we could do if we could just take the best of the best, right now, and fling it into space.
