Programmable logic controllers

[ecat]

SattBus appears to be a highly specialised protocol, I doubt anything other than these controllers understand it.

The other protocol supported be these controllers is COMLI which again appears proprietry though there is little information. It is possible to communicate with a modem using CHA and TXT, the latter allows for the transmision of text strings - this is good, the former may allow you to read incoming characters - little information available so you would need to try it to see if the controller can keep up with an incoming message.

If the controller you have is an OP45 then that is a very nice keyboard and display, it would be a shame to waste it. My 1st thought was trying to interface with a set of digital calipers :) but I don't think the controler is fast enough :(

Certainly you can display messages on the LCD screen and switch digital signals and analogue values from any connected I/O modules in response to key presses... Perhaps you should stay the trip to the skip (1) for a couple of days and see if any use comes to mind.

(1) It is of course frowned upon to throw any sort of tech. item in your general rubbish bin. They call it recycling but after much though I've realised this green ideal is nothing but a smoke screen to hide the real reason: You throw your old pocket calculator in the rubbish bin and a week or so later it ends up at a landfill site. See where I'm going with this? Landfill sites are always heavilly populated by seagulls, only now, thanks to your pocket calculator, they are seagulls with the ability to do trigonometry! Ha! What next? An old PC set-up and they're on the internet, an old mobile phone and they are making annoying phone calls, all powered by half dead batteries. Seagulls are frightening enough, but now armed with D.I.Y death-ray plans from the 'net and advanced communication devices so they may plan their attack I fear the days of mankind would be numbered! It may be a smoke screen but recycle I tell you, recycle now or the dinosaurs will once again be masters of the Earth.

well, its a theory, lol

Hi Guys, thanks for all of the input.

Programming.....Humm last time i atempted any real programming was with BBC basic, and i don't think i going there again
So last chance before i "recycle" them is does any one want em cos i have kept them long enough, the only thing i have thought to do with them is to remove the edge connectors and aluminium backing plates, the rest is .......for the seagulls, they can pick through the remains for as long as they wish, perhapsthe components and there dasterly plans will keep them away from the beach

there's a new member - "usedplcs" who is involved with a company that does, well, used plcs... he may be able to give you a view of whether there is any refurbish value as an alternate to 'recycling'
