'UK Elektor PLC Emulation Article using a PIC.'

There was an article about using a PIC for PLC Emulation by Walter Ditch
in the UK Elektor Magazine in 94/95?

It uses a PIC16C54 or 55 programmed with ladder logic.
This is a system of programming more suited to Electricians and
Electrical Engineers than Computer programmers.

The files and examples assemble with the old MPALC, and it's really
simply a system of Macros in a shell.

I just had an old customer send me the files which are clearly marked
'Public Domain'.
He would like the thing to work under MPASM and the later micros, in
particular the 84.

I did a long search of the Web for the Author name/article/etc.,
thinking there may well be an update, but found nothing. Lots of Elektor
mags in European countries, but not the article I was looking for.

To save re-inventing this wheel, does any one know if there is an
upgrade, failing that, it there someone interested enough with a need,
that may like to have a look at it with a view to spending a couple of
hours converting/upgrading/testing it?

Files can be privately E-mailed and aren't that big. 133K zipped
including MPALC and MPSIM.

Hi PLC Folks,

its so funny that I took those few hours few days ago and converted
the PLC.H files that really is Public Domain to PIC16C84 so it is
done already!

ftp://ftp.sistudio.com/pub/mchip/source/plc.zip

contains the pic16C84 port of the original PLC.H file.

Hey what took you so long Antti?
I needed them before breakfast. :)
You recently said on this list that there was only 25 hours in a day.
I found that's true only for the first six days of the week.
The other three have 26.

Thanks, I know a man in Perth that will appreciate your efforts and the
feedback very much.
