Well, they are different animals really, a PLC is ready to go, with just In's and Out's ready, easy programming interface, and the newer ones are quite quick. Good for data logging, easlily add a HMI. A microcontroller is similar to the in's and out's, but a number of external compoents are needed, osc, reset circuit etc. Microcontrollers are cheaper, a lot quicker, but programming is a lot more time consuming. Depends on the application

Hiya-

I have an open source project page that converts ladder logic
programs to PIC assembly source code. It uses an open source
ladder compiler available on sourceforge.net called opencontroller
the PERL interpreter (available standard on unix, linux machienes
or download free for windows machines), my little translator
script that takes the output of the ladder compiler and translates
to PIC assembly code, and finally the microchip assembler to
change it to binary code.

details at:

http://getok.net

The code is extensible (can be used with many of the 10F, 12F,
and 16F series of processors), does not need any additional
hardware other than a battery.

So, for a couple of bucks one can have a programmable logic
controller.

This code is somewhere between alpha and beta stages and I'm looking
for folks to help test this. The basic commands all seem to work,
however, systematic testing (other than module testing) has not
been done.

Since I'm giving the code away, I don't think that this should
be classified as "advertising". I hope the group agrees.

Cheers,

Rich S.
