Hi Folks:
Thanks to some brilliant timing from some others in the list, I thought I would share with you all something I have been working on in the background.
I am trying to (also) develop an Allen Bradley PLC5 emulator under Linux (and contribute it to the Project in general). I currently don't have much for code, but I do have a written out (partial) spec that I was going to use as a guide.
This spec should allow for a decent engine to get built, one that would be highly extensible and/or customizable. To that end, I would like some comments on it. Please keep the flames to yourself though! I know there are Modicon
folks in here as well as Seimens/GE/Mitsubishi/whatever. I am not trying to force something on to you folks, I am just going with something I know - the PLC-5. From what I remember, this project was *supposed* to be able to have a pluggable logic engine interface so it *could* emulate a PLC5, a Modicon, or whatever.
On a side note, I thought seriously about building a (software based) Allen Bradley PLC-5 workalike system under Linux (simular to the SoftLogix product currently marketed by AB). By workalike, I mean something that I could talk to
it via RSLogix5/AI/6200 and make it work. Probably emulating a PLC5/80E or something like that (to guarentee that even 6200 would be able to talk to it). I am not sure that this is a good idea as it would be obviously stepping on way
too many toes at AB. Unless some management level person from AB can give me written assurance that this would be welcomed, I don't think I am going to try. The way I see it, this wouldn't be too hard to do though.
Anyhow, please look over my proposal. It is kinda rough in the writing but should be able to give a decent idea of what I am aiming at. Please note that there are a few extensions above and beyond what AB has with the PLC5, notably
an Inverted Output, a One-shot Transition Contact, and a dedicated one-shot register group.
Thanks folks!
