As the subject says, can an Allen Bradley SLC 500 processor read/write to
a
PLC 5, 1771, rack and I/O modules? For my home brew experimentation
projects I like a SLC 500 rack and modules but sometimes I the variety
and
bargains I find in 1771 racks and specialty modules. Since most are
controled by BTW & BTR, thought perhaps a SLC 500 could use them. I
haven't
ever tried this so I'm not sure.

I don't think the 500 will talk to a PLC 5, but I don't know for
sure. But I am curious.. What kind of home brew experimentation
projects require PLCs? What are you measuring/controlling?

Well, it's maybe as much a toy and learning tool as anything else, but I
have some projects in mind that I want to try. I'm also wanting to teach my
son about PLC's and controls, I'm hoping to give him a head start by time
he's job hunting, he's 11 now so PLC 5's and SLC 500 might be out of date by
then but the concepts seem to apply.
One project is to use the analog I/O for analog circuit control, I've been
interested in making a multi-port battery charger using analog outputs to
control a switch mode power supply and read the battery charge voltage and
current with the analog inputs for both constant current and constant
voltage charging. The PLC seems like a nice platform for control and to be
able to see what is happening in the program.
Another project is to control my electric Brinkman smoker monitoring meat
temperature and internal temperature of the smoker. I plan to do ramp and
soak, I have ramp and soak temperature controls but they don't wait on the
setpoint to be reached, they just change the setpoint over time and if the
meat never gets to temperature I'd never know unless I watched it. I can
program the PLC for maximum internal smoker temperature until the meat
reaches the setpoint temperature and then set for 140 deg. F keep warm
temperature. Yes, I'm just playing but also enjoying some pulled pork BBQ
:-)
Yet another possible future project(s) include making a molding press for
rubber molding and plastic injection molding. I have a home machine shop
including a CNC lathe and CNC mill, I think it would be fun to make molds
using CAD CAM software and the CNC machines. Then using cylinders, valves,
and temperature control make rubber or plastic molded items(I work in a tire
plant and can get samples for cheap and consult with the chemists for the
properties I want). If I make something profitable, great, maybe a little
extra income, if not, no big deal, the education and experience would be
worth it.
In other words, I guess I'm just wanting a more deluxe Lego Mindstorm :-)
I'm underemployed so I come up with projects for a more interesting and fun
challenge (Crossword puzzles could save me a lot of money).
