That's thinking that's about 10 years out of date. Small industrial facilities are DEMANDING "integrators". If you're not an integrator, they're not interested in talking with you. Integrator is the new buzzword, and it would be good for the electrician's resume to make himself an integrator as well.

I've taken a few computer programming classes at college. Different animal, I know, but I'd really like to learn PLC programming. We've got an automation guy that's getting close to retirement. When he goes, a lot of facilities are gonna be screwed

I'd like to position myself as a viable alternative!

If you can read a ladder diagram (the way most electrical prints are made), you can program a PLC. I guarantee it, or my name isn't Orville Reddenbacher.

I can. What's a good place to start? Like maybe a free (that's the keyword) sample program I can download that'll let me screw around and program stuff for a simulated load.

I don't know much about what free or online training might be available. I'll have to let others chime in on that one. I sorta learned as I went, from the late 80's until now, so there wasn't much around when I started learning. Someone did link recently to an online simulator. I tried it real quick when they linked to it, but found it extremely frustrating, and I know what I'm doing.

You can buy a Micrologix PLC on eBay for cheap, and download a crippled version of RXLogix 500 from Allen Bradley for free (it's only crippled to the extent that it only works with Micrologix stuff). That's what I'd recommend you do as step #1. Build your own trainer with that stuff, and start messing around. Invest a couple hundred bucks in your future. Tuition is not cheap.

I still work on data highway stuff from time to time. It did have a certain advantage in that you didn't have the traffic issues you have with ethernet stuff like today, with all the VOIP and desktop PC's on "your" network.

Something that can help you is the learning pit plc stuff. I know it is a bit out of date but it has helped me alot.

If you are going to do mainly construction, you will not use it much.
Factory work, you would want to know all you can about it. The more you know about the trade, the better well rounded sparkey you will be.

This is right on the money. You will learn more about the basics, the setting up, how the thing is wired. And you won't have to worry about shutting anything down. I started by taking spare parts out of the store room at work and building my own trainer. Every night when things were slow(industrial maintenance) I spent the next 20 years using that base to troubleshoot and repair. All the big complex machines are just small parts working together. Learn these and you become very valuable.

Most of our shop floor machines have some kind of PLC in them. My only experience has been connecting them to our company network.
