looking to lean more about plc
(OP)
I have taken a few classes on PLC but still a little nervous to plug the labtop a work. I dont think i could find what i was looking for. and no one at work want to show me any thing. Does any one know any good books or any good cheep classes.

If you are worried about connecting to a live control system then its probably best not to! However if you don't change anything - ie. just checking values or saving a copy of the program for offline reading this shouldn't cause any issues.
It might be worth getting any spare PLC you might have connected up on the desk to "play" with and get a feel for things.

If this is a maintenance position then do the following:
If your that afraid, put the processor in local run mode where their is no chance that you could screw something up. Then get online with the processor. Best place to see what is happening with the program is to have a device layout and see where these devices are acted on in the program. Once you know what the program is doing when its acting normally then you would be in a better position to troubleshoot it when it breaks. Biggest problem I have with maintenance people is the only time they look at the program is when the machine is not operating correctly. Then they think something is wrong with the program and its really just some device has gone bad.
If this is a programming position then the company should have standard code or past programs to look at locally on your hard drive. Once you look at these then you can ask some informed questions.

www.plc.net has a great basic primer class with a good low cost student manual for starters. Try Ebay for a small PLC then check the local distributor for a copy of the demo software.
Also try www.mrplc.com
Hope that helps.

They would do very well with small lab tasks. The price is astoundingly good!
They run ladder logic or function blocks pick whatever you want.
The software is free and you can download it, and run it now, and do simulations. It is nowhere near as powerful as most PLCs but it has all the major aspects. Do a project with one and you will have a solid idea of PLC concepts.
