Ne wto PLC
(OP)
Hi,
I am an uneployed electrical engineer new to PLCs. I have put in about 40hrs into classes, simaulator, books and I think I am getting a hang of things. Now please a couple of questions:
1. considering the number of hours of learning PLC, it takes me an average of 2hrs to solve pratice simualtion exercise in Mitsubishi training software. Is this to much time?
2. Is it sufficient to take classes, self study and the rest to get a job? I see that companies want experience. Can classes equal experience? I am asking this questions because I dont want to pump in money and at the end realise that what I have done is not sufficient.

RE: Ne wto PLC
Having classes in ladder logic is a start, but everyone wants "experience." I'd suggest continuing your independent study for a short time more. Obtain some cheapo PLC & HMI hardware, create a dummy project with sufficient complexity, and do all the hardware integration and programming. Document the entire affair with pictures, printouts, design drawings, etc., and use that as a portfolio to show off when you interview. PLC work is not rocket science, but not everyone can do it. But those things are pervasive in the industry landscape. It is easy to see who has experience doing it and who doesn't. You need to be able to show you have the foundational skills necessary to hit the ground running on a project.
At least, that is what would impress me if I was interviewing someone like yourself.
Knowing ladder logic or other programming is only a start. Experience will give you:
- good programming style for subsequent ease-of-maintenance
- knowledge of how to deal with signal timing issues
- knowledge of various types of signal & hardware integration
- foundations of good HMI design and how those things work, and how to make them useful for operators on the shop floor
- good wiring practices
- specific hardware and software functionality knowledge

RE: Ne wto PLC
Many people think that PLCs are just some simple ladder logic, which can be true, but the bulk of todays needs are system integration. Networking drives, OPC connectivity, HMI interfacing, etc.
RE: Ne wto PLC
Probably not. It takes time to do any task. But you've done it, you did it on your own (not in class room situation with one worker and one or more sloth drones) and the next time you need to do similar tasks it will take less time because you're familiar with the syntax and the operations involved in making edits and changes.
Keep it up.
I'll endorse the tygerdawg's suggestion to check out the forum at PLCtalk.net - just reading and understanding others' problems and the solution suggested can be an education. It'll also show how much of the problem solving is integration (like automatic2 mentions), not just ladder logic programming.
