Ladder Logic
Ladder Logic
(OP)
Hello,
I learned a bit of PLC during my apprenticeship about 10 years ago writing in instruction format in dos on old bosch plcs. Now i'm required to work on mistubishi q-series and fx series on windows and in ladder logic.
I'm fine with the troubleshooting side of it, but editing and re-writing in ladder is stumping me a bit.
I'm spending a good hour a day now working on it, but has anyone got any tips on how to improve my ladder techniques? Any books, websites etc etc?
Thanks in advance.

RE: Ladder Logic
let me explain to you maybe this is can help you.
Ladder prog it's symbol like electric picture there is switch NO or NC than output at ladder is coil or timer or special fuction.
the program PLC had you studied last time it's call LIST program, at the plc software mitsubishi like GX Developer you can change to view the program at model LADDER or LIST.
if you want to know what is the meaning fuction at the ladder prog you can see help menu in the soft, there expalined everything.
RE: Ladder Logic
I fully understand ladder and how it works. I can fault find someone elses software with relative ease, but when I come to edit a step sequence or something, I struggle.
How can I improve/practice my editing? The easy answer is to just spend time on it, but I havent got that luxury in work at the moment. Is there anything I could do at home? Or is it a pure case of practice makes perfect?
Thanks.
RE: Ladder Logic
maybe you can use mitsubishi FX Trainer to learn makes program Ladder without PLC.
At the software you can makes a program then you can simulated the program.
Try use this link to download the progam :

My fav is AutomationDirect. Call the expense an "investment in [your] education."
For all practical purposes, ladder logic is generic. Each manufacturer has generally the same functions, they just get implemented in programming a little differently. If you learn deeply the basic theory, it can be applied to any PLC.
And yes, practice makes perfect.

RE: Ladder Logic
I highly suggest using the help files that come with that and then it was suggested to me that if I had questions on how it worked/reacted that wasn't in the help files clearly to just program an example of that to see how it was handled.
Worked out nicely for me and I managed to get through a (7) furnace/(7) heater system running on generator mode with certain requirements!
Best of luck to you and if I can find the help files I had used as well and a good PLC book I will add it hopefully this week. I saved all of my files somewhere!
