Where is your work so far?

If you use the search feature here rather than just posting a homework question, you will discover many threads about elevator projects. Have at it.

What does it do, that you want it to do? (what works so far?)
What does it do, that you don't want it to do? (bugs?)
What does it not do, that you do want it to do?

whenever I press any pushbutton I want motor to run in forward or reverse direction (MF or Mr) unless proxy sensor of that floor is on.
but in my program motor is not getting latched when I press any pb.
I am new to this. I have basic info of plc and ladder programming. therefore m trying to solve such questions to increase my logic solving capability.

Sorry, but I can't read your code. Zooming only makes it more blurry.

Link to example program in the "Downloads" section>Allen Bradley directory.

Just print your program with a .pdf file writer like CutePDF and attach it to a post. That way we can see it without the RSLogix software.
