And barely any of this relates to PLC's but anyway I'll throw you a bone. 

Look up the 'mrmattandmrchay' youtube channel, they have produced a number of videos relating to an older relay operated lift.

That will probably answer all your questions.

In my opinion the control system for an elevator spanning 50 floors is a task for an OEM of elevators and does not qualify as a DIY project.

Given you're dealing with Human Life and Safety may I suggest - https://ieeexpo.in.messefrankfurt.com/mumbai/en/facts-figures/elevator-resources-guide/codes-standards-for-lifts-escalators-india.html

And if you want to be bleeding edge in India - also check the American Standards -- https://blog.ansi.org/2016/11/asme-a171-2016-safety-code-elevators-escalators/#gref
