Elevator Program

i am making this elevator program in TIA portal
I have written a program but it is not complete yet

i created two arrays the first array is called state it has two bits 0,1 another has 6 elements , it detects the limit switch on the floor and writes 1 to that element of the array , and zero to one previous and one next floor ,

Next part is when i need to record all the calls from all the floors i need help

Can i use FIFO to record the requests
it is in the Function Library

hi;

i have a sugestion for you, i made some aplications on rotative tables i no its not the same but wat i do is:

i use shift rotate left or right its optional.
so you have one elevator just use a word and rotate a bit witch posicion is a floor, and you have perfect control to divide your program starting from there. just a view point i thinck its easier than using fifo(sry for the eng. i'm portuguese)

i created an array and everytime the elevator changes floor it writes 1 and sero to one floor low and one floor up

for example when the elevator is on ground floor and on 1st floor array looks like this

next step is to record the Requests from all the floors and make decision by comparing the Elevator current position and the request , also need to save the requests and execute

i cant get your question you can do it that way just build a cycle started by a request, that every time you get a request you send the elevator up or down and keep comparing current wiht request position.
like a (do while) cycle when current equal request you leave and stop

Can i compare two array

Ricardo Carmo · Jul 31, 2017

to compare arrays use scl, dont use ladder you will **** up trust me. but arrays are not for ladder are much better in a #c like language
i didnt had much time but here is a example
