I (college student), and my group inherited an elevator project that is supposed to operate between 3 floors. We stripped it down and have reassembled it. We have wired a 24vdc motor so that it can be ran forward and reverse. We also have wired a couple pots in series with the motor to control and adjust the speed both up and down. We have also counterbalanced the elevator, and hard wired a solenoid to disengage the brake while the elevator is moving. Limit switches are hard wired into the plc from each floor. Up to this point the project works good,as we can adjust to the proper speed and it is mechanically sound.
Now we are at the programing stage, and have tried with limited success to get the elevator to correctly respond to the call buttons on each floor. The paramaters, as far as the function of the elevator, are: it needs to be able to respond in an efficient manner to multiple call button inputs and logically deliver passengers to their destinations
I have programmed a couple of different ways and am not sure if I am going about it in the right way.
I am somewhat familiar with subroutines and think that this may be the best way to get the elevator to proceed to a specific floor in a specific manner. However if a fifo stack could be adjusted after data has been entered, this might work as well. I have also considered using AND, OR, or other instructions.
I do not need or want anybody to email a sample elevator program, but if any body can give me a few suggestions, I would appreciate it, thanks.
