Hi PeterH,
thank you for your answer.
So about my lift:
- 4 floors
- 7 magnetics sensors (4 to stop the lift when arrived to the floor and 3 between to slow it before the stop)
- 4 contacts switches to verify if the doors are closed
- 4 contact switches to verify that the Lock is activated
- 10 buttons to call the lift (1 at level 1 (you can just go up) + 1 at level 4 (you can just go down) + 2 buttons at level 2 + 2 button at level 3 + 4 button inside the hoist
I don't understand what you mean with "Also assume that your short term memory is useless".
I would like to store if someone call the lift when the lift is already in use.
Thank you
