Hi,

I don't understand your question. It seems you are asking what hardware to use but the question is to draw a state diagram. As yet there is no programming needed and no hardware specified. You are still in design phase.

cheers,

Hi,
If I understand your question correctly,  you are asking how to design a car park elevator using Siemens Step7. To do this, you need to draw a state diagram first. This will allow you to map out the different states of the elevator and how it should respond to certain inputs. You can then use this information to write the code in Step7 and control the hardware that you have chosen for your elevator.
Hope this helps!
