Good day i need some help with programming a S7-300 PLC with the step 7 V5.5. Below is the description of the project. Project: Elevator Control using S7-300 PLC and a Sinamic G110 You are required to implement a engineering solution to the problem presented below. An elevator is to be used to move goods from one floor to another. Start and stop pushbuttons are allocated on each floor. Stop pushbutton must only be used in emergency situations. There are two sensors allocated on each floor (total of four). One is used to slow the elevator down as it gets close to its final destination while the other is used to stop it. The elevator can only be started from the floor it currently occupies. Stop button can be operated from any floor. (Note: the direction motor must be reversed once it has reached its destination floor and the start button activated.)The VSD has to be interfaced to the PLC and all the control must come via the PLC. Implement the following: Start N/O pushbutton (with jammed switch protection), Stop N/C pushbutton, It would help a lot if you could provide me with the necessary coding. Thank you very much ------------------------------------------------------------------------------------------ |

Good day thank you for the reply. I'm using a input/output interface. so if i change the output from 10V to -10V will the direction of the VSD change? Thank you |
