Sequence PLC Programming for Elevator PLC Program:

Step 1 : Elevator Up - Down ( 1 - B )
a. If Push Button B Outside = ON And the elevator was not in a position B Then elevator Move to B.
b. If Push Button B Inside = ON And the elevator was not in a position B Then elevator Move to B.
c. If Push Button 1 Outside = ON And the elevator was not in a position 1 Then elevator Move to 1.
d. If Push Button 1 Inside = ON And the elevator was not in a position 1 Then elevator Move to 1.


Step 2 : Door Open - Close
a. IF Limit Switch Position B = ON (Pulse / diff.Up) Or Limit Switch Position 1 = ON (Pulse / diff.Up) then Door Open.
b. IF Limit Switch Door Open = ON Or Safety Sensor = ON then Door Close.
c. Continuously to Step 1
