1. Ladder program 1

THIS LADDER PROGRAM IS MADE IN RSLOGIX MICRO. SO, THE ADDRESSING IS LITTLE DIFFERENT, BUT THE PROGRAM WILL RUN EXACTLY YOU WANT IN RSLOGIX PRO. List of Inputs and Outputs: 1: 0/0 = PB_1 (Input) 1: 0/1 - PB_2 (Input) 1: 0/2 = RESET BUTTON (Input) 0: 0/0 - CORRECT SEQUENCE LIGHT (Output) 0: 0/1 = ERROR SEQUENCE LIGHT (Output) WORKING: 1. When PB1 i.e., I: 0/0 (NO) is toggled it becomes NC.(in rung 000) 2. And, when PB_2 i.e., I: 0/1 (NO) is toggled it also becomes NC. Thus Correct sequence light starts glowing. (in rung 000) 3. If PB_2(I: 0/1) is toggled before PB_1(I: 0/0) then in rung 001, PB_2 becomes NC and error light glows. 4. Once the Error light(0: 0/l) starts glowing, (then in the rung 000), error light NC button becomes NO which prevents the glowing of correct sequence light even if PB1 is pressed next. 5. Then when the Reset button(I: 0/2) is toggled, it becomes NO which breaks the conduction in rung 0001, which stops the error light.
