Functional Description
When the user pushes the left paddle push button then air will flow to the left paddle cylinder and it will rotate. When the right paddle push button is pushed air flows to the right paddle cylinder and it will rotate. When the shooter push button is pushed air will flow to the shooter cylinder which will extend pushing the ball into the gaming area. When the ball hits any scoring limit switches the light will accumulate in binary. When the ball lands in bonus areas it will start a time delay and then air will flow to the cylinder that will push the ball out and back into the gaming area. When the paddles are pushed sounds will play. When the scoring LS are hit sounds will be played.
All of the inputs are wired into a PLC and all of the outputs are as well and to use the output and inputs we will write a program that serves our functions properly. The way the PLC works is it constantly checks all of the inputs for a binary one or zero. If it sees a change in one of the inputs it checks the user program and sends electricity to the corresponding out put. For example if the left paddle push button is pressed the PLC will receive a binary one with that voltage and then check the user program then it will allow voltage to flow the left paddle output.
