4. Write a program that will execute the following steps. When in steps b) or d), output C will be

true. Output X will be true when in step c). a) Start in an idle state. If input G becomes true go to b) b) Wait until P becomes true before going to step c). c) Wait for 3 seconds then go to step d). d) Wait for P to become false, and then go to step b).

a) Start in an idle state. If input G becomes true go to b) b) Wait until P becomes true before going to step c). If input S becomes true then go to step a). c) Wait for 3 seconds then go to step d). d) Wait for P to become false, and then go to step b).

1. A PLC is to control an amusement park water ride. The ride will fill a tank of water and splash a tour group. 10 seconds later a water jet will be ejected at another point. Develop ladder logic for the process that follows the steps listed below.
