Enter the ladder logic for the cereal box filling operation used as a class example. The following description is the same as used in class. The reset switch does not exist, and will be simulated by using the forcing function of the Logix Designer or Step 7 software (the switch/lighting board has only 4 switches). Section F of the Studio 5000 and Step 7 programming guide documents explains how to force inputs. You will be required to manually change the limit switch and the weight sensor switch (SW3 is limit switch, SW4 is the weight sensor). Demonstrate the PLC operation to the instructor. You will need to define the tags as listed below. Put comments in your ladder. The programming guides explain how to add comments. Design a ladder logic diagram to control for the following cereal filler machine. A figure of the system is shown below. Upon initial startup, motor M1 runs until an empty box is the proper position, which is detected by the limit switch, LS. Wait 2.0 seconds and then fill the box until the weight sensor detects a full box. After the box is filled, wait 3.0 seconds to continue to the next box. If the stop switch is pressed at any time, the box filler is paused at the current step. When the start switch is pressed while the operation is paused, the box filler should resume the suspended step. When the box filler is paused, the motors should be shut off and the filler solenoid should be turned off. When paused, timers should continue to run, but do not advance to the next step until the operation resumes. A separate reset switch is provided which resets the timers and any internal steps so that when the start switch is pressed, no box is assumed to be in the filling position. The reset switch should be ignored if the box filler is running. Motor M2 runs continuously (unless paused). Input and output assignments: Start pushbutton, N. O., ON when starting Stop pushbutton, N. C., OFF when stopping Limit switch, N. O., ON (closed) when box in position Weight sensor switch, N. O., ON (closed) when box full Reset, N.
