Lab 10: PLC Programming For this final laboratory, your job is to program a PLC to accomplish two specific tasks. Each lab section will have a separate set of tasks. For full credit, your program must demonstrate successful operation of the PLC code using SimPLC. To that end, save your program using the "P" option in SimPLC. Add your name to the filename and submit that file via Blackboard. A GTA will then exercise your program using SimPLC. The cylinders, the switches, and their normally open/closed character are shown in the figure below. X2|NO) ) Controlled by Y1 Controlled by YO XONO PLC Solenoid Valves or yea Controlled by Y2 Controlled by Y3 PLC Program #1: Figure 1. Solenoid and Limit Switch Assignments Push C40 as the "Start" button. Tuesday Assignment Extend and retract the cylinder controlled by Y1 three times. Each time that Y1 is extended, it should stay extended until cylinder Y3 has fully extended for two seconds and then fully retracted. Upon completion of the third retraction of the Y1 cylinder, the program should stop and both cylinder should remain retracted. If C55 is pressed at any time as a "Stop" button, retract all cylinders and return the system to the startup configuration. *Keep in mind: the limit switches for the Y3 cylinder are normally closed. A good approach to dealing with those is to write (on paper) a program assuming that X6 and X7 are normally open switches. Then, as the final step in the programming process, invert all references to X6 and X7. That is, if you read X6 using a normally open contact, change that to be normally closed. Likewise, if you read X6 using a normally closed contact, change that to be normally open. Then transfer the modified paper program to the SimPLC software. PLC Program #2: If C40 is pressed, extend and retract the cylinder controlled by YO two times. If C41 is pressed, extend the cylinder controlled by YO and keep it extended for three seconds before retracting it.
