Instructions 1. For Part 2, cach student will post their * RSL files from Logix Pro to the course eLearn Dropbox for grading. There are TWO problems to the Part 2 portion of the exam. 2. The files must be posted by midnight on Saturday, 15 February 2020. 3. If you have questions, please come to the instructor. PART 2: PROBLEMS-15 Points PROBLEM #1: 5 POINTS 1. Write a documented program for a retentive on-delay time that will turn a light 'on' anytime a switch is closed for an accumulated time of 15 seconds. 2. Use an NO reset pushbutton to reset the timer. 3. Use the I/O Simulator screen and AT LEAST the following addresses to simulate the program: 4. Prepare a fully functional ladder logic program for the task 5. Use addresses that apply to your Logix Pro software program. 6. Use the Logix Pro simulator software to enter the program and validate its operation. 7. You must include tags, addresses, and rung comments in your program. 8. No timers, counters, or sequencers are permitted for this problem at this time. 9. Post your actual Logix Pro rsl file with your LASTNAME and Problem 1 as part of the filename! PROBLEM #2: 10 POINTS Task You are hired to develop a ladder logic program for a push-to-start/push-to-stop operation of a motor The operation of the program is summarized as follows. A. A single momentary normally open pushbutton (1:1/0) performs both the start and stop functions. B. The first time the pushbutton is pressed, internal relay instruction B3:1/11 is latched, energizing output O:2/0. C. The second time you press the pushbutton, internal relay instruction B3:1/12 unlatches instruction B3:1/11, de-energizing output 0:2/0. D. Internal relay instruction B3:1/10 prevents any interaction between instructions B3:1/12 and B3:1/11. E. Prepare a fully functional ladder logic program for the task. F. Use addresses that apply to your Logix Pro software program. G. Use the Logix Pro simulator software to enter the program and validate its operation H. You must include tags, addresses, and rung comments in your program. I No timers, counters, or sequencers are permitted for this problem at this time. J.
