1. New items for final exam

2. An indication of your current comfort level to the final exam is your responses to the following 8 practice question set. Pre-presentation Self Assessment Activity If there are questions in the set that generate some discomfort, you should return to the White Board Roadmap option on this site and run the partially animated presentation on that topic.

3. 1. Wire a N.O. active low TSH and a N.C. active low PSH to an input module of a PLC. Wire an active high motor starter circuit to the output module of the same PLC and then, using ladder (logic) language, program the PLC so that the motor will run only when both limit sensors are in alarm. Include the program, the wiring diagram, and the I/O map as documentation. 2. Questions to promote an efficient pre-final exam review of topic to be assessed on the final exam. Wire a N.O. active TSH and a N.C. active high PSH to an input module of a PLC. Wire an active high motor starter circuit to the output module of the same PLC and then, using ladder (logic) language, program the PLC so that the motor will run when both limit sensors are in alarm. Include the program, the wiring diagram, and the I/O map as documentation. 3.Design an instrument system that includes a programmable controller that will include a normally closed Start Push Button and a normally open temperature high limit sensor.

4. 4.Redesign your system in question 3 so that the button is wired the opposite way it was in question 1 and the senor has the opposite activity. 5.Write a ladder program for each of your designs in questions 3 and 4. Review questions for exam topics 6.Write a ladder (logic) program rung that will properly execute the following instrument system function diagram. 7. 8. Write a timer ladder (logic) program rung that will make program address, M-01, passive when a programmed override time has been met. Write a Counter ladder (logic) program rung that will make program address, M-21, active when a FQI has responded a programmed number of pulses. I-0,2 O-3,2 I-01 I-6,5 I-6,6 M-03 M-21
