The document provides instructions for an assignment on programmable logic controllers (PLCs). It includes 4 tasks: 1) summarizing lab exercises completed with a PLC trainer kit, 2) designing a PLC program for a simulated system, 3) comparing using a PIC microcontroller instead of a PLC, and 4) comparing two PLC simulation software programs. It outlines the learning outcomes and criteria the assignment will be assessed on.

- 4. UNIVERSITY OF TECHNICAL EDUCATION HCMC PLC Assignment 2 brief 2014 4 Scenario You are employed as a sales engineer of a company which is a re-seller of automation and industrial control products such as PLCs, sensors, pushbuttons, AC drives/motors, enclosures, operator interfaces, and much more. You are asked demonstrate your knowledge and skills with PLC programming and design. Task 1: a) You should have completed all the exercises in the lab using PLC trainer kit during your lab. For each lab, you should - List the input and output devices - Produce a wiring diagram to the PLC and its power circuit - Produce a table of tags, input and output addresses - Produce a PLC program rather than the one given if possible - Show your debugging and testing processes List of exercises: 1. Latches 2. Burglar Alarm (OR-GATE) 3. Microwave Oven (AND-GATE) 4. Fuel Tank (NAND-GATE) 5. Fuel Tank (NOR-GATE) 6. ASTRO Sensors (XOR-GATE) 7. ASTRO Sensors (XNOR-GATE) 8. Emergency Stop (NOT-GATE) 9. Traffic + Walk Light 10. Conveyor Belt 11. Microwave Oven Timer 12. Washing Machine 13. Mixer 14. Room Capacity Alarm

Elevator (Note: Please refer to the attached Lab sheets for more information) b) While doing your lab exercises you have used testing and debugging techniques. Discuss methods of testing and debugging your programmes and explain the usefulness of these methods. Task 2. For the simulated system on FX Trainer assigned (please refer to the list), 1. List all the input and output devices and its brief function 2. Describe the operation of the system 3. Produce a list of tags and labels for all the inputs and outputs. 2. Produce a flow chart/state diagram style program. 3. Produce a truth table showing only the conditions that turn the motors on. 5. Produce a circuit diagram for the hardwired control circuit. 6. Produce a ladder logic diagram for the control circuit. Transfer it to the FX Trainer Simulator test the programme. 9. Demonstrate the system working. Task 3. For saving cost, you are asked to control the system in Task 2 using a PIC or other microcontroller. Describe what you would change and compare the two systems in term of cost, design complexity and operation Task 4. Describe the two PLC simulation software you have used and compare their operation and functionality, advantages and limitations Evidence checklist Summary of evidence required by student Evidence presented Task 1, 2, 3, A report written in a formal style, including a contents page indicating the different report tasks and sections. A bibliography with references must be supplied using the Harvard System of referencing.

- 7. UNIVERSITY OF TECHNICAL EDUCATION HCMC PLC Assignment 2 brief 2014 7 Do not leave things such as printing to the last minute – excuses of this nature will not be accepted for failure to hand-in the work on time. You must take responsibility for managing your own time effectively. If you are unable to hand in your assignment on time and have valid reasons such as illness, you may apply (in writing) for an extension. Failure to achieve a PASS grade will results in a REFERRAL grade being given. Take great care that if you use other people’s work or ideas in your assignment, you properly reference them in your text and any bibliography. NOTE: If you are caught plagiarizing, the University policies and procedures will apply.
