Learning Outcomes
Details of Learning Activities
Students will participate face to face in
• classroom tutorial activities to consolidate the theory of Fluid Power concepts, PLC operating principles and introduction to circuits designed for linear pneumatic actuators and asynchronous sequential machine control systems.
• Practical activities to develop skill in PLC basic programming, design basic logic control and construction of control circuits, test to verify the performance specification, diagnose and debug faults, verify the completion of the commission.
• Work performance simulation projects involving the design and construction PLC circuits, development of testing procedure to verify the performance specification, diagnosis of faults in the systems and repair the fault. Specifications will be provided with work simulation (team or individual basis) or may be negotiated to suit a workplace based application
Projects may be undertaken as part of a team or individual basis.
It is expected that students would require approximately 20% of course hours to be allocated for independent study to do project research, design, construction, testing and problem solving activities.
