Course Description

This unit covers development, installation and testing of programs for programmable logic controllers (PLC) for a system requiring extended control functions. It encompasses working safely, applying knowledge of control systems, control system development methods, ladder logic control functions, using ladder instruction set, following written instructions and documenting program development and testing activities.


National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:

UEENEED007B Develop, enter and verify programs for programmable logic controllers using ladder instruction set

Element:

Develop control system and enter and test program

Performance Criteria:

1. OHS procedures for a given work area are identified, obtained and understood through established routines and procedures.
2. Established OHS risk control measures and procedures are followed in preparation for the work.
3. Safety hazards that have not previously been identified are reported and advice on risk control measures is sought from the work supervisor.
4. Control system scenario is determined from job specifications of the process/plant/machine to be controlled, and through consultation with appropriate person(s).
5. Equipment, software and testing devices needed to carry out the work are obtained and checked for correct operation and safety.
6. Installation of programmable controller is checked for compliance with regulations and job specification.

Element:

Verify, document and report programming activities

Performance Criteria:

1. Established OHS risk control measures and procedures for carrying out the work are followed.
2. Circuits/machines/plant are checked as being isolated where necessary in strict accordance OHS requirements and procedures.
3. Control solutions are developed and documented based on the specified control mode and using acceptable methods for designing control systems.
4. Developed control system is converted to an appropriate form, such as flow, state and ladder diagrams, using a personal computer and software applicable to the programmable controller into which the program is to be entered.
5. Program is entered into the programmable control using a personal computer and appropriate software.
6. Entered instructions and settings are tested as meeting those specified in by the control system scenario.
7. Appropriate methods and tools are used to test control systems and operating faults and anomalies are identified and rectified.
8. Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.

Element:

Prepare to develop, enter and verify program

Performance Criteria:

1. OHS work completion risk control measures and procedures are followed.
2. Program is transferred from a programmable controller to an external medium for storage.
3. Control system specification and program are documented in accordance with established procedures.
4. Work completion is reported and appropriate personnel notified in accordance with established procedures.


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.
