Description
This unit describes the performance outcomes, skills and knowledge required to write programs for programmable logic controllers (PLCs).

It requires the ability to work safely, apply knowledge of control systems, program control functions and develop and test control programs using a range of programming language approaches developed for PLCs.

This unit of competency applies to a person working in an engineering environment where programmable logic controllers are used for automating processes in manufacturing, process control, building services, laboratories etc.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.

Elements and Performance Criteria
Prepare to develop a PLC program.
  • 1.1 Established occupational health and safety (OHS) requirements and risk control measures and procedures for the work area are followed
  • 1.2 Safety hazards, which have not previously been identified, are documented and risk control measures devised and implemented in consultation with appropriate personnel
  • 1.3 Control program and input/output interfacing requirements are determined from job specifications and consultation with appropriate personnel
  • 1.4 Equipment and software needed to carry out the work are obtained and checked for correct operation and safety
  • 1.5 Installation of programmable controller is checked for safety compliance and against job specification
Develop, write and test control program
  • 2.1 Plant or machines circuits are checked as being isolated where necessary in accordance with OHS requirements and procedures
  • 2.2 Control solutions are established and documented based on the specified control mode and using appropriate methods for designing control systems
  • 2.3 The developed control system is converted to an appropriate form for the programmable controller using relevant software
  • 2.4 Program is entered into the programmable controller using a computer and appropriate software
  • 2.5 Entered instructions and settings are tested as meeting those specified in the control system scenario
  • 2.6 Appropriate methods and tools are used to test the control systems and operating faults and anomalies are identified and rectified
  • 2.7 Methods for dealing with unexpected situations are selected on the basis of safety considerations and specified work outcomes
Finalise control program
  • 3.1 Program is transferred from a programmable controller to an external medium for storage
  • 3.2 Control system specification and program are documented in accordance with enterprise procedures
  • 3.3 Work completion is reported and appropriate personnel notified in accordance with enterprise procedures
