Elements and Performance Criteria

1. Identifyindustrial control system
   • Work health and safety (WHS)/occupational health and safety (OHS) requirements and workplace procedures are identified and applied
2. Hazards are identified, risks are assessed and control measures implemented
3. Mode of operation of control system is determined from job specifications and consultations with relevant person/s
4. Equipment, software and testing devices for work are obtained in accordance with workplace procedures and checked for correct operation and safety
5. Installation of programmable controller is checked for compliance with regulations, relevant industry standards and job specifications
6. Develop and enter programs for industrial control system
   • WHS/OHS risk control measures and procedures for carrying out the work are followed
7. Control solutions are developed and documented based on operational mode and using acceptable methods for designing control system containing numeric variables and values
8. Control solution is entered using information technology and appropriate software
9. Program control values are assigned using applicable numbering systems and codes
10. Programs are written to read and write analogue signals
11. Arithmetic functions are used to scale analogue inputs to a specified input range
12. Arithmetic functions are used to un-scale an engineering value to drive an analogue output
13. Unplanned situations are responded to in accordance with workplace procedures in a manner that minimises risk to personnel and equipment
14. Monitor, verify and document programming activities
    • Device operation is tested in accordance with workplace procedures and manufacturer specifications
15. Programming is tested in accordance with specified control mode requirements
