Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Client
Client may be:
internal or external to the designer’s organisation
Parameters to the brief
The design brief may include the design of new equipment or fault analysis, rectification or modification to an existing design. Parameters to the design brief may include:
determination of the degree of innovation and creativity expected by the client
design process limits and budgets
product cost limits and budgets
performance specifications
equipment availability, capacities and restrictions
specified administrative, communication and approval procedures
other special features and limits in the design brief
PLC solutions
PLC solutions may include consideration of:
I/O capacity
I/O module types:
discrete
special
signal conditioning
interface requirements
control functions
system integration
communication protocols
automation safety
network topology
programming languages
Applications
Applications may include:
control of machines, equipment or processes that may have thermodynamic, hydrodynamic, fluid power or mechanical system elements
control functions:
digital
analog
feedback loops
communications networks and remote control
OHS, regulatory, sustainability and environmental issues

OHS, regulatory, sustainability and environmental issues may include:
OHS Acts and regulations
relevant standards
industry codes of practice
risk assessments
registration requirements
safe work practices
minimising ecological and environmental footprint of process, plant and product
maximising economic benefit of process plant and product to the organisation and the community
minimising the negative OHS impact on employees, community and customer
state and territory regulatory requirements

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
interpret features and functions of the application and parameters to the brief or contract
determine sustainability, automation safety, OHS, regulatory and risk management
research and test system components
investigate and measure, model and calculate for options
generate and evaluate a range of solutions
design PLC system solution
implement systems thinking, continuous improvement and constraint and contingency management
select system components
prototype and systematically program and test system component function
ensure automation safety, using appropriate licensed technical and professional assistance
communicate, negotiate and review with stakeholders and client throughout process to obtain agreement on proposal and sign-off on design
document design with drawings, specifications and instructions.
Context of and specific resources for assessment
This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is, the candidate is not in productive work, then a simulated working environment must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
