Elements and Performance Criteria
- Prepare to develop programs for supervisory control and data acquisition systems.
- OHS procedures for a given work area are identified, obtained and understood through established routines and procedures.
- Established OHS risk control measures and procedures are followed in preparation for the work.
- The extent of the SCADA system is determined from design brief and process specifications.
- Process data are analysed for development of graphical design/mimic diagrams.
- PLC analogue and digital addresses are related to tag database.
- Tag data types are configured in the database.
- Graphic objects are created and where appropriate are added to a graphic library. (See Note 1)
- Consideration is give to the security requirements for the SCADA system to prevent access by unauthorised personnel.
- The SCADA system is configured to provide appropriate reporting mechanisms.
- Equipment, software and testing devices needed to carry out the work are obtained and checked for correct operation and safety.
- Develop and enter programs using dedicated supervisory control and data acquisition software.
- Established OHS risk control measures and procedures for carrying out the work are followed.
- SCADA software is used to develop human-machine interface (HMI) of processes.
- Supervisory control functions, data acquisition components and automated tasks are programmed using SCADA software.
- Data is manipulated within the SCADA software.
- Alarms and limits for process variables are identified and programmed accordingly.
- Trends for process variables and limits are programmed accordingly.
- Reports are configured to display/print appropriate information.
- User rights/security is configured to provide appropriate access to the different sections/controls of the SCADA system.
- Methods for dealing with unexpected situations are selected on the basis of safety and specified work outcomes.
- Monitor, verify and document programming activities.
- Device operation is tested in strict accordance OHS requirements and procedures.
- Entered objects and settings are tested as meeting those specified in the design brief.
- SCADA software tools are used to test and monitor programs and operating faults, anomalies are identified and rectified.
- OHS work completion risk control measures and procedures are followed.
- SCADA system specification and program are documented in accordance with established procedures.
- Work completion is reported and appropriate personnel notified in accordance with established procedures.
- Note.
- Graphic libraries are typically part of vender software for SCADA systems.
