Description

All industrial and manufacturing processes operate under the control of a variety of automated and computer-based control systems. As process control technology evolves rapidly, and the digital age of Fieldbus instruments emerging, it is necessary for technical staffs who are involved in the field of process control and instrumentation to continuously upgrade their technical skills and knowledge.
This course is designed to help students to understand the basic principles and importance of process control in industrial process plants; Digital Signal Processing, Stability, Programmable logic controllers (PLC) and various control functions.
After completing this course, Students will have the professional knowledge to ensure that the systems and processes operate effectively, efficiently and safely.

Instructor

Allan Butler

Allan worked for Curtin University and Australian Defense Force before joining SECWA in 1990, where he worked in remote power stations commissioning and decommissioning various power stations in the north of Western Australia. In 1992, he joined the DBNGP as their Corrosion Protection Officer, from which he was internally promoted up the organisation holding various roles nationally and state based for the various owners of the DBNGP. The roles varied across operations, maintenance and projects where he has had direct and indirect responsibility. 
Allan was the project manager on a significant SCADA upgrade which controlled one of Australia’s largest SCADA systems, spanning some 1600 kilometres and supplied natural gas to the Perth Metropolitan Area from the Carnarvon basin.
Allan has recently completed a Post Graduate Diploma in Control Systems and Project Management and is currently completing a Master’s Degree in Automation Control and Business Management.
Allan has been elected to the grade of senior member of the IEEE and also holds memberships with the Australian Institute of Project Management and currently sits on the ISA committee for alarm management.
