This comprehensive course covers the essentials of SCADA and PLC systems, which are often used in close association with each other. A selection of case studies are used to illustrate the key concepts with examples of real world working SCADA and PLC systems in the water, electrical and processing industries.
This course will be an excellent opportunity to network with your peers, as well as to gain significant new information and techniques for your next SCADA / PLC project. Although the emphasis of the course will be on practical industry topics highlighting recent developments, using case studies, the latest application of SCADA, PLC technologies and fundamentals will be covered.
The inevitable question is which PLC is being used. We present this course focusing on the generic PLC and use the open programming IEC 61131-3 standard. For specific examples we use the Allen Bradley range, but are not selling Allen Bradley or for that matter any other PLC!
This course is designed to benefit you with practical up-to-date information on the application of PLC systems to the automation and process control industries. It is suitable for people who have little or no exposure to PLCs, but expect to become involved in some or all aspects of PLC installation. It aims to give practical advice from experts in the field, to assist you to correctly plan, program and install a PLC with a shorter learning curve and more confidence. While the course is ideal for electricians, technicians and engineers who are new to PLCs, much of the material covered will be of value to those who already have some basic skills, but need a wider perspective for larger and more challenging tasks ahead. The information covered advances from the basics to challenge even the most experienced engineer in the industry today.

In order to meet the exacting demands of the oil and gas, mining, manufacturing and downstream processing industries, modern plants are equipped with systems and devices which are needed to measure and regulate variables such as temperature, pressure, flow, humidity, liquid level, velocity and density. Industrial Automation provides the technology to control and monitor a process plant using such concepts as feedback, cascade, feedforward and advanced process control. Here at the Engineering Institute of Technology (EIT), we have developed industry-focused programs in the form of vocational diplomas, advanced diplomas and graduate certificates, all the way up to Masters level in the higher education sector.
There is a critical shortage of automation, instrumentation and control engineers, technicians and technologists around the world now due to the retirement, restructuring and rapid growth in new technologies and industries. The respected International Society of Automation (ISA) organization estimated that at least 15,000 new automation engineers are needed annually in the USA alone.
In keeping with the philosophy of EIT, students in this school are exposed to the practical, up-to-the-minute knowledge and skills demanded by leading industries worldwide, with online instrumentation courses. EIT does not just cater to a generic student body, instead all of our online instrumentation courses are specific to industry. The programs cover a large range of topics and are suited to anyone needing an intensive and practical look at all facets of industrial automation, instrumentation and process control.
The short courses that form part of EIT's professional development series are designed to provide students with critical knowledge and practical tools that can be immediately applied to the workplace. They are ideal to up-skill and/or cross-skill in a particular area or technology and are not accredited programs.
Students in EIT's School of Industrial Automation, Instrumentation and Process Control study subjects which include: process control, instrumentation, control valves, process plant layout and piping design, tuning of process loops, SCADA, PLCs, advanced process control (APC), boiler control, hazardous areas, safety instrumentation (IEC 61511 and IEC 61508), HAZOPs, industrial data communications, networking, deviceNet and Fieldbus, industrial wireless, radio telemetry systems, shielding/EMC/EMI, and noise reduction.
