Course Details

This practical course covers the essentials of SCADA and PLC systems, which are often used in close association with each other. A selection of case studies is used to illustrate the key concepts with examples of real-world working SCADA and PLC systems in the water, electrical, and processing industries.

This is an excellent opportunity to network with your peers, as well as to gain significant new information and techniques for your next SCADA or 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.

Our focus is on the generic PLC and uses the open programming IEC 61131-3 standard. We will give you 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 who expect to become involved in some or all aspects of PLC installation. You will get 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 broader perspective for larger and more challenging tasks ahead. The information included advances from the basics to challenge even the most experienced engineer in the industry today.

The course is composed of 12 modules, covering topics such as SCADA software configuration, installation,  troubleshooting and network security issues, telecommunications links, Industrial Ethernet in SCADA systems, PLC hardware and installation criteria, writing PLC programs using ladderlogic, and troubleshooting for PLC systems.
