Overview
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.
