Practical Distributed Control Systems (DCS) for Engineers and Technicians Course
Introduction:
This manual will cover the applications of the modern distributed control system (DCS). Whilst all control systems are distributed to a certain extent today, there is a definite merging of the concepts of DCS, Programmable Logic Controller (PLC), and SCADA. This course is designed to provide the participants with an overview of the technologies and applications of Distributed Control System. The course will cover the relationship between the programmable logic controller and distributed systems. The HMI (Human Mechanical Interference) will be discussed in terms of its functionality and importance to the operation of the DCS. Interfacing to computers for implementing advanced control strategies beyond the capacity of the DCS controllers will be covered.
Course Objectives:
- A solid understanding of the architecture and operation of Distributed Control Systems (DCSs)
- The ability to design the overall DCS and process control system
- Better specification of planned DCSs
- Improved process performance for your plant
- An Understanding of the key ergonomic issues in design of operator displays
- How to apply advanced control strategies to your plant control system
- More effective use of your existing DCS process control capabilities
- How to design and create a consistent and effective alarm philosophy for your installation
- To recognize and deal with human problems in interfacing to alarm systems
