DCS Applications, Selection and Troubleshooting Course
Course Overview:
This course amply covers Distributed Control Systems (DCS) and is tailored to the management, configuration and operation roles that are integral to the power and industrial systems.
The hardware and software components of DCS, alarm systems, safety and field communication technologies, and comparison with PLC and SCADA systems will be thoroughly examined.
The course must be taken with a focus on fault finding, redundancy and protective relaying and automation in power system distribution.
The course is relevant for engineers, technicians and instrumentation experts who want to manage DCS systems in power plants, refining systems and industrial processing systems.
Course Objectives:
By the end of the training, participants will be able to:
- Apply in-depth knowledge and skills in DCS systems and implement systematic applications, selection, and troubleshooting techniques and methods Identify the DCS hardware & software particularly the traditional process controllers, programming, execution time, configuration, etc.
- List the parts and configuration of the SCADA system and determine its basic architecture and levels of hierarchy
- Differentiate DCS from PLC and SCADA and discuss their features and functions
- Determine the types of DCS used in petroleum refining processes and explain their specific function in each process
- Employ the concepts of alarm management system including its types, features, architecture, and functions
- Discuss the concepts of humans in control and identify the factors that contribute to the following concept
