Overview:
At one time, taking the thousands of pieces of information in a plant and displaying it on some kind of information system was a real challenge and in fact, impossible. With the development of Distributed Control Systems (DCS) it is now easy to take all the information and organize it in a hierarchical system.
DCS displays information on a computer and allows process operators to run the process, making the process information available to other people in the plant. Once the DCS converts the process information to personal computer language, it can be distributed to everyone on the plant site and to other parts of the organization that may be located anywhere in the world.
Training Objective:
In this course participants will learn about the main characteristics of the DCS systems. They will become familiar with the DCS hardware and how it is connected together to make up the basis of the DCS. Once the hardware is installed and tested, the participants will learn about programming the DCS software. Once the software is configured the participants will become familiar with the DCS accessories, such as alarm and data reporting systems.
