OTSDCS001 DISTRIBUTED CONTROL SYSTEMS - Instrumentation

Distributed Control Systems (DCS) (Ref:OTSDCS001)

Course Objectives

To gain a detailed understanding of the Distributed Control Systems.

Course Description

This course will cover the practical applications of distributed control systems. Included is the relationship between programmable logic controllers and the DCS. Further included is the importance of Human Computer Interfaces (HMI) and advanced control strategies, which would not be possible without the application of a computer. This course is non-specific but will include a number of manufacturers DCS systems, such as Honeywell TDC rage. Each delegate will receive a comprehensive course manual. The concept of field buses is introduced with some study of Foundation of assets management as a tool for proactive maintenance systems.

Who Should Attend

This course is intended for engineers and technicians requiring knowledge of automation and distributed control. A section on trouble shooting methods is also included. Personnel in operations will also find this an invaluable course.

Pre-Requisites

All Attendees should have a sound power generation and electrical background.

Course Outcome

At the end of this course you will be able to maintain a distributed control system.
