DCS Applications, Selection and Troubleshooting Course
Introduction:
This course provides an overview of the development of computer control systems and discusses the architecture of modern DCS offerings in broad terms. It covers various aspects such as hardware, configuration, data communications, user interfaces, and I/O devices. Moreover, the course introduces the general maintenance requirements for DCS, including troubleshooting techniques utilizing DCS self-diagnostics and diagnostic displays available to engineers and technicians. It also addresses the safe and proper procedures for replacing cards, modules, and power supplies.
Additionally, the course delves into different methods of tuning three-term controllers, exploring various Zeigler-Nichols approaches. Practical training sessions are provided, focusing on PLC and HMI programming techniques. Participants will have hands-on experience using cutting-edge simulators such as Allen Bradley SLC 500, Siemens S7, AB MicroLogix 1000 (Digital or Analog), AB SLC5/03, and AB WS5610 PLC simulators.
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
