Introduction
Different plants have different control requirements, and it is generally acknowledged that there is no one technique that will solve all the control problems that are manifest in a modern plant.
Despite the rapid growth in the use of PLC and SCADA systems, the modern Distributed Control System (DCS) still offers many benefits.
These include: increased integrity (reduced process downtime); reduced engineering time; abnormal situation management; intelligent alarm management; and pre-engineered solutions for the implementation of Advanced Process Control (APC) strategies.
Course Objectives
This workshop, Distributed Control Systems is designed to provide engineers and technicians with an overview of the modern DCS and how to deal with a variety of issues concerning alarm management, operator performance feedback, improved control, and cyber security issues.
On successful completion of this workshop delegates will have:
- ability to input to the design and specification of the DCS and process control system
- understanding of the key ergonomic issues in design of operator displays
detail the key trends that underpin modern distributed control systems - a better understanding of the design and creation of consistent and effective alarm philosophies
- a recognition of how to deal with human problems in interfacing to alarm systems
- the ability to benchmark your alarm system performance
- the ability to correctly apply both open and closed Loop Tuning
- gain insight into the challenges faced by cyber security
