Evolution in the Design of Safety Critical Supervision and Alarm Systems

Description

A technical and thorough course on the design and management of supervision and alarm systems in industrial contexts, with an emphasis on regulatory standards and emerging technologies.

Objectives

1. Understand the general principles of design and management of supervision and alarm systems
2. Learn about and understand the architecture of machine and plant control systems
3. Assess and manage the risks associated with HMIs, SCADA and DCS systems, and implement preventive measures
