Computer Control:
Safe Practice.

Course Content.

• Computers: what they are and how they can go wrong
• Hazards in computer control: introduces the concept of using Hazard and Operability Studies (HAZOP)
• Modelling systems: this covers various tools which are available and of benefit to the design of computer systems
• Principles of safe computer control: introduction to the requirements of safe control systems
• IEC 61508 / 61511: gives a complete overview of the IEC 61508 and 6511 standards
• Establishing integrity levels: IEC 61508 and similar standards require the setting of integrity levels for safety
• Sneak Analysis (SA): a technique for identifying design errors
• Life-cycle specifications: the design life-cycle of typical software-based systems, explains what is to be specified, by whom and when
• Towards safer industrial computer controlled systems: a study of previous incidents and an introduction to a systems tool variation of HAZOP called HAZAPS
• The PES checklists: the HSE PES Guidelines contain a very useful and extensive set of checklists

Computers control every part of modern chemical processing plants, it is vitally important that operators understand the hazards associated with hardware and software errors.

You are introduced to computer architecture, requirements analysis and systems analysis with supporting tools and software concepts and tools. You are trained on software and system testing and validation, software maintenance and redesign and the development of fault tolerant systems.
