Summary
Causes a health hazard in the event of damage to property or the environment can be very diverse, as well as technical measures to prevent their occurrence or mitigate their consequences, therefore it is necessary to distinguish between different types of security.
Due to the complexity of security problems in the industry has introduced IEC 61508 is relatively new term so-called: functional safety, which must respond to the inputs of the system, including the likely operator error, hardware or software failure, and environmental changes.
In connection with the development of industrial automation, functional safety particularly important for so called: safety related parts of control systems, i.e. for all parts of the control circuits, which ensure execution of security functions and whose term failure could cause a hazardous situation with a high level of risk.
Learning Outcomes of the Course Unit
Graduate of this subject gets a basic understanding of a set of standards IEC 61508 related functional safety. This knowledge and skills subsequently applied to practical examples and during the formation of the semester work.
Course Contents
Lectures:
1. Introduction to technical standardization.
2. Introduction to the series of standards IEC 61508 functional safety, historical development.
3. Fundamentals of construction in accordance with IEC 61508, the safety lifecycle and its phases.
4. Phase of functional safety lifecycle. Semester work.
5. Management of functional safety objectives and requirements.
6. Implementation of functional safety management into the organizational structure of the company.
7. The qualifications of persons within the functional safety.
8. The Management and technical of activities of functional safety.
9. Evaluation of the probability of failure of hardware, verification for E / E / PE, the definition of basic subsystems, systems architecture description.
10. Computation of diagnostic coverage and the share of safe failures.
11. The effects of systematic failures associated with hardware E / E / PE, decommissioning and disposal.
12. Practical examples - simple calculation model example SIL verification for E / E / PE system.
13. Practical examples - technology pressure reservoir with the control system.
14. Control of semester work.

Exercises:
1. Introduction - practical application of standards.
2. Concept of risk analysis and risk assessment, safety integrity level assignment.
3. Assignment of semester work.
4. Diagram risks for determining the safety integrity level, the principle of protective layers.
5. Definition of the overall subject, hazard analysis and risk requirements of overall security.
6. Assign security requirements, planning, overall installation and commissioning.
7. Liner-staff organizational structure, functional organizational structure, divisional organizational structure. Consultations of semester projects.
8. Demonstration role of dependent and independent entities under the management of functional safety.
9. The method of calculating the probability of failure on demand architecture used in the IEC 61 508.
10. Practical example of technology pressure container - risk analysis to determine the level of integrity, system structure, determining architecture subsystems, the calculation of the probability of default.
11. Example pressure container with the control system - calculation of total system performance, assessment software, control test.
12. Written work.
13. Check the projects.
14. Submission of semester projects. Control tasks.
