Instrumented Security Systems - Design, analysis and justification - EC50
This course is focused on the engineering requirements to specify, design, analyze and justify the use of safety instrumented systems for the process industry. Students will learn how to determine comprehensive levels of functional safety and how to evaluate whether existing or proposed systems meet performance or performance requirements. International Professional Certification Course for Safety Instrumented Systems - Design, Analysis and Justification - EC50.
This course focuses on the engineering requirements for the specification, design, analysis, and justification of safety instrumented systems for the process industries. Students will learn how to determine security integrity levels and assess whether proposed or existing systems meet the performance and documentation requirements defined in the ISA84 standard (IEC-61511).
This course is required for the ISA / IEC-61511 SIS Foundation Specialist Certificate. When you register for the course, the certificate exam is included with your registration.
Those who successfully complete this course and pass the exam will receive the designation of the ISA / IEC-61511 SIS Foundation Specialist Certificate.
You will be able to
- Differentiate between process control and security control.
- Implement the ISA84 standard (IEC-61511)
- Evaluate the risk levels of the process.
- Select safety integrity levels (SIL) for instrumented safety functions (SIF) using a variety of techniques
- Analyze the performance of different logical system technologies.
- Analyze the performance of various sensor configurations, logic and final elements, as well as the impact of diagnostics, test intervals, common cause, system size, imperfect manual tests and omission
- Determine the optimal test intervals of the system.
- Specify and select safety instrumented systems.
- Apply documentation requirements for process safety management, regulations and industry standards.

- Scope and life cycle of security: management problems | Life cycle design |
- Security layers: security layers independent | Separation of control and safety
- Risk, hazard analysis, safety integrity levels: hazard identification | Risk assessment | Selection of security integrity levels | Protection layer analysis
- Failure modes and reliability concepts: safe versus dangerous | Failure mode versus technology | Failure rates | Modeling techniques | Test intervals | Fault tolerance requirements
- System Technologies: tire | Relay | Microprocessor | Field devices | Certification | Prior use
- System design: requirements specification | General design issues (environment, interfaces, derivations, reboots, etc.)
- Operations and maintenance: installation | Operation and Maintenance | Test | Change management | Dismantling
Practical exercises in class
- Calculate device failure rates
- System performance model for relays and software-based logic systems
- Model the impact of different configurations, field devices, automatic diagnostics, manual test intervals, common cause and imperfect manual test and omission
- Determine the SIL (safety integrity level) of a sample of functions and design a system to meet performance requirements
- Copies will be provided in the classroom of ISA / IEC-61511 standards for use during the course
A hand / scientific calculator should be taken to class.
