ISA's CyberU online instructor-led training course offers the benefit of a high quality ISA training course with the added advantage of studying at your own pace in the office, at home or while traveling.

This online course utilizes online training modules, additional text materials, online evaluations, and email discussions. Students will have access via email to an instructor and have an opportunity to participate in live Q&A sessions with the instructor and other class participants. The 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 safety integrity levels and evaluate whether proposed or existing systems meet the performance requirements.

This CyberU course runs for seven (7) weeks. You will have access to seven online modules for a web/audio session. Each module takes approximately 60 minutes. Your course syllabus will guide you through the course modules, provide assignments, and the schedule for live Q & A sessions.

You will be able to:

  • Define safety instrumented system.
  • Discuss how regulations have resulted through lessons learned from high profile process industry accidents.
  • Determine which ANSI/ISA, AIChE, and IEC guidelines and standards are relevant in industry.
  • Identify the Scope of ISA 61511
  • Discuss strategies for the management of functional safety
  • Identify the stages of the safety design life cycle.
  • Identify available safety layers for an IACS
  • Discuss the importance of "defense in depth" concept
  • Identify how SISs are used to reduce risk.
  • Categorize risk using a PHA
  • Determine SIL using qualitative methods
  • Determine performance requirements for each SIL
  • Conduct a LOPA
  • Discuss LOPA methodology
  • Develop guidelines for LOPA
  • Determine risk tolerance
  • Identify resources for cyber security in an IACS
  • Identify failure modes and the risks involved with each
  • Identify hardware modeling techniques (SIL verification.)
  • Explain the impact of redundancy on failure rates.
  • Demonstrate the use of fault tolerance tables.
  • Develop an SRS
  • Explain the pros and cons of relay logic systems
  • Explain the pros and cons of microprocessor systems (PLC)
  • Discuss the pros and cons of pneumatic systems
  • Identify typical field devices in an IACS
  • Discuss impact of field devices on system performance
  • Explain Center for Internet Security (CIS) Benchmarks
  • Explain pros and cons of using certification vs prior use devices.
  • Explain the FAT process.
  • Explain installation and commissioning process.
  • Explain the validation process
  • Identify priorities of the operation and maintenance phase.
  • Identify safety requirements for MOC
  • Identify documents to maintain for SRS

You will cover:

Each course module has been pre-recorded by your instructor, so that you can access on your schedule. Each module is a web/audio session that takes approximately 60 minutes.

Covers high profile process industry accidents, the legislation that resulted and various lessons learned

Module 2/Week 2: Hazard and Risk assessment, Selecting SILs
Covers concepts and benefit of independent safety layers, hazard identification, risk assessment and safety integrity levels (SIL)

Module 3/Week 3: Layer Of Protection Analysis (LOPA) and cybersecurity
Covers the semi-quantitative method of determining safety integrity levels called LOPA

Module 4/Week 4: Reliability and Modeling Issues
Covers reliability issues and helps make sense of the minimum hardware fault tolerance requirement tables in the standard

Module 5/Week 5: SRS and Logic Solver Technologies
Covers the safety requirements specification (SRS) and the pros and cons of pneumatic, relay and microprocessor logic systems

Module 6/Week 6: Field Devices, Certification, Misc Design Issues
Covers field devices, their impact and the differences between using certified vs. proven-in-use devices.

Module 7/Week 7: FAT and beyond
Covers factory acceptance testing, installation, commission, validation, operations, maintenance, testing, bypassing and management of change

Features of ISA CyberU online course:

Online Pre-recorded Course Modules

Your instructor has pre-recorded each course module so that you can access the course presentations on your schedule. Each module is a web/audio session that takes approximately 60 minutes.

Ask the Expert

Interact with your expert instructor, via email throughout the course and through scheduled live Q& A sessions. You can expect a reply to your email within 24 hours. This email address is active during the entire course duration.

The Q&A sessions provide an opportunity for you and your classmates to speak one-on-one with the instructor. You will have an opportunity to ask any questions you may have about the course material and interact with your fellow classmates.

Class Discussions

You will be invited to subscribe to a course listserve that includes course participants. You can use this listserve to post questions and share experience relevant to the course with other class members.

Course Assignments and Exams

  • Take the course pre-test before you begin studying the course material to get a better understanding of areas that you will want to focus on more during the course.
  • Homework assignments for all modules will be indicated on the syllabus. The homework assignments are designed to help expand your understanding of the course material.
  • Complete the final exam for the course in order to receive Continuing Education Units (CEU) credit. The final exam will be taken and scored online. You must receive at least 80% on the course exam to receive CEU credit.
  • Continuing Education Units (CEU) credits are awarded to all students who successfully complete the final course exam.
