  S1E56 Clause 13.2.4 to 13.2.7 09.09.2026 37นาที

  During the Factory Acceptance Testing (FAT), you're going to find issues.  You can’t fix them on the spot— you need to trace each one back to wherever it originated in the safety lifecycle and correct everything downstream from that point.

  S1E55 Clause 13 25.08.2026 57นาที

  Factory Acceptance Testing is where Ed Marszal picks up in Clause 13, starting with an admission: the clause title may be wrong, since 13.2 is called Recommendations when every other point-two clause in the standard states requirements. Scope matters here FAT applies to the SIS logic solver, the engineered, customized subsystem, not off-the-shelf field devices like a pressure transmitter. Ed works through the objective's three notes, then the twelve-bullet planning list in 13.2.2: black box functionality, performance, environmental, and power-failure testing, plus test cases, dependencies on other systems, personnel competency, hazard assessment, and documenting results, with a nod to using Kenexis® Open-PHA® checklists or Kenexis® Open-Audit™ to run it. The episode ends at 13.2.3's one-sentence requirement to test a defined version, with 13.2.4 through 13.2.7 held for next week.

  S1E54 12.5 and 12.6 11.08.2026 51นาที

  Clause 12.5 closes out the software section with the meat of application program testing: verification planning tied back to Clause 7, an independent competent-person review, and nine bullet points covering conformance testing, exercising all parts of the program, representative data ranges, negative testing, timing and sequence checks, communication overload stress tests, and integration with the actual logic solver hardware. Ed Marszal walks through each one, then covers I/O data mapping verification, impact analysis for mid-testing fixes, and the seven-item documentation requirement that insists on recording passing tests, not just failures. Clause 12.6 closes with methodology and tools: complying with vendor safety manuals, and five purposes your methods, techniques, and tools must serve. Throughout, Ed threads a running argument for automating this testing with tools like ProLyTx, tied to the newly rebranded Kenexis SIS software.

  S1E53 12.4.3 and 12.4.4 04.08.2026 33นาที

  The best and safest way to write software is to break things down into tested reusable modules...
• 
  S1E52 12.4 16.06.2026 44นาที

  At the risk of saving you from hours of unnecessary work, in our latest episode, we tackle a surprisingly common habit: trying to do application program design and implementation at the exact same time. Tune in to hear why this happens, why it's a problem, and how to stop doing it!Grab your headphones and let's streamline your workflow!
• 
  S1E51 12.3.4 pt2 to 12.3.5 01.06.2026 42นาที

  Designing software comes before writing it. We're still inthe design phase and will be for a bit…Listen in to this episode as the discussion of this topic continues.
• 
  S1E50 12.3 18.05.2026 53นาที

  To clarify, the standard separates application program design from its actual implementation.  It feels like a bit much…Join us for our 50th episode as this is discussed in more detail!
• 
  S1E49 12.2.6 to 12.2.9 04.05.2026 51นาที

  The startup sequence of a Safety Instrumented System (SIS)represents a critical vulnerability phase, as it triggers initialization code that rarely executes during steady-state operation.Join us as this important topic is discussed in this episode.
• 
  S1E48 12.1 to 12.2.5 30.03.2026 47นาที

  The first technical safety standard ISA84 didn’t talk about programming in it at all.  So, we decided when we added it, wewould wildly over complicate the situation…
• 
  S1E47 11.9.3 to 11.9.5 25.03.2026 52นาที

  Do not incorporate human failure into your SIL verification calculations, it will actually lead you to do the wrongthing.In this episode, this important topic is covered by our industry expert as he discusses these sections and shares his vast knowledge and experience.
• 
  S1E46 11.9.1 and 11.9.2 17.03.2026 1ชม. 2นาที

  When it comes to SIL verification calculations, we look at Clause 11.9. It’s appropriately titled 'Quantification of Random Failures'…putting the focus on 'random' right there in the name.
• 
  S1E45 11.8.4 to 11.8.6 20.01.2026 36นาที

  A device should never remain in bypass indefinitely. Bypass duration must be time-limited, and appropriate compensating measures must be implemented. Listen in for more information and thoughts on this important topic.
• 
  S1E44 11.8.1 to 11.8.3 13.01.2026 1ชม. 1นาที

  The design shall allow for testing of the SIS either end to end OR in segments meaning you could test one piece at a time, but when you do that, you have to be very careful…Tune in as this topic is explored in greater detail, covering Sections 11.8.1 to 11.8.3 in this episode.
• 
  S1E43 11.7.3 05.01.2026 52นาที

  Many users of generic, off-the-shelf PLC logic solvers for Safety Instrumented Systems are surprised to learn that maintenance and engineering interfaces are not permitted to be connected while the process is in operation.Join us as section 11.7.3 is discussed in more detail.
• 
  S1E42 11.7.2 02.12.2025 55นาที

  Bypasses and resets are two standard data elements routinelytransmitted from the BCPS to the SIS, and this communication must be done safely…Listen in for more information on this section.
• 
  S1E41 11.7.1 and 11.7.4 24.11.2025 50นาที

  You can transfer data to and from the Safety Integrated System (SIS), but your design must prevent an outside failure from causing an internal SIS failure.In this episode, we dive into the crucial world of secure data transfer for SIS.
• 
  S1E40 11.6 17.11.2025 36นาที

  Don't let the certificate distract you. Your role as an instrumentation and control engineer requires continued diligence. The work still needs to be done!
• 
  S1E39 11.5.4 through 11.5.6 13.11.2025 1ชม. 9นาที

  Did you know that you can install Programmable Logic Controllers (PLCs) based on prior use without being certified? Sounds easy, right? Think again!While they are exempt from formal certification, we reveal why achieving full compliance with installation and safety requirements is often an extremely difficult, if not impossible, hurdle for engineers. Tune in to learn why relying on prior use might be a compliance nightmare!
• 
  S1E38 11.5.1 through 11.5.3 06.10.2025 1ชม. 1นาที

  The devices you use in your safety instrumented systems DO NOT have to be certified! We're cutting through the noise to give you the facts on what truly matters for functional safety. In this episode we discuss the actual requirements—the principles, standards, and engineering practices—that dictate a device's suitability.
• 
  S1E37 11.4 30.09.2025 58นาที

  You achieve a given SIL target by running a calculation that verifies you achieved the proper probability of failure on demand, yet the standards committee doesn’t trust to do that properly….
