A device should never remain in bypass indefinitely. Bypassduration must be time-limited, and appropriate compensating measures must be implemented.

Listen in for more information and thoughts on this importanttopic.

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.

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.

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.

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.

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!

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!

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.

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….

How should the safety instrumented system respond to adetected failure?  Well, it will respond however you want it to respond…
