Blog Entry: Back to Basics 15 - Architectural Constraints
Architectural constraints are limitations that are imposed on the hardware selected to implement a safety-instrumented function, regardless of the performance calculated for a subsystem. Architectural constraints are specified (in) according to the required of the subsystem, type of components used, and of the subsystem’s components. (Type A components are simple…

White Paper: Strategic Proof Testing
Safety Instrumented Systems (SIS) are designed to provide automatic protection functions. A typical design includes a sensor to detect the potentially dangerous condition, a safety PLC and a remote actuated valve capable of taking action to prevent an accident. In a well designed chemical plant the potentially dangerous conditions occur…
Recorded Webinars: Management of Change For Alarm Rationalization
Management of change (MOC) is recognized as a crucial activity in OSHA’s process safety management regulation. It also a stage in the ISA-18.2 / IEC 62682 alarm management lifecycle. In this webinar, we will explore how
MOC is conducted in the context of Alarm Management. We will look at the basic flow of MOC and consider situations where improper changes to the alarm system can create a hazardous situation. Finally the webinar will look at how having a built-for-purpose tool like SILAlarm can support implementation of MOC associated with rationalization
Recorded Webinars: Proof Test Planning with exSILentia®
A key parameter to achieving your target Safety Integrity Level (SIL) is defining the proof test strategy for the devices in your Safety Instrumented Functions (SIFs). Proof tests are performed on SIF equipment periodically to reveal any dangerous failures that could prevent the SIF from returning the process to the safe state. In the conceptual design, the frequency and effectiveness of the proof tests can dramatically affect the calculated results of your SIL Verification. This webinar reviews the impact of the proof test strategy on your achieved SIL, and shows how to specify a proof test procedure to ensure testing is carried out as intended, ensuring the integrity of your Safety Instrumented System (SIS).
Recorded Webinars: IEC61511 and Cybersecurity: Are Your Safety & Control Systems Really Protected?
When it comes to process safety, most companies will focus on the functional safety lifecycle and compliance with IEC61511. However, with the advent of the industrial internet of things (IIOT) and the growing use of wireless technologies, it is becoming more important to consider cybersecurity and the consequences of control and safety systems being compromised due to a cyber-related incident. Recent ransomware attacks such as Wannacry and NotPetya have again highlighted the need to be more vigilant when it comes to protecting control systems and OT infrastructure. The number of Malware attacks has risen exponentially over the past 10 years but still companies have been slow to react.
The update to IEC61511 in 2016 to include a cybersecurity assessment of an SIS, means companies can no longer procrastinate and/or delay reviewing any SIS for cyber vulnerabilities. Since the standards for functional safety (IEC61511) and cybersecurity (IEC62443) both follow a similar 3 phase lifecycle, it makes sense to consider these two together, when it comes to process safety. This means being just as vigilant with cybersecurity, as with functional safety. As such an integrated lifecycle approach will help in mitigating risk.
This webinar highlights the risks and need to address cybersecurity per the IEC61511 standard and the reasons why. Ignorance may be bliss until your system, network and plant becomes compromised. Then it’s a whole other story.

Recorded Webinars: What Does “… failures which are the responsibility of the manufacturer were examined” Mean ?
What does “… failures which are the responsibility of the manufacturer were examined” mean with failure rate data?
There are a few assumptions that make a large difference in failure rate data. One of these is the definition of a “failure.” On any valid certificate, information is given to help the user understand the data. It is critically important to anyone using the data for SIL verification. This webinar shows examples of failure rate data provided by certification bodies and explains qualifying statements provided on the certificates.

Blog Entry: Back to Basics 14 - Systematic Capability
Systematic Capability is achieved when the equipment used to implement any safety function achieves two goals: the design process has used procedures intended to prevent systematic design errors (fault avoidance) and the design has systematic design control mechanisms such as a diagnostic for incorrect software execution (fault control). The rigor…
Recorded Webinars: Why People Dangerously Ignore Motor Controllers in a SIF
In the process industry, Motor controllers are often used in safety instrumented functions to de-energize pumps, fans, and rotating equipment. These devices are often ignored in SIF design verification because IEC 61508 certified devices are hard to find and failure rate data is often not available. This webinar explains how to fill that void by informing where to get failure rate data for these important devices and gives examples of using both a certified device with actual FMEDA data and generic failure data.
