Any process manufacturing company that has not yet launched a cybersecurity program is probably frozen in a frequent difficult position: Where do we start? If your company is trying to break free and make some progress—and maybe you’re the one tasked with doing it—we...
Creating a safe and secure automation process starts with implementing a well-designed basic process control system (BPCS) and safety instrumented system (SIS). Government agencies and industry associations offer guidelines and requirements for how these systems...
In Hydrocarbon Engineering’s Tanks & Terminals Supplement, Emerson’s Helena Hjortsberg looks at all the elements of a comprehensive overfill prevention system in her article, A Coordinated Strategy. Overfilling a tank storing hydrocarbons or other flammable...
In a Paper360 magazine article, "Wireless Sensors Improve Toxic Gas Mitigation in P&P Mills", Emerson’s Forrest Francis explains how workers can avoid nasty surprises. TV shows add drama saying their stories are “ripped from the headlines,” meaning they’re based...
In an Industrial Safety and Security Source article, Considerations in Choosing a Defendable Safety System Architecture, Emerson’s Sergio Diaz and Alexandre Peixoto focus on the basic process control system (BPCS) and safety instrumented system (SIS). They compare various architectures from a cybersecurity perspective.
In an earlier post, How Digital Transformation Can Impact Compliance for Environmental and Safety Regulation, I shared some safety examples. Emerson's Marcio Donnangelo explored specific examples more deeply in his 2020 4C HSE conference presentation, Safety Showers...
A safety instrumented function (SIF) in a safety instrumented system (SIS) contains a sensor, logic solver and final element. All must function properly in the event of a safety demand to take the process into a safe state in coordination with other SIFs. The final...
Bulk liquid storage tanks often contain fluids that are hazardous, flammable and/or explosive. These tanks require not only a control system to control levels but and overfill prevention system (OPS) as layer of protection beyond the control system. This basic process...
The world of functional safety has its own tribal language and acronyms, e.g. safety instrumented systems (SISs), safety instrumented functions (SIFs), logic solvers, final elements (FEs), safety integrity level (SIL), probability of failure on demand (PFD), etc. In a...
The safety valve within a safety instrumented function (SIF) must be tested regularly to help assure proper operation in the event of a safety demand. Operators usually perform an offline full stroke test during a scheduled shutdown because of the impact of this test...
Emerson's Sergio Diaz and Alexandre Peixoto presented Best Practices for a Cybersecure SIS at the 2019 Emerson Exchange conference. Sergio opened that the goal of this presentation is to provide practical information to maintain a more defendable security posture for...
As a product marketing manager for DeltaV safety instrumented systems (SIS), I have been asked a few times why the key switch on the CHARMs Smart Logic Solver (CSLS) does not control the lock state as is common with many safety controllers. The next question is, "Why...
