    Safety Instrumented Systems Blog: Non-contacting Radar for Automatic Tank Gauging and Overfill Prevention Systems

    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 control system (BPCS) is commonly referred to as an automatic tank gauging (ATG) system and the OPS is the safety instrumented system (SIS). A Fluid...

    Safety Instrumented Systems Blog: Understanding Functional Safety Concepts and Final Element Suitability

    Riyaz Ali 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 Hydrocarbon Engineering article, Keep in the Safety Loop , Emerson’s Riyaz Ali does an excellent job of defining and demystifying these phrases...

    DeltaV Blog: Migrating Legacy Control Systems and PLCs with FlexConnect Solutions

    Scott Ross Now, with these control systems being more than 30+ years old, most of these legacy systems have been placed in to end of life or retired lifecycle status which means no further factory support is available. I caught up with Emerson’s Scott Ross about the choices that must be considered moving forward. Manufacturers and producers face options whether to modernize to a newer family of distributed control...

    DeltaV Blog: Migrating Legacy PLC-5s to DeltaV

    Way back in the mid-1980’s, when I was a newly-minted engineer working oil & gas production projects offshore in the Gulf of Mexico, a new series of PLCs came on the scene to replace the Allen-Bradley PLC-2’s we had been using. They were the PLC-5 series. Javier DeLuna Now, more than 30 years old, the CPUs used in these PLCs were placed into end of life status which meant no further factory support for the CPUs as...

    Safety Instrumented Systems Blog: Approaches to Partial Stroke Testing Safety Valves

    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 on the process. But when a SIF (a.k.a. safety loop) requires more frequent testing, users can perform a partial stroke test (PST) , per the global IEC 61511...

    Safety Instrumented Systems Blog: Security for Safety System Logic Solvers-Physical Key Switches and Software Locks

    Sergio Diaz Author: Sergio Diaz 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. DeltaV CHARMs Smart Logic Solver (CSLS) The next question is, “Why does the user still need to lock the CSLS via software?” The reason is...

    Ovation Blog: Suppressing Plant Alarms

    Ben Poskie Since the early days of distributed control systems, much work has been done to improve alarm management and prevent alarms from flooding operators to prevent them from properly diagnosing and correcting abnormal situations. The ANSI/ISA 18.2 alarm management standard began development back in 2003 and built off of the work of other alarm management initiatives. It published as ANSI/ISA-18.2-2009 Management...
