Modernization projects have become more important than ever as the benefits of updated control technologies such as better HMIs, advanced process control, better integration with asset management systems, improved alarm management, and more have all transitioned from...
As more and more processing plant personnel begin to work remotely in the wake of cultural changes from the global pandemic and an acceleration in plants’ digital transformation initiatives, there is probably no topic more deserving of attention than cybersecurity....
One of the main concerns from users of process safety systems is how to effectively protect the SIS against unauthorized changes of the safety logic. The traditional protection approach is based on a key switch on the safety PLC; before somebody can alter the safety...
En este episodio el experto en Sistemas de Control y Sistemas Instrumentados de Seguridad, Sergio Díaz, nos comenta sobre las consideraciones más importantes en términos de ciberseguridad en los sistemas de las plantas. Hablamos sobre arquitecturas recomendables,...
Storage tanks containing hazardous materials require safety instrumented systems (SIS) to prevent overfills. Digital technology in the latest level measurement devices used in SIS enables them to be proof-tested remotely, which provides significant advantages. The...
There can be little doubt that COVID-19 has significantly changed the way we all work, and a key example of that change is a massive increase in remote connectivity across industries. In a recent Control Design article examining how COVID has altered the manufacturing...
Traditional safety systems have a centralized architecture, meaning that a large processor unit runs hundreds of safety instrumented functions (SIF). Modern safety systems have a distributed architecture where multiple smaller processor units execute dozens of SIFs....
A plant’s basic process control system (BPCS) and safety instrumented system (SIS) are critical infrastructure for the facility. Many decisions go into selecting these systems, and one of the most important is selecting the right architecture—a decision that will...
Safety and risk reduction are both high priorities for operators in the process industry. Not only is it critical to maintain the health and safety of personnel, but past industrial incidents have caused extensive damage to nearby areas, causing harm to residents and...
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...
Measurement instrumentation has traditionally been used by process manufacturers to control their processes safely and reliably. This instrumentation may not be enough to operate the process as efficiently as possible. In a recent comment to one of my earlier posts,...
Emerson's Chris Womack highlights a liquefied petroleum gas (LPG) project in Mexico in today's guest post. In liquid petroleum gas terminals featuring partial automation, several systems control the plant's filling racks, custody transfer areas, and safety systems....
