  • Addressing Common Misconceptions in Safety System Configuration

    Jim Cahill
    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. Distributed safety systems offer many cost and maintenance benefits, but some users worry they’re harder to configure than a centralized safety system. I…
