The Hidden Cost of Runtime Safety Mutations

This article reveals a fundamental principle in safety-critical engineering: static configurations are non-negotiable. The case study demonstrates how runtime mutations to FSoE safety behaviors created intermittent failures that remained hidden until they mattered most. For engineers working with industrial safety systems like Beckhoff's TwinCAT platform, the lesson is clear: convenience and predictability are in direct conflict on safety systems, and predictability must always win.
