IEC 61346-1 introduced a structured approach based on the "Function-Product-Location" methodology. This tripartite view forced engineers to think of a system not just as a collection of hardware, but as a hierarchy of processes. Under this standard, a single physical object could possess multiple reference designations depending on the aspect being considered. For instance, a variable speed drive could be viewed as a functional unit controlling speed, a product with a specific model number, or a physical object located in a specific cabinet.
