A complete reference designation consists of a prefix indicating the aspect, followed by a combination of letters and numbers representing the class and specific item. For example, a designation might look like this: =A1-K2 = indicates a function-oriented aspect.

Example: -K1 represents a specific physical relay or contactor. Focuses on where the object is physically situated. iec 61346-1 pdf

Engineering firms, automation professionals, and CAD designers frequently look for copies of the original standard for several reasons:
