The standard introduces a hierarchical structure for labeling. Instead of a flat list of tags (like "Motor 1"), it allows for nested structures.
As the newly appointed automation engineer at a modern manufacturing plant, Emma's task was to oversee the implementation of a new industrial automation and control system (IACS). Her goal was to ensure seamless communication between the various control devices, sensors, and actuators on the production line.
-K1 typically represents a specific relay or contactor product. 3. The Location-Oriented Aspect (Where the object is)
This aspect looks at the physical components chosen to execute a function. It focuses on the actual hardware, modules, or parts lists. - (Minus sign) iec 61346-1 pdf
The official source for the IEC 61346-1 and updated IEC 81346-1 standards.
Modern Computer-Aided Engineering (CAE) tools—like EPLAN, AutoCAD Electrical, and COMOS—rely on these structured databases to automate documentation generation. Evolution: From IEC 61346 to IEC 81346
If you are working with an older codebase, search their archives for withdrawn or historical versions of the document. Her goal was to ensure seamless communication between
To create a flawless reference designation, the standard views each object through three distinct "aspects" or lenses: 1. The Function-Oriented Aspect (Prefix: = )
In 2009, IEC 61346-1 was merged into . The changes are subtle but critical:
Maintenance technicians can read a code on a touchscreen error log and immediately know the exact cabinet, row, and rail where the faulty component resides. The Location-Oriented Aspect (Where the object is) This
The standard recognizes that a single physical object has multiple "aspects" (views). For example, a motor:
Engineering firms, automation professionals, and CAD designers frequently look for copies of the original standard for several reasons:
A core feature defined in the standard is the use of single upper-case letters to identify the aspect of the object being referenced. This is the breakdown engineers look for most often in the PDF:
To help you apply these principles to your current projects, let me know:
