Focused on what the object does (e.g., "=K1" for a specific control function). -
The most significant innovation of IEC 61346-1 is the "three-aspect" philosophy. An object can be identified based on different viewpoints, each represented by a specific prefix: Description = iec 61346-1 pdf
Engineers and documentation specialists frequently search for the "IEC 61346-1 PDF" document for several practical reasons:
By splitting data into these independent paths, a single physical component can be easily traced across different disciplines. For instance, a software programmer cares about the function code ( = ), a procurement officer needs the physical product code ( - ), and a field technician depends on the physical location identifier ( + ). What (like EPLAN or AutoCAD) are you using
: By combining these aspects with prefix signs (like = for function or + for location), engineers create unique identifiers (e.g., =G1+L1-K1 ) that tell you exactly what a part does and where it is. Evolution to IEC 81346
Focuses on how the object is constructed or what physical product serves the purpose. An object can be identified based on different
solves this by introducing object-oriented structuring . The standard provides rules for breaking down any technical system into manageable, reusable objects and assigning them reference designations that remain consistent across all disciplines (mechanical, electrical, software, etc.).
Industrial machinery, power plants, and manufacturing facilities have lifespans spanning 20, 30, or even 40 years. Millions of engineering blueprints drafted in the late 1990s and 2000s strictly follow IEC 61346-1.
In the early days of industrial plants, every discipline had its own language. An electrical engineer saw a "pump" as a motor load; a mechanical engineer saw it as a flow device; a maintenance worker saw it as a physical object bolted to the floor in "Room 402." This created massive confusion during construction and repairs because one "thing" had three different names in three different sets of documents. The Solution: The "Aspect" System
