Iec 61346-1 Pdf [portable]
The standard covers the general requirements for documentation and graphical symbols used in electrotechnology, including:
| Aspect | Prefix | Meaning | Example | | :--- | :--- | :--- | :--- | | | = | What the object does in the process | =F1 (Feeding system) | | Product Aspect | - | What type of component it is | -K1 (Contactor/Relay) | | Location Aspect | + | Where the object is physically located | +C01 (Cabinet 1) |
This standard defines how to structure technical systems and create (unique identifiers for objects).
Where is it? (e.g., +L1 for a specific cabinet or room). The "Deep Story": Why it matters iec 61346-1 pdf
No, technically it is "withdrawn" but remains widely used in legacy documentation. The active standard is .
Therefore, if you are maintaining or retrofitting an older facility, referencing the original IEC 61346-1 PDF is necessary. However, for all greenfield projects and modern designs, you should refer to the and IEC 81346-2 PDF . Where to Safely and Legally Obtain the Document
Most software tools (AutoCAD Electrical, EPLAN, COMOS) have implemented the letter codes (e.g., -K for relay, -M for motor). But very few have implemented the relationship logic . The "Deep Story": Why it matters No, technically
Create a master table linking each reference designation to:
This aspect focuses on the actual physical product or hardware component used to fulfill a function. A specific relay, motor, or sensor model. Identifier: Marked with a minus sign or hyphen ( - ). How Reference Designations Work
Assemblies and sub-assemblies (e.g., amplifiers, laser units) However, for all greenfield projects and modern designs,
The standard uses specific prefix signs to distinguish these three distinct viewpoints: 1. The Function-Oriented Aspect (Prefix: = )
The standard defines how to organize a system based on three main perspectives: Function Aspect (=): What the object does. Product Aspect (-): How the object is constructed or what it is made of. Location Aspect (+): Where the object is physically located. Hierarchical Structuring:
