A centrifugal pump in the chemical treatment area: =F02+MP01-M01 = "Motor 1 of function F02 located in motor pump building 1."
This aspect treats the object as a physical piece of trade hardware or software. It focuses on the component itself as delivered by a manufacturer. A specific relay, circuit breaker, or motor. Prefix: The minus sign ( - ). Combining Aspects
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. iec 61346-1 pdf
The "depth" of this standard lies in its . You can zoom into any part of a system—from a massive power plant down to a single fuse—and give it a unique "address" that remains clear across all technical disciplines.
It is important to note that has been largely superseded by the newer IEC 81346 series . While the core principles remain similar, IEC 81346 provides a more flexible, modern structure designed for complex, highly automated environments. A centrifugal pump in the chemical treatment area:
Technicians can trace faults faster when terminal blocks, wires, and schematics share a logical, predictable naming convention.
This aspect focuses on what the object is doing or what its purpose is within the system, completely independent of its physical form or location. Prefix: The minus sign ( - )
| 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) |

It moved industry away from confusing, proprietary naming conventions toward a globally interoperable standard. Its "aspect" system allowed different teams (e.g., electrical vs. mechanical) to refer to the same system using a common language.
