Structuring of Projects in Accordance with EN 81346

The extended reference identification allows for working with a device structure in compliance with the EN 81346 standard. The device structure can be determined, according to the standard EN 81346, by the structuring criteria function, location, and product aspect. An aspect describes in which way an object is seen. Thus the product aspect clearly documents which physical parts make up a plant, a construction unit, etc. In EPLAN, devices are managed by functional categories (such as, e.g., "Coils and contacts", "Signal devices", etc.) and structured by means of identifier blocks. The functional aspect is accounted for by the higher-level function (preceding sign "="), the location aspect by the mounting location (preceding sign "+"), and the product aspect by the product aspect identifier (preceding sign "-"). The product aspect is the identifier block for the device.

If the Extended reference identification check box is activated in the Structure tab in the project properties, the behavior with regard to the entry and reporting of the DT is changed:

Tip:

If you use the extended reference identification, the page structure is not used for the structuring of the devices. To nevertheless use various aspects (functional aspect (=), location aspect (+), product aspect (-)) as structure elements for the devices we recommend placing a structure box around the complete page. Then the structure identifiers of the box are inherited to the devices and these structures can also be adapted when pages are copied.
