The DT (full) (ID 20006) property must be assigned to a corresponding data field in the data source so that main functions can be generated during the import of devices.

You specify the function definition of the main function to be generated during the import via the assignment of a part. To this purpose you should assign the Part number [x] (ID 20100 x) property to a further data field of the data source. (The "x" after the property number stands for the index here.)

In the process the first function template stored at the part is used to determine the main function. If no function template is stored or the project setting Consider macro when generating devices is activated (command path: File > Settings > Projects > "Project name" > Device > General), the main function is determined via the macro stored at the part.

If no suitable part is found in the parts database or if no suitable main function can be determined from the part due to a missing template / macro during importing, the direct assignment of a function definition is also possible. This can be effected, for example, through the assignment of a data field to the Function definition (ID 20026) property.

If the DT is the same, terminals and plugs are differentiated by means of the Terminal / pin designation (ID 20030) property. For the import of these functions the Terminal / pin designation (ID 20030) property has to be assigned to a data field in addition to the DT (full) (ID 20006) property.

If parts from the parts management are assigned to the terminals and plugs via the Part number [x] (ID 20100 x) property, the function definitions are determined analog to the devices from the parts data. Terminals with parts data are generated as main terminals during the import.

During the import of multi-level terminals you have the possibility to specify the level via a field assignment with the Level (ID 20034) property. In this case the import then recognizes even without the parts data that this is a terminal. Auxiliary terminals for multi-level terminals are generated if values exist for the level in the data source for these terminals, but no part numbers exist.

Both the source and the target of the connection have to exist as a 3D part placement in the project so that non-routed routing connections can be generated during the import of connection data. At least the following properties have to be contained in the field assignment of this import:

• Source (ID 31019)
• Target (ID 310209).

If the DT (full) (ID 20006) property is assigned additionally, the import automatically generates a cable connection.

The "Conductor / wire" function definition is assigned by default to the resulting non-routed routing and cable connections. This function definition can be modified via a further field assignment (for example with the Function definition (ID 20026) property.)

Often, part numbers which are assigned to devices and connections in the external source do not exist in the Eplan parts database. To allow for assignment of parts in such a case nevertheless, other matching properties can be used for the assignment. In addition to the part number the following properties can also be assigned:

• Importing devices: Order number (ID 20919) and / or Type designation of part (ID 20200)
• Importing routing connections: Connection color / number (ID 31004) and / or Connection cross-section / diameter (ID 31002)

For these properties appropriate data fields to which the corresponding Eplan properties can then be assigned have to exist in the external data source.
