There are certain properties assigned to every object in Eplan. Objects are divided into different object classes, e.g. "Project", "Form", "Symbol", "Function", "Part reference", etc. The properties are identified by property numbers (IDs); the same number may occur for multiple object classes. For instance, the property "Function definition description" has the number <20117> assigned to it in the object classes "Function", "Symbol", and "Connection".
The following information is displayed in the overview of the Eplan properties:
|
Entry |
Meaning |
|---|---|
|
ID |
The property number (or ID) uniquely identifies the property. This number is evaluated internally by Eplan. In the user settings, you can specify whether the property number is displayed in the program user interface. |
|
Designation |
The name of the property, which is displayed in the program's user interface. |
|
Object classes |
Specifies the objects for which the property is available. |
|
Description |
An explanatory text is displayed here for most of the properties. |
|
Category |
For display in the program, the properties are divided into different categories, that is, in groups of properties which can be displayed independently of one another. |
|
Field type |
The field type determines the permissible characters and the format provided for the property. Possible field types are, for example, "Boolean (True / False)", "Decimal number", "Multilingual text", "Value with unit". |
|
Unit group |
All property definitions of the field type "Value with unit" dispose of additional information for the definition of the concrete unit group (such as "Length" or "Pressure"). If a unit group is defined for a property of the field type "Value with unit" and a value without unit is entered for this property, the corresponding default SI unit is used for the value (for example during a conversion). |
|
Index (max.) |
Specifies whether an index is possible for the property; in this case, the maximum possible index value is displayed. In the selection dialog a The index can be used to enable multiple display of a property, such as the display of multiple part numbers which are assigned to the same device. For the property "Part number" <20100>, the index "[3]" gives the third part number. If a property has an index, then the index value "[0]" normally means that all values of the property are output; for example, all assigned part numbers. In the tree structure of the selection dialog, this corresponds to the level with the |
|
R/O |
Specifies whether the property is read-only. "Yes" indicates a write-protected property; "no" means that you can edit the property. Depending on the field type of the property, you can then manually enter the values, select them from a list, or check a check box. |
|
API define |
The name under which the property is addressed through the API interface. |
sign is shown next to property. If you click on that symbol, the list of possible indexed properties is expanded in the tree view, and you can select the desired property.
Notes:
With the exception of the following situations, the field type "Value with unit" behaves like a "monolingual text".
- If an Eplan parts database is set for the parts management and a value with unit is specified as the filter criterion for a property during filtering (for example "1 kV"), the properties for which this value was specified with a different unit (for example "1000 V") are also displayed as search results.
- For values with decimal places, the decimal separators that are set for the operating system are used during the display of the properties in the property dialogs, in the graphical editor or in the parts management and not the entered decimal separators ("," or ".").
- If a value is specified without a unit for a property of the field type "Value with unit" and a unit group is defined for this property, the corresponding default SI unit is used for the value (for example during conversion).
