The configuration dialog box of objects of the Device definition type consists of several parts (tabs), which contain similar parameters.

To edit individual configuration parameters, press the left mouse button above the corresponding parameter. According to the type of parameter, a value is entered by either typing into the input field or by selecting from the list.
When creating a device definition, it is possible to change the type of device definition with the button 
:
- A Structured Device Definition allows you to edit multiple lines that correspond to device items.
- The Array Device Definition defines an array composed from objects of the Device type - a single line is edited, the Value type is Device and it is necessary to enter the parameters Device type and possibly Mandatory. Other parameters (Start value, Limits, Hysteresis, Status text, Index to transformation palette) are not used.

A unique string of characters within the frame of objects, which meets restrictions for object name in the system.
In addition, there must be no level separator in the name (see conventional device namesthe naming convention of the devices) - by default, it is a dot, alternatively, it can be an underline.
Name is used in references to an item.
Warning: Name can consist of a maximum of 32 characters, capital letters and small letters are not distinguished (e.g. a column name "Hello" and "hello" is are the same).

The possible value types:
| Value type |
|---|
| The entry of start value and its interpretation | |
|---|---|
| Logical | T* - True (word beginning with the character 'T'), otherwise False. |
| Integer | Integer number |
| Real | Real number |
| Absolute time | Time in the form of HH:MI:SS DD-MM-YYYY. |
| Relative time | Time in the form DDD HH:MI:SS.MSS. |
| Text | Text |
| Object | Name of an existing object in the system. |
| Device | Another object of Device type (it is necessary to specify the Device definition for it) |
| Internal item | The name of an existing object in the system that is part of the Device. |
The types from Logic up to Text are common value types and determine the value type of the corresponding column for objects of Structured variable and Database types. The Object type represents either a reference to an object, a structured variable item, a device item, or a value array item. Basically, it is a reference to another object of the D2000 system. Item of a structure, which includes the reference to an object, essentially copies a value of the given object. The Device and Internal Item types represent references to another D2000 object that is understood as part of the device. A naming convention is applied to it, and such an object can only be connected to one Device type object (unlike the Object type, where an object can be connected to multiple Devices and its name does not change).
...
For the value type Object, Device, and Internal item, the attribute Start value defines the object name, to which the item will refer to. Reference to object means, that the corresponding item copies the object value.
...
Using these device definitions, the tree structure Power Plant → Blocks → Generators is modeled (see an example).

The start value of the item in the first row is defined as "Text for start value". The start value in the second row is disabled and the values of both items are undefined after the system start.
Note: The hot key hotkey CTRL+C inserts all configuration parameters into the Clipboard. These can be inserted e.g. into MS Excel.
