Configuration Dialog Box (D2000/Structures and Databases/Structure Definition)
Structure definition - configuration dialog box
Editing of all objects in the process D2000 CNF is being performed in the configuration dialog box, a specific part of which is common for all editable objects and another part depends on the type of edited object.
Configuration dialog box of objects of Structure definition type consists of several parts (tabs), which contain similar parameters.

General properties
Description
A text string describing the structure definition. Maximum: 128 characters.
Possibility to use the Dictionary (to open press CTRL+L).
Structure
Individual items (columns) of the structure are defined in the list, where each row of the list corresponds to one item of the structure and displays all configuration parameters.
To modify the number of items in the list use the following buttons:
 | - inserts a row above current one |
| - adds a row to the end (last one) |
| - deletes current row |
| - inserts a copy of current row above the current row |
| - adds a copy of current row to the end (last one) |
During editing of a used structure definition, it is not possible to decrease the number of columns..
To edit individual configuration parameters, press the left mouse button above corresponding parameter. According to the type of parameter, a value is entered by either typing into the input field or selecting from the list.
Name
Unique string of characters within the frame of objects, which meets restrictions for object name in the system Name is used in references to an item.
Warning: Name can consists of maximum 32 characters, capital letters and small letters are not distinguished (e.g. a column name "Hello" and "hello" is the same).
Description
Arbitrary text string. Maximum: 50 characters.
Value type
The possible value types:
Value type | 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 existing object in the system. |
The types from Logic up to Text are common value types and determine the value type of corresponding column for objects of Structured variable and Database types. The type Object represents either a reference to an object, or a structured variable item or a value array item. Basically, it is a reference to other object of D2000 system. Item of a structure, which includes the reference to an object, essentially copies a value of the given object.
Start value **
Text parameter, which determines the start value of the item after the system start. Start value is
expressed by a text and is converted to corresponding type during the system start. Unsuccessful
conversion is expressed by invalid value.
For example: the column type is Integer an Start value is "4", the value of
corresponding columns of objects of Structured variable type is to be 4 (if the attribute is
not redefined) after the system start.
For the value type Object, the attribute Start value defines the object name, which
items will refer to. Reference to object means, that corresponding item copies the object
value.
Note: The parameter can be disabled*.
Limits and hysteresis **
Limits (VHL, HL, LL VLL) for setting the limit attributes and hysteresis.
Note: The parameters can be disabled*.
Status text
Connected object of Status text type determines the way of displaying values of the column. To disable used Status text enter empty object name.
