Data object type child DA

Add new DA

You can use OpenSCD to add new DAs to an existing DOType.

1. Navigate to the DOType you want to edit and open the Edit DAType wizard.
2. Click on DATA ATTRIBUTE button in the middle of the wizard.

Settings:

1. name*: If you choose to have a BDA from IEC 61850 namespace consult IEC 61850‑7‑4. Otherwise make sure to start with an lower case latter [a-z]
2. desc: user-defined description field
3. bType*: The attributes basic type. If Enum or Struct the type field may not be empty.
4. type*: Type is defined as string in the SCL but is a selector in OpenSCD. If bType is Struct the selector shows all DAType - id's in the project. Without existing DAType in the project you cannot create a BDA. If bType is Enum the selector shows all EnumType - id's in the project.
5. sAddr: user-defined string to describe a short address
6. valKind: Might be missing and if not must be either true or false.
7. valImport: Might be missing and if not must be either true or false.
8. Val: Value element that allow you to pre-define the value offline. This can be added to any data attribute (DA or BDA).
9. dchg: data update acc. IEC 61850-7-3 for this particular data attribute.
10. qchg: quality update is true for all DA of name a else is empty
11. dupd: data update acc. to IEC 61850-7-3
12. fc: functional constraint acc. IEC 61850-7-3 for this particular data attribute.

NOTE: Val definition does not make sense for all function constraints (FC). E.g status type data attribute as stVal is not very useful. For other data attributes it perfectly makes sense to pre-define the value. E.g. the ctlModel

NOTE: Since Edition 2 you cannot design your own CDC and must use for t a user-defined data object a CDC from IEC 61850-7-3. This means that the data attributes are defined. Please check the tables to set the attributes dchg, qchg, dupd and fc

Edit DA

You can use OpenSCD to manipulate existing DA.

1. Navigate to DOType list in template editor
2. Click on DOType that contains the DA you want to edit
3. Click on child DA you want to edit

Settings:

The settings are the same a in the Add DA wizard with the difference that there is a remove button.

Example:

<DA name="ctlModel" bType="Enum" fc="CF" type="CtlModelKind">
    <Val>sbo-with-enhanced-security</Val>
</DA>

 

Remove DO

1. Open Edit DA wizard
2. Click on Remove button

WARNING: OpenSCD does not check for validity before removal so be careful!
