Overview of SCL Navigator

SCL Navigator is a Windows™ application for creating, viewing, editing, and verifying IEC 61850 System Configuration Language (SCL) files with an intelligent editor. 

 The tool makes it easier to work with SCL files:

  • View SCL files with simplified XML view or as an interpreted data model
  • Create IED Capability Description (.ICD) files with standard IEC 61850 logical nodes and data objects (Ed. 1 or 2)
  • Manage data templates with the option to edit, reuse, or clean templates
  • Verify SCL Files with results that are highlighted in the editor



View Files as XML or Data Model

SCL files can be viewed and edited with an intelligent, simplified XML editor. This view shows important XML tags that are needed in different parts of the data model.

There is also the option to see the SCL file as an interpreted data model. This allows SCL files to be viewed and edited on a line by line basis (with the XML view) but also verified by viewing how the tool builds the data model.



Create a Clean Data Model

Data models for an IED Capability Description (ICD) template can be created with standard IEC 61850 data objects. Logical nodes & data objects from -7-3, -7-4, -7-410 (Hydro), -7-420 (DER), -90-7 (DER), and IEC 61400-25 (Wind) can be added to the data model. Mandatory or optional objects can be added according to the IEC 61850 standard (both Edition 1 & 2).

The tool manages the Data Type Template section with the option to edit data templates, reuse templates, or clean the templates section to remove unused sections. This allows you to build an efficient data model that does not lead to oversized SCL files during the engineering process.



Verify SCL Files

SCL verification is built in to help make SCL files more inter-operable. SCL verify identifies missing parameters and non-compliant SCL. The tool also checks the data model against the standard and verifies that data type template references can be resolved. It also verifies that control blocks, external references, and datasets can be resolved.

Warnings and errors are displayed to distinguish high priority issues. The location of the warning or error is highlighted in the XML view for convenient troubleshooting.
