Substation Configuration description
Language (SCL)
SEMOD129808-4 v9
Four different types of SCL files - SCD, CID, IID, and ICD, can be exported from PCM 600.
See
The SCL language is based on XML. However, detailed knowledge of the XML contents is not
needed.
The SCL XML file (ICD/SCD/CID/IID/ SED and SSD) contains five sections, which are specified in
IEC 61850–6 clause 9.
•
Header
•
Substation section describes the functional structure and its relation to primary devices.
•
Communication section describes the connection between the IED access points to the
respective subnetwork. and includes also the properties (addresses) of the access points.
•
IED section contains a description of the supported communication services, the access point(s)
and the IEDs logical devices, logical nodes and their attributes.
•
Data type template section contains a declaration of all types used in the SCL file, logical nodes
type, DO types, attributes and enums.
The system structure is defined by the organization of the plant structure in PCM600. The signal
engineering and the signal routing are IET600 tasks, signal engineering regarding DS, rcb,gcb,
GOOSE subscribers can be done also in PCM600. The IED needs to be configured with PCM600
before the system is configured with IET600.
The SCL engineering must be done in an SCL engineering tool. The data sets and the control blocks
are logically defined as part of the logical nodes (see IEC 61850–7–2 clause 9). The IED also needs
a correctly configured communication section for GOOSE engineering, which can be done in IET600
or PCM600.
The data type templates section provides the correct content description of each logical node type to
all tools and users (clients) of the information. Each IED and vendor may have their own logical node
type definitions included in the data type template section together with all other logical node types
based on the standard.
