Section 3

Four different types of SCL files - SCD, CID, IID, and ICD, can be exported from PCM 600.

See

Section 6.1

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.
