CDV61850-6©1EC:2002 -4- 57WG10 INTRODUCTION Part 6 of this standard specifies a description language for configurations of electrical sub- station IEDs.This language is called Substation Configuration description Language(SCL).It is used to describe IED configurations and communication systems according to parts 5 and 7-x of this standard.It allows the formal description of the relations between the substation automation system and the substation (switchyard).At the application level the switchyard topology itself and the relation of the switchyard structure to the SAS functions (logical nodes)configured on the IEDs can be described. SCL allows the description of an IED configuration to be passed to a communication and ap- plication system engineering tool,and to pass back the whole system configuration descrip- tion to the IED configuration tool in a compatible way.Its main purpose is to allow the inter- operable exchange of communication system configuration data between an IED configura- tion tool and a system configuration tool of different manufacturers. The parts 8-x and 9-x of this standard,which are concerned with mappings of parts 7-x to specific communication stacks,may extend these definitions according to their need with ad- ditional parts,or just by restrictions on the way the values of objects have to be used.

The resulting object model however could also be the base for other engineering tasks,either directly,or with some additions.Therefore,and because of additional needs of SCSMs,this standard considers the language as defined here as the core model,and defines,how exten- sions of this core model for SCSMs as well as other (engineering)purposes can be done in a standardised way.
