CONFIGURATION
SCL Format• Defined in IEC 61850 Part 6
• Four different file types
• System Specification Description (SSD) – power system functions
• Substation Configuration Description (SCD) – complete substation
• IED Capabil ity Descript ion (ICD) – the data reported by a type of IED
• Configured IED Descr ipt ion(CID) – the configuration of a specific IED
• Five sections per file• Header – Identifies the configuration file
• Substation – Identifies electrical connections and functions
• Communications – Identifies addresses and subnetworks
• IED – Identifies functions and configuration of devices
• Data Type Templates – Used to build the other sections

CONFIGURATION
IED Capability Description
• The IED capabil ity description file (.icd) describes the capabilities and(optionally) the preconfigured data model of the IED
– logical devices, logical nodes, logical node types – data sets
– control blocks – not populated
• Think of it as an “IED Template”

CID
File
IED Configuration Tool
SCD
File
• The configured IED descript ion file (.cid) describes an instantiated IED with
all configuration parameters relevant for that IED
• Created by the IED configuration tool from the .scd file
• Includes the device-specific configuration data
• Use of the .cid file to configure the IED is optional.
• As an alternate solution, a vendor specific file may be used
