CHAPTER 3: IEC 61850 COMMUNICATION
When applying such a template file at the system configuration stage, the configurator is used to put in the ExtRef
element a reference to the signal source appropriate to the description in desc element attribute. The configurator is also
used to configure a GOOSE control block and dataset in the sending IED to publish the signal, and to put in the ExtRef
element a reference to this control block.
3.10.8.3 SCL file example
Were the example IED of clause 7 outlined earlier to support intermediate objects according to this annex, its ICD file then
defines each of them with the lines similar to the following in one of its LN or LN0 elements, in this example, in GGIO3. Note
that in this example only two such are defined; typically there are many more. The changes from the files are shown in red.
<LN lnClass="GGIO" prefix="ConOut" lnType="GGIO"
<DOI name="InRef1" desc="Contact Output Control">
<DAI name="setSrcRef"><Val></Val></DAI>
<DAI name="setSrcCB"><Val></Val></DAI>
</DOI>
</LN>
<LN lnClass="GGIO" prefix="" lnType="ExtRefs"
<Inputs>
<ExtRef desc="unassigned GOOSE Boolean input #1" intAddr="Ind1"/>
<ExtRef desc="unassigned GOOSE Analog input #1" intAddr="AnIn1"/>
</Inputs>
</LN>
<LNodeType id="ExtRefs" lnClass="GGIO">
<DO name="Ind1" type="SPS" />
<DO name="AnIn1" type="MV" />
</LNodeType>
To specify that the IED receives an unspecified "Overcurrent alarm" GOOSE signal and that this signal drives a contact
output, the configurator copies the previous code to the template file for the subscribing IED modified as follows.
<LN lnClass="GGIO" prefix="ConOut" lnType="GGIO"
<DOI name="InRef1" desc="Contact Output Control">
<DAI name="setSrcRef"><Val>TEMPLATELD1/GGIO3.Ind1.stVal</Val></DAI>
<DAI name="setSrcCB"><Val></Val></DAI>
</DOI>
<LN lnClass="GGIO" prefix="" lnType="ExtRefs"
<Inputs>
<ExtRef desc="Overcurrent
<ExtRef desc="unassigned GOOSE Analog input #1" intAddr="AnIn1"/>
</Inputs>
</LN>
The CID for the example IED of clause 7 earlier then has these lines further modified as follows.
<LN lnClass="GGIO" prefix="ConOut" lnType="GGIO"
<DOI name="InRef1" desc="Contact Output Control">
<DAI name="setSrcRef"><Val>E1Q2BP1LD1/GGIO3.Ind1.stVal</Val></DAI>
<DAI name="setSrcCB"><Val></Val></DAI>
</DOI>
<LN lnClass="GGIO" prefix="" lnType="ExtRefs"
<Inputs>
<ExtRef desc="Overcurrent alarm" intAddr="Ind1"
iedName="E1Q1BP1" ldInst="LD1" prefix="" lnClass="PIOC" lnInst="1" doName="Op" daName="general"
srcLDInst="LD1" srcPrefix="" srcLNClass="LLN0" srcCBName="GoCB1"/>
<ExtRef desc="unassigned GOOSE Analog input #1" intAddr="AnIn1"/>
</Inputs>
</LN>
