1 Scope
Replace the existing text of the first paragraph of the scope with the following new text:
This part of IEC 61850 applies to projects associated with processes near automation systems
of power utilities (UAS, utility automation system), such as substation automation systems
(SAS). It defines the system and project management for UAS with communication between
intelligent electronic devices (IEDs) in the substation respective plant and the related system
requirements.
2 Normative references
Replace the existing reference to IEC 61850-6 with the following new reference:
IEC 61850-6, Communication networks and systems for power utility automation – Part 6: Con-
figuration description language for communication in power utility automation systems related
to IEDs
Delete the references to IEC 81346-1 and IEC 81346-2.
4 Abbreviations
Add the following new abbreviations:
icd IED capability description file
ICT IED configuration tool
iid instantiated IED description file
scd substation configuration description file
SCT system configuration tool
sed system exchange description file
ssd system specification description file
5 Engineering requirements
5.3.4 IED configuration tool
Replace the existing text of the fifth paragraph of 5.3.4 with the following new text:
The tool’s data input module supports the interactive input of parameters as well as the import
of the system description as created by means of the system configuration tool. The structure
of input data should be technically oriented towards the process architecture, i.e. structured
according to the hierarchical approach to substation, voltage level, bay, equipment and function.
Replace the existing text of the first bullet with the following new text:
– process (e.g. substation or line) identification;
Add the following new subclause after 5.3.5:
5.3.6 Engineering tool workflow
5.3.6.1 From system specification to project description
Typical use case: one centralised SCT working with several ICT (see Figure 12).

Figure 12 – Engineering workflow steps from system to project
Step 1: System Specification Tool (SST) creates an ssd file according to IEC 61850-6.
Step 2a: IED Configurator Tool (ICT) creates an icd file according to IEC 61850-6.
Step 2b: ICT creates an iid file according to part 6.
Step 3: System Configuration Tool (SCT) creates an scd file, using previous files: ssd, icd
and/or iid.
Step 4: This SCD is used by an ICT to finalize configuration and publish an cid file to its related
IED (configuration of dataflow).
The fourth step is the last except if the scd contents requires modifications from the
ICT, which shall be transferred to the SCT in order to publish a updated scd. Then it
is replaced by step 5 hereafter.
Step 5: ICT updates the IED description based on the further IED configuration needs and on
system configuration needs provided by SCT in step 3. The ICT exports to the SCT
the updated configuration description via the iid file.
Step 6: SCT publishes a updated scd file taking into account information described by previous
IID.
Step 7: ICT publishes the updated cid file to send to the IED, using the scd published on step 6.
5.3.6.2 Change of system tool
Use case: considering an SCT A has to be replaced by an SCT B. The context is transferred
with an scd exported from the SCT A.
The creation of the project with SCT A is similar to the previous use case and is
assumed to be done before the replacement of SCT A as classical project engineer-
ing as shown in Figure 13.
NOTE Changing an SCT is always done with the purpose of updating / upgrading the system configuration with
features that previous SCT does not support.

Figure 13 – Change of system tool first stage
Step 1: System Specification Tool (SST) creates an ssd.
Step 2a: IED Configurator Tool (ICT) creates an icd.
Step 2b: ICT creates an iid as a first instantiation.
Step 3: SCT creates an scd, using previous files: ssd, icd and iid.
Step 4: ICTs create iid using the scd issued on step 3.
Step 5: SCT publishes a new scd taking into account information described by previous iid.
Hereafter the second stage, the SCT B uses the scd provided by the SCT A as shown in
Figure 14.
Figure 14 – Change of system tool second stage
Step 6: SCD to be transferred by SCT A to SCT B. Even if that does not appear on the
scheme, it is strongly recommended to also transfer the latest version of all icd files.
Step 7: SCT B updates the scd, using previous scd created by SCT A (previous step).
Step 8: ICTs create iid using the scd issued on step 7.
Step 9: SCT publishes a new scd.

Step 10: ICTs create cid using the scd previously created.
5.3.6.3 Interaction between projects
Use case: considering 2 different configuration projects managed by 2 SCT A and B (The
2 configuration projects may cover one or multiple UAS). One IED (e.g. IED 2)
regards both projects. The cid intended to the IED 2 shall take into account both
contexts. The final step is the publishing of the cid.
Hereafter, the first stage consists of the publishing of the SCD, as shown in Figure 15.

Figure 15 – interaction between projects, first stage
Step 1: System Specification Tool (SST) creates an ssd.
Step 2a: IED 1 Configurator Tool creates an icd.
Step 2b: IED 2 Configuration Tool creates an iid as a first instantiation.
Step 3: SCT creates an SCD 1+2, describing both IED 1 and IED 2 and using previous files:
ssd, icd and iid.
Step 4: ICTs create iid using the scd issued on step 3.
Step 5: SCT publishes a new scd 1+2 taking into account information described by previous
IID.
Hereafter, the second stage consists in using part of the scd 1+2, that is involved in the com-
munication of a second project, as shown in Figure 16.

Figure 16 – interaction between projects, second stage
Step 6: SCT A creates an sed 2r, which gives only required information on the IED 2 needed
for the engineering of the second project. (therefore “reduced IED 2”)
Step 7: SCT B creates an scd 3+4+2r’, using the sed 2r created by sct A (previous step) and
taking into account its own context.
Step 8: ICTs create iid using the scd 3+4+2r’.
Step 9: SCT B creates a new sed 2r’ taking into account IED 2 in the SCT B context.
Step 10: SCT A creates a new scd 1+2’ using the sed 2r’ to integrate dataflow modifications of
IED 2 coming from the sct B.
Step 11: ICTs create cid using the scd previou
