Description
Today we have the MICS, the NSD, the ICD.
Which document/file can a user consult to learn about the model implemented in a device?
The MICS only states the manufacturer specific extensions to the standard model. The ‘normal’ model is not exposed.
The NSD states in a machine readable format the manufacturer specific extensions to the standard model. The ‘normal’ model is not exposed.
The ICD states the complete model of a device. Problem: you need to get that ICD.
ICDs can be of master-model type, exposing the maximum of a device model range.
ICDs can be tailored to a project, exposing only the project related data.
Use case: A user needs to decide whether a given device is suitable for his application. Where can he check for an LN class, for mandatory and optional data provided in that device?
Today only the master-model ICD answers this need. A tool can help to read this file and to search for the data.
Proposal descriptions
ICD file is the key for the representation of the model implementation.
NSD is not the proper way for vendors to expose their implementation.
It is a tool issue to expose and user-friendly way of looking information inside ICD file.
UCA has a tool at http://www.ucaiug.org/org/TechnicalO/Testing/Shared%20Documents/Tools/Member_Free_Tools/SclViewer and http://www.ucaiug.org/org/TechnicalO/Testing/Shared%20Documents/Tools/Guest_Free_Tools/SclViewer
which can easily find proprietary LNs and DOs. It uses XSLT and a non-Chrome browser (such as FireFox).

2021-04-13: Clarify with Michael if the use case asks for the standard to specify such tool. A lot of work is being done in the standard regarding virtual IEDs, SCL comparison, and also OSMOSE project.
Far future: In the end, basic application profile could be the information to check if an IED complies with it.

2021-05-11: We would need ICT capabilities with the ICD in order to know what can and cannot be done. And if the device is completely flexible in data model, then it is not possible to use the ICD for the given purpose. So this issue applies to fixed data model (in the sense of logical node classes). We are looking for a tool that will need to use an ICD file and ICT capabilities to give user information and being able to check if it fits with the user specification.
It is a more sofisticated tool from ICT to check if the IED can commit with a given specification.
Possible flow:
1. The user should create the ISD
2. ICT should be able to check and confirm if it can fulfill the requirements
We should not mixed capabilities and requirements.
How do we know an IED has flexible data model? Today there is no information in the certificates giving this information.
We need to define different levels of flexibility:
- Rearrange structure of logical nodes
- Create new logical node instances
- Extending logical node classes.
- ...
We have an action to integrate as much as possible PICS and MICS in the service section of the IED.
Would it be possible to include also PIXIT?
There is more behind: ICD and also capabilitiesz, so it will be incomplete to use only the ICD file.

2021-06-16 (WG10 Plennary): Consider it par of 6-100, as it has introduced the concept of the ISD file. We need to look at that in this context. We need a longer discussion on that. We will keep it open.
Some feedback can be received from OSMOSE project.

- Assigned TF 61850-6-100 (Function modeling) added
User has to have proper tool to compare instances of specification and delivered e.g. LN.
Part 6 (Ed2.1) and 90-30 are delivering the resources for this process.
