1777   Issue with ValKind for FC EX and some other FCs

Created: 03 Jun 2021

Status: Discussion (red)

Part: Part 6 (2019; Edition 2.1)


Page: 124


Paragraph: Table 46


According to table 46, the only ValKind that applies to DAs with FC EX is Conf and it only applies to data attribute dataNs.

This would mean, that an attribute dataNs can not be visible online from the IED. However, having visibility online of attributes declaring namespaces may be useful for clients.

Further, it is unclear what applies to data attributes ldNs and lnNs - those definitely shall be visible online as some of the compatibility rules introduced with Ed 2.1 may require the client to understand what namespace an IED is using. But according to the text before table 46, valKind shall be ignored for all cases not specified in table 46 but it is not clear what it then means.

Further, table 46 specifies how operational process values are handled. But what belongs to that? Only ST and MX? Or as well SR, BL and OR?

Finally, the engineering process stage mentioned in this table are as well unclear. E.g. What is IED engineering and what is IED configuration?


Consider to improve table 46; e.g.

- Add all DAs with EX to RO
- Mention FC SR, BL, OR and SV
- In the column about engineering process, refer to definitions either from within part 6, e.g. as documented in Fig 1 - 4; improve those figures if needed or from part 4.
