Category: Issue may impact interoperability of implementations of Edition 2
Issue: The definitions of valKind in Table 46 have in a couple of places indications like "IED template, after IED engineering". In the sentence following table 49, it is stated that "This allows, for example, the definition of IED capabilities..."
However, if we take the specification for RO with FCs CF, DC and settings, it is stated that:
- this applies to the IED template OR after IED configuration
- that it is a read only value at the IED that can only be set at configuration time
so what exactly does this mean? Is it allowed for a system configuration tool to set that value? If yes - how can an IED then indicate that the value is FIX? If no - how can a system configuration tool set a value but still indicate that the value shall be read only later? Obviously, as stated in chapter 5.4, a system configurator is allowed to set configuration and parameter values.
Of course, the ICD file could declare such an attribute as "Conf" but this would be a bad solution, because then it is as well not visible in the data model.
It looks like we are missing here some granularity?
Proposal: we should add something like a further option "FIX" or maybe "fix-conf" and "fix-RO" if we still want to support the non-visibility of configuration attributes (what I anyway would discourage).
