Description

IEC 62361-102 Recommendation R8:

The SCL method of modelling equipment that is not connected is inconsistent with CIM
models. The CIM allows Equipment and their Terminals to be defined regardless of whether
they are connected or not. Allowing unconnected terminals to be indicated by possible (but
not guaranteed) removal of a terminal element does not facilitate automatic mapping.

In IEC 61850-6 Table 6 Attributes of the Terminal element, change the description ConnectivityNode.
Current text: “If the Equipment shall not be connected, then the whole Terminal element shall
be removed.”
Proposed text: “If the Equipment shall not be connected, then the whole Terminal element
shall be preserved. The Terminal attribute connectivityNode may be the name of a normal
ConnectivtyRule or it may have the special value ‘None’”.
