WG10 Proposal:

Closed because solved with 7-1 (part ExtRef), part 6 ED 2.1 annex H and by issue#5 ENTSO-E (generic interface LN).

To discuss in WG10:
Short Proposal:

Ed 2 partly solves this issue. The guideline should describe the prefered way.

Description

Common vendor practice is to have generic interfacing logical nodes for outputs and inputs. This destroys the semantic meaning of signals. Likewise the use of inputs to generic LN (e.g. LDO) rather than the LN actually using the input makes documentation of information flow from SCL difficult. In order for the information flow to be recreated from SCL (without referring to propriety configuration information in vendor tools) it is required that Ed2 srcLN attributes are used in Input/ExtRef elements and that relevant placement of Inputs is enforced (according to part 6ยง9.3.13). We see this as an issue for both profiling and description in guidelines within the standard. Guideline for using SCL as documentation is specifically needed.
