Issue

Figure 49 currently duplicates Figure 48.

Proposal

The current Figure 49 shall be replaced with a new figure illustrating the content described in Section 4.3.3.8.

Discussion Created Status
Thank you for identifying the figure to be presented as Figure 49.
The attached figure requires minor editorial corrections. Please refer to the following suggestions:

The data object (DO) “ReqDifW” in OperationalFunctionLN3 and OperationalFunctionLN4 should be replaced with “ReqW”, as IEC 61850-7-420 does not define ReqDifW as a data object.
The DO “GnSpt1” in DWGC4 and DWGC5 should be replaced with “WSpt”.
DPMC4 contains two instances of “WSpt2”. The WSpt2 shown on the left side of DPMC4 should likely be ReqW1 or ReqTotW.
The DO “WSpt1” in DEResourceLN4 should be replaced with “WSpt”, as this data object is not defined as a multiple instance.
DEResourceLN5 should be positioned on the lower right-hand side of the figure. 		08 Feb 26 Triage
