Table 4.5: Status word bit coding
The header is followed by sets of nine (for standard version) measuring values until the next event
generates a new header.
In the standard version the following values are recorded in the load profile:
• C.1.9 Consumption Point ID (according to EN 50463-1:2017), a max. 32 ASCII characters
comprehensive text string
• C.5.1 Status of this load profile entry ("Quality flag" according to EN 50463-3),
three bytes in the following code:
