Detailed Description

Day start values.

This structure combines mainly meter reading values for import and export work (cf. makros Wimp, Wexp, PL1 etc.) to be put in / got from a binary daily retain file.

Attention: Variables of this type dayStrtVal_t are kept in shared memory by several programs. Changing order or size for sake of one program almost certainly will spoil the others.

Field Documentation

stmpSDay

uint32_t stmpSDay

Absolute time stamp for the day's start values.

This stamp marks the import and export work values of a successful meters reading very early in the current day. If a early day reading was neither taken nor read from retained values the application would put the first successful reading after program start here.

0 marks no values taken so far.

meterValDay

float meterValDay[2][2]

Start day meter values.

This array contains for every meter the import and export work as quadReg_t.f[0] and [1] respectively taken at dayStrtVal_t.stmpSDay.

valQual

uint8_t valQual

Quality of the values.

0: invalid
1: taken any time of day at program start
2: taken at predefined (fixed) time at change of day

Note: Even when having high quality values (for consecutive days), consider days may have 23 or 25 h in zone time, also.
