4.2.6 Structure of load profile compilation
A status word is stored with each load profile record. Each bit in this status word contains information
about a certain error or event. Each time an event occurs that changes the status word, a new header
with the updated status word is generated and stored. The structure of header and the decoding of the
status word is explained below:
Example: Structure of the load profile header as an example load profile data set:
P.01(121015061841)(########)(5)(9)(C.1.9)()(C.5.1)()(C.5.3)()(0.9.17)()(0.9.18)()(1.29.0)(kWh)(2.29.
0)(kWh)(3.29.0)(kvarh)(4.29.0)(kvarh)
P.01
➔
OBIS-Code for load profile,
(121015061841)
➔
timestamp of load profile entry (format YYMMDDhhmmss)
(########)
➔
status word in hexadecimal coding (see below)
(5)
➔
recording interval in undisturbed case
(9)
➔
number of variables stored in the load profile
Then the OBIS codes of the stored values follow (possibly with their physical units) and finally carriage
return (0D) and line feed (0A).
The meaning of the bits of the status word is listed below.
If necessary, the status is composed by a plurality of individual bits, if multiple events are recorded.
This coding of the status word is also used in log (P.98) and is defined as follows:
