The following rules applies for the fileformat SVEF/24:
•Every file can contain one or several value-series.
•The values must be in timeorder for every 24 hour serie. However, the series does not need to be in timeorder between themselves.
•Every day must have 24 hours in the file.
•The unit is always MWh.
•One line in the file contains one hour value.
•Empty lines may occur.
•A line is a commentary line if it starts with // and is treated by the system as if it was an empty line.
•The first line of the file must have the following
text.
SVEF/24:1/<timedate>
Where <timedate> is the date when
the data was created, sampled or written to the file,. The date is needed
because if the file is transferred using for example FTP, two files containing
data on the same measurand, and date, (original values followed by updated
values) might not come in correct order and thus resulting in incorrect
information. The syntax of <timedate>
is:
YYYY-MM-DD

(00-23)
MI the minute with 2 digits
(00-59)
SS the second with 2 digits (00-59)
Every value-line should have the following format:
<measurand> <tab> <timedate> <tab> <status> <tab> <value>
<measurand> the name of the measurand
<timedate>
syntax: YYYY-MM-DD
