8.4. Logger
The logger utilizes circular buffer in FLASH memory. When it is full, the new data overwrites the oldest
one. In this manner FLASH memory stores full log all the time. There isn’t a command to clear the log.
A copy of the full log is always available for download.
The number of records depends on how long descriptions and what kind of characters are used. In
the worst case (15 bytes description with characters from the highest part of UTF-8) a number of
records are about 52000. This number is enough for 36 days with records on every 1 minute.
The new data can be periodically uploaded as a file to a dedicated HTTP server in time intervals
– 1,
2, 3, 4, 6, 8, 12 and 24 hours. The data is sent in CSV format. A semicolon is used as a delimiter.
The first row of the log file is always header. All rows, including the header, start with record ID and
time stamp.
The structure of one row (record) of the log is as follows:
ID Time Type of record Inputs value Relays
Alarm
conditions
ID 32-bit unique number for every row (record).
Time time stamp of record, in format yyyy.mm.dd, hh:mm:ss.
Type of record following types of records are available:
"Time"
for periodical record;
"Event" for record initiated by alarm condition;
"Type" for header record;
"Start" after power-up condition;
"Restart" after reset condition;
"Power Down" after power-down condition;
"Bad" for a problematic record.
Inputs value in orders – sensors, analog inputs and digital inputs.
Relays relays conditions.
Alarm conditions show condition for every input, “1” means an active alarm.
