RTAP Historical Archiver

The Historical Archiver converts RTAP historian tables into CSV (Comma Separated) files with the following format:

        YYYY-MM-DD_<hist>.csv

where:

• YYYY = year (eg. 1994)
• MM = month (eg. 07)
• DD = day of month (eg. 01)
• <hist> = historian table's alias with spaces converted to '_'

The data is saved as follows to the file:

"<time>",item 1,item 1 quality,item 2,item 2 quality,...
"<time>",item 1,item 1 quality,item 2,item 2 quality,...

where:

• <time> = time of sample
• item 1 = value of item one
• item 1 quality = quality of item 1
• <time> = time of sample
• item 2 = value of item two
• item 2 quality = quality of item 2

The number of items is dependant upon how many items have been configured for the history table.

These archived historical files can then be viewed through the RTAP trending sub-system using an rtsh script.
