6.11 Archives
6.11.1 Archive Overview
An archive is a set of data that records relevant process values that occurred
during a certain period of time (per meter channel). The archives are
automatically generated by the module and no further action is required. The
process values can include:

Net flow rate (average)
 Total accumulator
 Temperature (average)
 Alarms occurred during the period
The process values will depend on the meter type and product group as listed
later in this section.
Each archive contains two values that informs the period of time about that
archive:

opening timestamp = starting date and time for archive
 closing timestamp = ending date and time for archive
The example described in this chapter is of the default archive configuration as is
present for a newly allocated meter. Version 2.01 of the firmware and AFC
Manager allows the default configuration to be changed. Refer to Editing the
Archive Structure.
6.11.2 Archive Generation
The archives can be generated during one of the following situations:

Upon period end
 Upon event
 Upon processor command
