Data Archiving

Hourly for 2 days for each meter run (48 records per channel)

Daily for 35 days
Note: The number of archives depends on the archive size you have configured. The default
values for a 30 word archive are 48 hourly archives and 35 daily archives.

Extended Archive feature supports up to 1440 daily archives and 1440 hourly
archives stored on Compact Flash

Each record consists of nearly 20 process and other variables. All archived
data is available in the onboard Modbus memory map.

User may configure when archives are generated

User may configure archive content (from pre-defined list)

Archives can be exported to an Excel spreadsheet or printed to a local
printer.
