This feature is only supported on firmware versions 2.01.000 or newer, and
requires a Compact Flash card to be installed.
The module supports the extended archive feature that allows you to configure
more archives than the regular 35 daily archives and 48 hourly archives. The
module supports the following number of extended archives:
Daily Archives Hourly Archives
Max Number of Archives 350 (version 2.04 and earlier)
1440 (version 2.05 and newer) 1260 (version 2.04 and earlier)

more information.
Note: The maximum number of extended archives is not dependent on the number of words per
archive. Extended archives are stored on a Compact Flash card which must be installed for
Extended Archive configuration to be effective.
Retrieving Extended Archives
The module implements an easy way to retrieve extended archives from the
Modbus database. To learn how to retrieve extended archives, click Archive
Config on the Meter Configuration dialog box, and then click Modbus Addresses.
For each archive file the module reserves a block of 50 Input registers to hold the
