An existing log will always be deleted when configuration is changed.
Modules 60-65 (without logging) can be re-configured to 40-42 (with logging)
17.6 Hour counter
Each info code, DRY, REVERSE, LEAK and BURST, has a corresponding hour counter. The hour counters are
incremented by one every hour, counted on the meter's clock, the corresponding info code is active.
Counting starts immediately the first time the info code is active within the hour in question. Even though the
info code occurs more than once within an hour, the counter is only incremented once. If the info code remains
active for several hours, the counter is incremented by one for each hour. The increment is independent of how
small a part of the hour the info code is active.
Please note: The info code ‘DRY’ is set in two steps, the increment of the hour counter follows the second step.
See paragraph ‘ Info register ’
The hour counters cannot be accessed directly but are represented in the info register in coarse resolution. See
paragraph
‘ Info register ’
No hours are counted as long as the meter is in transport mode.
17.7 Info register
Every time the information code changes, date and info code are logged. Thus, it is possible to data read the
latest 50 changes of the information code as well as the date the change was made. Reading is only possible via
the optical eye. The table below represents an overview of the register.

The info codes and info code hour counters are set together in one register for presentation in loggers, the
Wireless M-Bus information package and read-outs via the optical eye. The information has been compacted in
order to reduce the quantity of data in the Wireless M-Bus package and partly also in the loggers.
The register size is 2 bytes, apportioned with 4 bits for info codes and 12 bits for the info code hour counters. The
distribution is shown below
– the numbering shows the bit position.
