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 reg

The info codes and info code hour counters are brought together in one register for presentation in
loggers, the Wireless M
-Bus information packet 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 packet 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.

Info codes
The first 4 bits for info codes represent DRY, REVERSE, LEAK and BURST as shown below. The info code is
active when the bit value is 1.
In the Wireless M
-
Bus packet, in the info logger and in read
-
outs of the current info register via the optical
eye, the current status of the info codes is shown (also see different update of DRY, paragraph 8.7.4). The
daily and monthly loggers show all info codes which have been active since the latest logging.
