11.4 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 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 package, 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, in paragraph
Info codes). The daily and monthly loggers show all info codes, which have been active since the latest
logging.
