Recording data on networks M-Bus.

The device CPTM_Bus is a model that allows to read and record data from all instrumentation in M-Bus standard architecture, in a stand-alone mode trough Computherm's peripheral device or by any other system that supports this protocol. The M-Bus protocol is an open international standard that allows to exchange information from the slaves (gauges and counters M-Bus) to the master (network operator or CPTM-Bus). The management and the decoding of M.Bus protocol conforms to UNI EN 1434 regulations.

The device can be ordered in different versions: Master, Slave and Level converter:

MasterSlaveLevel converter
Master M-Bus Slave M-Bus Level Converter M-Bus

In the master and in the slave version there is a function to record the historical data from 250 instruments in a range of time programmable by hour or day. For example: a daily record of 250 instruments will go on 2 years.

The support with removable memory allows the configuration and the record of data. In case of failure the support can be installed in a new equipment, preserving the settings and the recorded data, assuring security and continuity of service. .

Moreover, an efficient system of differential unloading favors time and resources saving (specially by GSM).
