4. GENERAL INFORMATION ON THE SYSTEM
4.1.1 Overview of the system
GE552Y051 is a consumption monitorin and meterin system based on a standard wired M-Bus
communication protocol (EN13757-2 [Physical Layer], EN13757-3 [Application Layer]). All the meters that
use this communication protocol can be connected and will be mana ed by the system with all the
functions it features.
Figure 2 - System architecture
GE552Y051 can mana e up to a maximum of 250 wired meters. GE552Y051 has an inte rated
communication port that supports up to 20 M-Bus meters. It is possible to extend the number of wired
connected meters (up to 250) throu h the use of level converter (reference code in GIACOMINI catalo :
GE552Y050) with inte rated repeater functionality (see Fi .2 ). A sin le level converter is able to mana e up
to a maximum of 60 M-Bus nodes. If in the system there were more than 20 M-Bus nodes to mana e with
the same GE552Y051 one or more level converter in repeater mode can be used.
4.1.2 M-Bus system
M-Bus (Meter-Bus) is a European standard (EN 13757-2 [phisical and link layer], EN 13757-3 [application
layer]) for remote readin of water, heat, as or electricity meters. M-Bus is also usable for other types of
consumption meters. The M-Bus interface is desi ned to communicate on two wires, for which ensures
enormous convenience.
The M-Bus protocol has been developed to have available a system for remote readin and mana ement of
meters networks of utilities , for example to measure the consumption of as or water in the house. This
bus meets the special requirements of systems remotely and/or battery powered, includin meters usually
prepared from utilities at consumers.
The advanta es of the M-Bus system are
•Hi h level of data transmission security
•Low wirin costs
•Lon distances without requirin repeaters
•Lar e number of central units
•Detection of both battery-powered and mains-powered devices
•Automatic device reco nition

9
•Vast array of systems and components available
•Different types of bus topolo y: linear, star, and tree
Figure 3 - Bus topologies
4.1.3 Addressing
The M-Bus protocol provides two types of addressin modes to detect and communicate with the devices
connected to the bus
•Primary addressing: up to 250 primary addresses can be allocated within an M-bus system
(hexadecimal format). The primary address is normally allocated while settin up the units.
•Secondary address: the secondary address consists of 8 bytes and allows the allocation of any
number between 00000000 and 99999999. By default, the secondary address of the devices is the
same as the manufacturer serial number. Readin s by secondary address while scannin the bus
allow the acquisition of the meters that support the “Wildcard” lo ic, the same that enables the
selection of a roup of devices based on the section of their serial number.
