Wireless M-Bus or Wireless Meter-Bus is the European standard (EN ) that specifies the communication between utility meters and data loggers. The Wireless M Bus specification EN defines six different . Mode N: preamble length is configurable (value required by EN is 2 bytes). This document (EN ) has been prepared by Technical Committee CEN/TC “Communication systems for meters”, the secretariat of which is.

Radiocrafts has developed a document that serves as a simple way of designing and setting up the network, without having a deep understanding of all the features and option that comes with the standard. Optimized for battery operation and stationary operation. The most used modes today are the S, T, C and N modes, 1357-4 are shown below.
Wireless Meter Bus, WM-Bus Technology
Wireless M-Bus RF layer The physical layer for the Wireless Meter Bus needs to be relatively straightforward to enable the system to operate reliably and over long periods of time. This part of the Meter Bus standard addresses the physical and link layers for the physical data transmission using wired connections.
S2 Bidirectional This is essentially a bidirectional version of the S1 mode. In this mode the data collector may request dedicated data from a metering device. This is a field bus standard aimed at applications for collecting meter data for gas, electricity, water, etc. Ne M-Bus is designed to be a robust, power efficient, long range wireless communication solution that operates in the license-free ISM bands.
Wireless M-Bus Technology Overview – Radiocrafts
Communication systems for meters and remote reading of meters. Similar to T1 but higher data-rate, 50 kbps.
Supplier Directory For everything from distribution to test equipment, components and more, our directory covers it. Dependent upon the application, one of a number of communication modes can be selected.
See our application note AN for further details. EN Part 3 of the standard addresses the dedicated application layer. Change text from Agreement option in Settings. EN This part addresses relaying. The EN protocol stack itself has three different layers: The different modes and functions are allocated different frequencies and also data rates that can be used.
In this mode the data collector may request dedicated data from the metering devices. This is the Frequent T ransmit mode and metering devices periodically send data to collectors that are in range. EN has six parts, including EN which includes the Wireless M-Bus specifications for radio-based communications between utility meters and concentrators or smart meter gateways:.
