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.

See our application note AN for further details. EN Part 3 of the standard addresses the dedicated application layer. Again, this is a bi-directional version of C1. The Wireless M-Bus standard was first published in and has since been improved based on feedback from several thousands of field installations in very harsh environments — after all, many water and gas meters are located below ground level, in remote basements, sheds, or culverts.
Part 1 of the standard defines the data exchange, detailing the 17357-4 communication between meters and a central data collector.
Radiocrafts Wireless M-Bus modules support the commonly used dialects and modes as described above, operating as complete modems, both on the device and collector side.
Search all products by. This is a S tationary mode and within this, metering devices send their data several times a day. Click to learn more. The relative simplicity of the stack makes it very energy and code efficient. The EN protocol stack itself has three different layers: Dialects have been developed, or are being developed, to meet various regional requirements.

Wireless M-Bus was originally defined for Smart Metering i.

It includes a variety of proposals for relaying data frames as a means of overcoming issues related to range between the meter and the data collection points.
ENEN Wireless Meter Bus has its origins within the Meter-Bus standards. In this mode the data collector may request dedicated data from a metering device.
Popups No Popups Loaded? A total of three different data rates are specified along with one way or two way communication. EN This part of the Meter Bus standard addresses the physical and link layers for the physical data transmission using wired connections.
Wireless meter readout Radio meter reading for operation in SRD bands. Radiocrafts also has Wireless M-Bus modules with integrated sensor interfaces to further speed sensor integration and lower the costs for the customer. Also defined in the EN standard are the R, Q, P and F modes, but they are rarely or never used, so they are not within the scope of this summary. Take the smart route to manage medical device compliance.
Customers who bought this product also bought BS EN Meter Bus Standard EN Parts Standard Specification Details EN Part 1 of the standard defines the data exchange, detailing the basic communication between meters and a central data collector. If you are designing an industrial WSN that will not communicate with devices from other suppliers, then you can view the dialects as best practices that can be used or not used as you decide.
The Wireless M-Bus standard application layer provides for sending any sensor data, not just metering data, from the device to the collector using the descriptor DIF and VIF and the actual data in encrypted format. Wireless M-Bus Technology Overview. We will notify you as soon as we answer your question! EN This part addresses relaying. The most used modes today are the S, T, C and N modes, which are shown below.
It describes the standard application protocol used to enable a multivendor capability, thereby enabling devices from several different vendors to operate in a single system.
This part of the Meter Bus standard addresses the physical and link layers for the physical data transmission using wired connections. This particular form of mode is useful for walk-by or drive-by data collection C2 Bidirectional Again, this is a bi-directional version of C1. The Wireless Meter Bus or Wireless M-Bus is aimed at remote reading of gas or electricity meters as well as any other types of meters that may need to be read remotely.
