EN 13757-4 PDF

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.

A variety of forms of modulation are used dependent upon the mode of operation. Wireless M-Bus is designed to be a robust, power efficient, long range wireless communication solution that operates in eh license-free ISM bands.

Wireless Meter Bus, WM-Bus Technology

This particular form of mode is useful for walk-by or drive-by data collection. This is Wireless M-Bus Wireless M-Bus is designed to be a robust, power efficient, long range wireless communication solution that operates in the license-free ISM bands.

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.

Communication modes There are different requirements for differing applications for WM Bus. 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. Customers who bought this product also bought BS EN The faster, easier way to work with standards. Communication systems for meters and remote reading of meters.

Wireless M-Bus Technology Overview – Radiocrafts

EN This part addresses relaying. EN Section 4, EN addresses the wireless system.

Wireless Meter Bus has its origins within the Meter-Bus standards. Dependent upon the application, one of a number of communication modes can be selected. Note that also non complex set-up will take benefit of the build in robustness, power efficiency and security in the protocol. 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.

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. 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. The most used modes today are the S, T, C and N modes, which are shown below. It also describes the protocol used for the transmission of data.

EN Part 3 of the standard addresses the dedicated application layer. The Wireless M-Bus has several options that may be chosen for the radio parameters. This part of the Meter Bus standard addresses the physical and link layers for the physical data transmission using wired connections. Again, this is a bi-directional version of C1. Radiocrafts also has Wireless M-Bus modules with integrated sensor interfaces to further speed sensor integration and lower the costs for the customer.

Dialects have been developed, or are being developed, to meet various regional requirements.

Wireless M-Bus Technology Overview

EN This part of the Meter Bus standard addresses the physical and link layers for the physical data transmission using wired connections. It is similar to the ‘T’ mode but allows for the transmission of more data within a given energy budget and the same duty cycle.
