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.

Wireless M-Bus was originally defined for Smart Metering i. Using Wirelss M-Bus for your network can be a simple task, or a complex mission, depending on what features you intend to use.

Note that also non complex set-up will take benefit of the build in robustness, power efficiency and security in the protocol. Radiocrafts has developed a document that serves as a simple way of designing and setting up the network, without 137757-4 a deep understanding of all the features and option that comes with the standard.

Wireless M-Bus is e to be a robust, power efficient, long range wireless communication solution that operates in the license-free ISM bands. 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 dialects see below and modes used in automatic meter reading AMR applications are set by the utility company and driven by their requirements. For industrial WSN applications that are proprietary in nature, the dialect and mode can be chosen based on achieving optimum performance, while leveraging the built-in effectiveness, robustness, and security of the Wireless M-Bus standard.

Radiocrafts can provide recommendations on what to choose based on the desired performance.

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. See our application note AN for further details. 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:.

EN is a very flexible and open specification, where some parts are not described in detail or left for future implementation.

The full, current EN standards are available on-line from http: 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. Eb also has Wireless M-Bus modules with integrated sensor interfaces to further speed sensor integration and lower the costs for the customer. Visit our product page for more details.

The most used modes today are the S, T, C and N modes, which are shown below. 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 133757-4. Optimized for battery operation and stationary operation.

Similar to T1 but higher data-rate, 50 kbps. Stationary operation C2, Compact The EN protocol stack itself has three different layers: Application layer, Datalink layer and Physical layer. The relative simplicity of the stack makes it very energy and code efficient. Dialects have been developed, or are being developed, to meet various regional requirements.

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.
