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 meter readout Radio meter reading for operation in SRD bands.
Communication systems for meters and remote reading of meters. EN Part 3 of the standard addresses the dedicated application layer.
In this mode, the data collector may save power as the meter devices send a wake-up signal before sending their data. The most used modes today are the S, T, C and N modes, which are shown below. Visit our product page for more details. Part 3 of the standard addresses the dedicated application layer. Wireless Meter Bus has its origins within the Meter-Bus standards.
A variety of forms of modulation are used dependent upon the mode of operation. Send data a few times per day. 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.
Customers who bought this product also bought BS EN Stationary 137574- C2, Compact ENEN Dependent upon the application, one of ne number of communication modes can be selected. Section 4, EN addresses the wireless system. The different modes and functions are allocated different frequencies and also data rates that can be used. Similar to T1 but higher data-rate, 50 kbps.
This part of the standard addresses the Physical and Data Link Layers for wireless devices. Learn more about the cookies we use and how to change your settings. 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 een. Skip to toolbar About WordPress. Application layer, Datalink layer and Physical layer.
Communication modes There are different requirements for differing applications for WM Bus. Popups No Popups Loaded? Again, this is a bi-directional version of C1. Change text from Agreement option in Settings. 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. This is the Frequent T ransmit mode and metering devices periodically send data to collectors that are in range.
Find Rn Items This product falls into the following categories.
The relative simplicity of the stack makes it very energy and code efficient. 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. 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 website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. 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.
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.
This is a field bus standard aimed at applications for collecting meter data for gas, electricity, water, etc. Worldwide Standards We can source any standard from anywhere in the world. EN This part addresses relaying.
In this mode the data collector may request dedicated data from the metering devices. 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 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.
