Wireless M-Bus Products

Wireless M-Bus is a very robust and power efficient protocol that was developed as a standardized solution for wireless meter reading (EN 13757). Key considerations were always low power for battery operations and a high level of security to meet the requirement in the meter-market. This makes the wMBUS an ideal solution for the metering application but also any Industrial application that needs a secure, robust and low power wireless connection. The use of an RF module ensures standard compliance, and the flexibility to choose between different modes and frequency bands. An RF module from Radiocrafts is always compatible with the latest additions of the standard as we take actively part in the standardization work in both CEN and OMS.

RC11XX-MBUS3 Family

RC11 series is a cost effective sub-GHz platform that supports 433/865/868/915 MHz modules. MBUS-3 is designed for battery operated devices, where the slave is always initiating the communication, and the master must then transmit (if need) within a short time window (2-3 ms in the T mode). After one such “ping-pong” sequence, the slave will have a pause (enter sleep mode) for 2-5 seconds, before it again do a new transmission allowing the master to do another transmission

RC17XXXX-MBUS4 Family

An upgraded version of RC11 series, which includes extra feature of the Ultra Narrowband radio for the best noise resilience. High Power for the extended range is available for this family. The MBUS4 supports the mode N (169 MHz) variant of the Wireless M-Bus standard as specified in the preliminary EN 13757-4 (2013). The MBUS4 functionality is similar to the MBUS3 functionality, with the addition of the Master supporting 256 meters (Slaves) internally and > 1000 Slaves registered externally (in the host).

RC1XXX-MPC Family

The stand-alone Wireless M-Bus module with Pulse counter, Tamper and Install inputs. The module communicates with the Radiocrafts MBUS3/MBUS4 modules and automatically at configurable intervals. The module is normally in sleep mode with ultra-low power consumption. A pulse-output from any meter (like gas-, water-, heat- or electricity meter) is connected to the pulse input pin on the module. At a configurable interval, the module wakes up and makes an RF transmission of the accumulated value.

Product Details

The Wireless M-Bus RF Transceiver Modules are compact surface-mounted high performance modules with embedded Wireless M-Bus protocol. The RC11xx series cover 868 MHz, as well as variants at 433, 865, 869, and 815/923 MHz. The RC17xx series cover 169 MHz. The (MBUS3, MBUS4) module can be configured to operate as Slave (in the meter), Master (in the concentrator), or as Repeater (single hop).

The modules (MBUS3, MBUS4) have an easy to use UART interface for serial communication and configuration and a one-pin antenna connection. When used with quarter-wave antennas a line-of-sight range of over 800 meters can be achieved at 868 MHz, and several km at 169 MHz. Ultra-low power mode extends battery lifetime.

The MPC1 (M-Bus Pulse Counter) variant contains an autonomous application for pulse counting, alarm supervision and transmission scheduling. It also supports over-the-air configuration and installation.

Configuring a Wireless M-BUS Network

A Wireless M-Bus network is very easy to configure, if configuration is needed at all. In the simplest case, the Meters are one-way transmitters, and the Concentrator or Reader is the receiver. The receiver can in principle receive data from any meter sending a valid Wireless M-Bus message. Or the receiver can register the unique addresses of each meter and filter the data based on this. Data encryption will of course ensure data privacy and integrity, preventing data to be understood or manipulated even if the message can be received by any radio.
Each meter (or radio module connected to the meter) has a unique 8 byte ID or address. The address consists of a Manufacturer ID, a serial number, the device type (e.g. water meter) and the version of the meter (product revision). In this way each manufacturer can ensure that every meter deployed in the field has unique addresses.

The Wireless M-Bus protocol was invented and developed for battery operated meters. Hence it is optimized for very low power consumption, even for two way communication. The method to achieve this is that the meter provides a short reception window after the message transmission. The concentrator should in this case make a transmission to the meter within this short time window. Any command to a meter, must therefore be prepared and sent exactly when the meters own receiver is turned on. Radiocrafts has patented solutions for how this is handled autonomously by a compact radio module in the concentrator. Because the communication is encrypted, messages must be decrypted and encrypted as part of the time critical communication sequence. This is solved by an intelligent and configurable message generator and mailbox system within the radio module.
Wireless M-Bus also allows for Repeaters. The MBUS3 implementation contains single-hop repeater functionality. When the module is configured as a Repeater, it will receive data from any meter, and re-transmit the message after a few seconds (random delay to avoid collisions). The repeated message is marked with a flag, so that it will not be repeated a second time, avoiding endless repetition loops in the network.
The MBUS modules from Radiocrafts are easily configured using the MBUS-DEMO tool. This PC tool also includes a packet sniffer and packet generator simplifying laboratory tests. All configurations and data communication are done over a UART interface.

Using the Radiocrafts Wireless M-Bus module makes it very easy to generate a valid M-Bus packet. When the module has been configured for the desired mode (T, S, C etc) and device type (e.g. as Slave for use in a meter), simply send the application layer data string preceded by a length byte. The module will then add the rest of the protocol used in the radio transmission, and even do the data encryption if desired.

wireless m-bus

What is Wireless M-Bus?

Wireless M-Bus is the only European standard (norm) for wireless meter reading (EN 13757). The standard was originally developed for communication with battery operated gas, water and heat meters, operating at 868 MHz with a focus on low power consumption and low implementation cost. The standard has later been updated and expanded to include narrowband radio, security (encryption and authentication), and repeater networks. It supports all types of utility meters as well as environmental sensors. Wireless M-Bus is the basis for OMS (Open Metering System) and other national companion standards (France, Italy, Netherlands) for meter reading.
