Introduction to M-BUS

M-BUS (Meter-Bus) is a communication protocol used for remote reading of gas, water, heating, and any other type of consumption meter. M-BUS enables interoperability between different building systems and devices in building automation and control applications. Developed by Dr. Horst Ziegler of the University of Paderborn in cooperation with Texas Instruments, M-BUS is made for communication on two wires, making it a cost effective option. It is a European standard (EN 13757-2 physical and link layer, EN 13757-3 application layer).

Our Commitment to M-BUS

The FieldServer protocol gateway configured as an M-BUS master device has the ability to change each slave to a desired standard M-BUS baud rate automatically. It can also power the M-BUS network internally and thus save expenses and wiring of a level converter. The FieldServer can also manipulate and relocate data for greater efficiency and performance.

M-BUS Interoperability

M-BUS devices often need to be connected to other networks. For example, in a building, it might be necessary to integrate the data produced by an M-BUS-speaking gas meter to a BACnet/IP or LonWorks or KNX based Building Automation System (BAS). M-BUS devices in the field may also need to present their information to a cloud service that speaks XML.

The FieldServer protocol gateways and converters can connect M-BUS devices to various management systems or device networks based on other protocols. Integrators and installers use our gateways for their flexibility, reliability, and ease-of-use, while OEMs often incorporate the FieldServer protocol gateway technology into their devices in lieu of doing their own protocol development.

Products

The FieldServer protocol gateways and converters can connect M-BUS devices to various management systems or device networks based on other protocols. The products are configured with the appropriate M-BUS hardware and driver along with the other required protocol drivers. Buyers usually order one of the hardware platforms below, select M-BUS as one of the drivers, and specify the other drivers they want loaded on it.

M-BUS Converters and Gateways for Integrators

Integrators value the flexibility and ease-of-use offered by the FieldServer protocol gateways because it allows them to complete their integration projects quickly and with low risk. The following products are available to integrators:

M-BUS Converters and Gateways for OEMs

OEMs embed the FieldServer protocol gateways with their products as it enables them to present their native M-BUS device as a multi-protocol device (without increasing R&D costs) that can work in networks that use other control networking standards.

Protocol Drivers

M-BUS protocol converters and gateways are ordered with the following protocol driver:

The gateway is also ordered with one or more of the following protocols depending on what type of device or network is being translated to and from M-BUS:
