M-Bus (Meter-Bus) is a European standard (EN 13757-2 physical and link layer, EN 13757-3 application layer) for the remote reading of gas or electricity meters.

M-Bus is also usable for other types of consumption meters. The M-Bus driver is compatible with all devices that support the M-Bus protocol.

To use this driver, or to evaluate it, you need to download the last release of eWon Drivers eXtender from the Download section.

With eWon Drivers eXtender you can retrieve, from one or more M-Bus devices, the available data.
