M-Bus Specification Notes

Wired M-Bus specification summary.

The public M-Bus documentation is organized into introduction, serial bus basics, M-Bus overview, physical layer, data link layer, application layer, network layer and appendix. This page is a short signpost, not a copied manual.

Important disclaimer

The public documentation itself notes that it reflects late-1990s M-Bus specification material and is for information only; current product design should refer to the official current specification.
