Communication systems for and remote reading of meters - Part 2: Physical and link layer

EN 13757-2 Communication systems for and remote reading of meters - Part 2: Physical and link layer - This European Standard covers the physical and link layer parameters of baseband communication over twisted pair (M Bus) for meter communication systems. It is especially applicable to heat meters, heat cost allocators, water meters and gas meters. NOTE It is usable also for other meters (like electricity meters) and for sensors and actuators. For generic descriptions concerning communication systems for meters and remote reading of meters see EN 13757-1.
