Wireless M-Bus 3 Key points

Only European Norm for wireless metering Field proven in millions of meters ed by all major metering companies in Europe

© Radiocrafts AS

Wireless M-Bus Basics  Slaves reporting to Master (concentrator)  Slave receives acknowledge with minimum time response

Message decryption and acknowledge within 2-3 ms

Meter wakes up and transmits reading (gas: each 30 min)

Ack can contain ’shut valve’ command

Water: TX each 4 hours (with random time-spread)

Background  Standardization work -> Cenelec, TC 294  EN 13757 standard “Comm. Syst. for remote reading of meters”

 EN13757-4:2005: Wireless Meter Readout  -3 M-Bus application layer  -1 DLMS application layer

 The Netherlands: NTA8130 as of Feb 2006 (last revision of Jan 2009)  : OMS specification released September 2009  TC 294 again active (re-launched July 2009)

EN13757-4:2005  “Stationary Mode” S  Unidirectional, S1, or bi-directional, S2  32.768 kb/s, 868.3 MHz

 “Frequent transmit mode” T  Unidirectional, T1, or bi-directional, T2  100kb/s, 868.95 MHz

 “Frequent receive mode” R  10 channels, 4.8 kb/s

NTA 8130 (DSMR)  Netherlands Technical Agreement 8130  Dutch Smart Meter Requirements  P2 interface  Max 4 metering instruments and/or grid company equipments in each metering system  Defines T1 / T2 and AES128

OMS  Open Metering System specification  Assured co-existence with NTA 8130 / DSMR  Unified approach for the different media (electricity, gas, heat and water) as well as actuators and displays  Interoperation  Optimized for battery lifetime of > 14 years  Installation ed

OMS cont.  MUC (Multi Utility Controller): Intelligent concentrator between AMM and the devices  Either S or T mode and AES 128 encryption MUC <-> meters  OMS is being reviewed by CEN as European new work item proposal TC294
