  1. Open wireless standardsWireless M-Bus, KNX RF, ZigBee, 6LoWPAN Hallvard Moholdt, Technical Solutions Manager Ørjan Nottveit, Product Line Manager www.radiocrafts.com

  2. Agenda • AMI overview • Wireless M-Bus • NTA8130 • OMS • KNX RF • ZigBee • Total cost of ownership (TCO) • Q&A

  3. AMI WAN NAN HAN/LAN

  4. HAN/LAN Gateway

  5. Why open standards • Open standards enable interoperability • Open standards give multi-vendor ecosystem and hence lower cost • What are open standards • EN/IEC/ISO • IETF • Industry standard

  6. Wireless M-Bus

  7. figawa,

  8. Wireless M-Bus 3 Key points • Only European Norm for wireless metering • Field proven in millions of meters • Supported by all major metering companies in Europe

  9. Wireless M-Bus Basics • Slaves reporting to Master (concentrator) • Slave receives acknowledge with minimum time response Message decryptionand acknowledge within2-3 ms ((())) ((())) ((())) Meter wakes up and transmits reading(gas: each 30 min) ((())) ((())) Water: TX each 4 hours (with randomtime-spread) Ack can contain ’shut valve’ command ((()))

  10. 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) • Germany: OMS specification released September 2009 • TC 294 again active (re-launched July 2009)

  11. 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

  12. 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

  13. 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 asactuators and displays • Interoperation • Optimized for battery lifetime of > 14 years • Installation supported

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

  15. System topology

  16. RC1180-MBUS module • Embedded protocol • supporting EN 13757-4:2005 mode S, T and R2 • AES 128 HW co-prosessor • 12.7 x 25.4 x 3.3 mm • compact module for SMD mounting • No configuration required • 4 pins + gnd connection • 2.0 – 3.6 V supply voltage • ultra low power modes

  17. RC1180-MBUS module • 2 channels in mode S and T • 868.3 and 868.95 MHz • 10 channels in mode R2 • 868.03 + n x 0.06 MHz • CE marked • Conforms with EU R&TTE directive • EN 300 220, EN 301 489, EN 60950 • Designed for EX compliance • High temperatures

  18. Feature sets standard

  19. High-end performance • Output power typical 10 dBm • Excellent receiver sensitivity • Typical -102 dBm at 32.768 kbps • Excellent blocking • >-45 dBm at 2 MHz offset • Two way communication simplifies installation compared to only one-way • 8-900m range / quarterwave antenna

  20. UART : Data in – RF out

  21. Micro- controller Wireless M-Bus communication modem EN 13757-3 EN 13757-4 Customer Application UART GPRS modem UART Ethernet gateway UART

  22. M-Bus application module • Tailoring to different end users requirements Pulse input Innstallation button input Status LED output UART for reading meter info

  23. MUC platforms: RC1180-MBUS+ GPRS/GSM / Ethernet RC1180-MBUS
