DIN Standards Committee Heating and Ventilation Technology and their Safety
NA 041-03-66 AA
Communication systems for meters (Mirror committee CEN/TC 294)
The scope of the NA 041-03-66 AA „Communication systems for meters (Mirror committee CEN/TC 294)“ within the DIN Standards Committee Heating and Ventilation Technology and their Safety is the standardization of communications interfaces for metering and submetering systems for Water, Fuel Gases, Heat and similar energies and fluids where the protocols are applied to the meters, sensors and actuators and systems used to provide metering services.
Security features like Confidentiality, Authenticity and Integrity are provided at the application and lower layers.
Cooperation with CENELEC and ETSI, in relation to consistent protocol and use of spectrum, is an essential condition for achieving interoperability between entities in systems.
The NA 041-03-66 AA is the official German mirror committee of
- CEN/TC 294 "Communication systems for meters and remote reading of meters",
- CEN/TC 294/WG 2 "Application layer for communication systems for and remote reading of all meters within the scope",
- CEN/TC 294/WG 4 "Data exchange for meters on bus-systems and interface" and CEN/TC 294/WG 5 "Radio meter data exchange",
- CEN/TC 294/WG 6 „Data exchange for meters on wireless mesh networking systems“ and
- CEN/TC 294/WG 7 „Adaptation layer“.
As mirror committee the NA 041-03-66 AA is also responsible for the nomination of German Delegates and German experts for CEN/TC 294, CEN/TC 294/WG 2, CEN/TC 294/WG 4, CEN/TC 294/WG 5, CEN/TC 294/WG 6 and CEN/TC 294/WG 7.
