======  Engineer Standards ======
During our work on volkszaehler.org we got in contact with international standards. Here collected some resources which could be helpful when implementing protocols etc.

Most of the standards are maintained by one of the two smart metering commitees: **[[#DLMS UA]]** and **[[#OMS Group]]**

===== ANSI =====
  * [[http://tinyurl.com/3g7sr5x|ANSI C12.18]]: The optical port and PSEM standard for metering
  * ANSI C12.19: The data structure (tables) standard for metering
  * ANSI C12.21: The modem and PSEM standard for metering
  * ANSI C12.22: The network protocol standard for metering

===== OMS Group =====
**Open Metering System Group**

==== M-Bus (Meter-Bus) ====
Communication systems for meters and remote reading of meters

==== DIN EN 62056: Electricity metering - Data exchange for meter reading, tariff and load control ====
The series of DIN EN 62056 standards superseeds IEC 61107 and is used in Europe.

  * [[http://docs.volkszaehler.org/standards/din-en-62056-21.pdf|DIN EN 62056-21]]: Direct local data exchange (3d edition of IEC 61107) describes how to use COSEM over a local port (optical or current loop)

  * [[http://docs.volkszaehler.org/standards/din-en-62056-46.pdf|DIN EN 62056-46]]: Data link layer using HDLC protocol
  * [[http://docs.volkszaehler.org/standards/din-en-62056-47.pdf|DIN EN 62056-47]]: COSEM transport layers for IPv4 networks
  * [[http://docs.volkszaehler.org/standards/din-en-62056-53.pdf|DIN EN 62056-53]]: COSEM Application layer
  * [[http://docs.volkszaehler.org/standards/din-en-62056-61.pdf|DIN EN 62056-61]]: Object identification system (OBIS)
