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 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
