DLMS: Smart Meter Protocol Stack

Device Language Message Specification (DLMS) 
(originally Distribution Line Message Specification)
IEC 62056

Through a partnership with Kalki Communication, Microchip is now able to provide a Device Language Message Specification (DLMS) protocol stack optimised for its 16bit PIC microcontrollers. The company claims that the DLMS protocol has become the worldwide standard of choice among smart meter designers for interoperability.
The acceptance of DLMS is said to cover most energy types (electricity, gas, heat and water), multiple applications (residential, transmission and distribution), and numerous communication media (RS232, RS485, PSTN, GSM, GPRS, IPv4, PPP and PLC); as well as secure data access, via AES 128 encryption.
