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.
Microchip says its software stack has been tested and verified by the DLMS User Association, and is customised to operate on all of Microchip's 16-bit PIC microcontrollers and dsPIC Digital Signal Controllers (DSCs).
Additionally, it says the stack has been developed to ensure seamless integration with its communication protocol stacks, including TCP/IP, ZigBee and PLC, covering a broad spectrum of smart energy applications.
As this DLMS stack has been optimised to fit in a small memory footprint, is supports using the smallest, most cost-effective MCUs possible. For European applications, the stack provides support for the required IEC 62056-21 Mode E implementation.
"The addition of this DLMS library to Microchip's smart energy offerings reinforces our continued focus on providing cost-effective and comprehensive solutions to our customers," said Mitch Obolsky, vice president of Microchip's Advanced Microcontroller Architecture Division. "Now, customers can leverage Microchip's vast portfolio of communication protocol solutions, such as TCP/IP, ZigBee and PLC, to create a fully integrated smart energy system."
