Chapter 3 • Physical Components
The following table summarizes the firmware resident on the various meter
models.
Firmware Components
All firmware source code is securely stored in a standard repository and subject to
common practices of configuration management, version control, and release
management.
All firmware is identified by version number. Firmware version numbers are
defined in DLMS as an octet-string[7], or seven bytes. Release versions use three
bytes as represented below:
[Major Version] . [Minor Revision] . [Build Number].
• Major Version indicates a significant update from the previous release.
• Minor Revision indicates a new sub-system or other minor release for
integration.
• Build Number increments with each release to Aclara Product Validation on
a given series.
The SGM1400-B meter is made up of the firmware components outlined below.
Metrology
One area in the repository contains this firmware, isolated from the application
code, and does not change after certification.
Bootloader
The Bootloader firmware is integral to the application, but, like metrology, it does
not change once it is released.
